wow. what a hodgepodge name it's got!

here's a review i wrote a few months ago for fredmiranda.com and i thought of sharing it with everyone, with a few more recent edits.

cheers!

About 6 months ago, I was agonizing whether to purchase a wide angle lens or a nice macro lens. This was a few days before visiting the beach paradise island of BORACAY.

I'm glad I purchased this lens instead of a macro.

The angles:

The available angles to a 10-20mm lens is not something that I'm used to and if found it very tricky to compose shots properly. A small angular mistake leads to exaggerated results, because of the inherent distortional effects of wide angles. (of course everyone knows this, but me back in february! hehehe)

However, knowing the predictable distortion of this lens, you can have fun with kids! Compose images with them at the corners and see them laugh at their anamorphic images, with either huge foreheads or extra long chins, funny wide arms and what have you.

The build:

I already have a sigma 28mm f/1.8 and loved it, so finding out that this 10-20mm lens is built practically the same way is a major plus! It's short and stocky, with a nice rubbery finish. Plastic components all around, but i can't complain because it makes everything weigh in just fine. It's not heavy at all, which works fine for me.

They also threw in a petal hood, which works great when sunny. But do take care not to interchange the 28mm's hood with the 10-20mm's hood. you'll end up with ugly black borders because at 10mm you can see the edges of the 28mm's hood. several shots of mine had black borders then. grrr...

Use of Filters:

don't bother with non-multicoated filters as this lens is prone to flares and ghosting. I just put the filters on as protection and remove them when I shoot. Stack two filters and you'll find yourself vignetting.

Image quality:

It can be sharp, but it's nowhere near canon's and nikon's UWA offerings. To get the same sharpness, you'll have to stop it down at least a stop, but that never bothered me. This lens is great while on vacation (when it's sunny and all) and if you want dramatic shots, mate this with a tripod and you'll have excellent night shots that can't be beaten by any kit lens.

f8-11 seems to be the sweetspot here, but I digress. I'm not a real measurebator so i'm happy with the overall impact of my images rather than how it controls CA, colorshifts and what-not.

So without further ado, a few sample shots from the 10-20mm using either a nikon D50 or a D70s.

thanks for reading!

those are pretty good shots chewy.. they dont seem like they came straight from the cam though.

do you find the output of the lens grainy/ noisy?

Price would be good to add aswell :) thanks for the Review :Grin:

i'm sorry, but i don't understand your question about the output of the lens being grainy or noisy. Isn't that an abberation of the sensor and not the lens?

i run my shots thru photoshop for levels and +5 saturation.

but like I said in my review, i'm not a measurebator and I just wanted to share with everyone how happy I am with this fun lens :)

oh yeah, it costs Php28,500 according to the latest pricelist from JT Photoworld :)

Great photos there. I too have the sigma 10-20 and love it.

Thanks Chewy :)

@chewy...i have the same lens and i'm really happy with it...will bring it with me this month to angkor wat

can't wait for your pictures, hochi! :)

just hope it will do you justice...:-)

impressive shots from the 10-20mm sigma chewy..:)

nice shots chewy! need myself a wide lens too....but am torn between the extra wide of the sigma with the versatility of the tokina 12-24. Might drop by JT to test the lens out. Thanks for reviewing and sharing your pics of the lens. :)

Just got my 10-20mm sigma and I'm already impressed by its sharpness from center to edge. And that's shooting at 10mm wide open! As most reviewers have noted, chromatic aberation is very well controlled throughout the zoom range. Now, I need to get used to composing with a wiiiiide lense. It is quite tricky sometimes.:Scared:

i am planning to get one soon. based on what ive read, it seems like this is a great buy. so, should i take the plunge?

Appreciate the info on this Chewy... Also considering this lens vs. the Nikkor fisheye... :)

nice pics chewy. been debating this lens as well as an alternative to the nikon 12-24. so far i dont need anything wider than 17 but should i do this would be the one

Same with me Carlo, I'm trying to decide whether to get this one or the Nikkor 12-24, which cost twice as much. I read an article about lenses and focal lengths, and they suggested this as one of the lenses for wide angle shots. The shop where I get my lenses hear in KSA also recommends and even invited me over to give it a test but I think that won't be necessary anymore after seeing Chewy's gallery. Thanks Chewy :).

you're very much welcome :)

glad to be of service to everyone.

sir chewy! i got myself one na. thanks for all the inputs. magshoshoot na ako mamaya!

ei thanks for sharing the pics chewy, i'm also considering this lens along with it's canon version, might test them both in hidalgo this week, TFS

btw guys do you know how much is this lens now? thanks

Just checked out their stall at Photoworld in Glorrietta, still PhP28,500. Free filter if you will be paying in cash. I think you can pay installment 0% up to 6 mos. Asked them and the conditions still apply even after Photoworld.

thanks jester,, haven't gone to photoworld yet, lost my drive's license, might go there later,, thanks for the info

jester/darryl: yep, asked joy & orly about special rate for the photoworld event but the P28,500 price still stands (only tamrac stuff were discounted) :-D drop by jtphotoworld along pasong tamo; if i recall it right, puwedeng i-installment via credit card. don't know lang if the 0% scheme applies though. better yet, email jerome at jt1@jtphotoworld.com

Daryll bili na.....!

@ ogie - thanks for the info:)

@ doc bunz - when i can't resist a wide angle lens anymore,, i'll text you hehehe :Grin:

darryl: you're welcome. i'm a proud owner of one (a happy user at that) having succumbed to the temptation last november hahaha. i have no regrets :-D

just one question? why did you choose this lens instead of canon 10-22? thanks,,

oops, i probably got off on a wrong lane bro - nasa kabilang camp ako, hahaha. my alternative would be the nikon 12-24 (which is way beyond my means :-)) or the sigma equivalent (which is around 10k more expensive but suitable for both digital and film). i read good reviews on the canon 10-22 though. if i'm a canon user, i certainly would think it's worthwhile looking into. that is, if money is not an issue :-)

hahaha:) didn't see that coming,, but thanks anyways sa info about the sigma wide angle lens bro,,


Darryl,

BUY BUY BUY!!!! so you can lend it to me from time to time:Grin: haha

or you could buy one and help me decide between the two:)

darryl, buy it. you can never go wrong with it. it's my walkaround lens now. :)

darryl, you're welcome. i get along well with canonians (i shoot with a canon @ the office anyway). but as jeff and the other guys said, it's pretty hard to go wrong with it. it almost never leaves my camera (pity my kit lens, hahaha)

Harold great shoots can I ask a favor?

Can you shoot the same scene at 10mm and approx. 14mm? Contemplating if I need the extra 4mm. Thanks if ever.

big diff ryan :) kahit the diff of 12 and 10 is considerable

I just bought recently my Sigma UWA for 18,000php and all i can say that the result was absolutely fantastic! i even asked myself 'bakit ngayon lang?'
First respectable piece in my lens line-up! BUY IT! :D:D:D

Hi ryan...i really wanted too but the place is quite far from dubai.....but ill take note of it....hehehe...as diego replied on your post.....you can see the diff.:Grin:

Harold - what I meant was, any scene w/ a 10mm and approx 14mm shot. Hehehe... Sorry about the confusion. Didn't say it clearly.

Jowell,

You bought it in Dubai?

Thanks for the info -- good benchmark for buying the same glass outsid ethe Phils.

Dan

got this lens and happy with it :)

Diego - Congrats! I thought you were aiming for the 18-50 2.8

Diego - Congrats! I thought you were aiming for the 18-50 2.8

thanks ryan! yeah i was looking at it too. however i have my 50/1.4 which i use most of the time. it's just most useful to have all that speed eh.

and when i tried the 18-50 out i was disappointed it doesn't have a full time manual override (small detail lang but i was excited for it kasi HSM).

Congrats Diego on your new lens! I'm also interested in this lens but not at this time to get it. Maybe a sturdy tripod first.:)

I'm also confused w/ this one, but I have a 14mm so in no hurry yet. Want a 18-50 hsm first hehehe

Diego - Maybe if you have time, pls. shoot a scene w/ 10mm then almost/around 14mm. I just wanna know what I am loosing (the 4mm difference). Thanks. Try that lens at Narra park or St. James in Ayala.

thanks emmanuel, yup i think a nice tripod would be next on my list :)

aah if you have a 14mm then get the 18-50mm first. tell you honestly, it's a really nice lens. i'd probably get one if i had the money but i got the 10-20 first because i have a 50mm anyway. both are very well made, not exactly the sharpest (compared to the nikkors) but good enough

i'll do that 10 vs 14mm comparison when i've time :)

what 14mm lens do you have by the way?

Diego - Planning to get the 18-50 2.8 HSM so that it will AF on my D40x but if ever I dispose of the D40x then maybe the Tamron 17-50 2.8 w/c is also sharp.

I have the Sigma 14mm 2.8 HSM.

Thanks in advance.

took this inside a resto bar here in dubai...using my sigma 10-20mm...

Just got this lens earlier. from JT... the 2 copies i have tested are both sharp seems that they have a couple of good stocks there.

I also met Diego Jose earlier in JT. Nice to meet you bro!

Hey bud! hahaha it was such a coincidence seeing you there! Congrats!

Chewy is right regarding the composition part and angles..... medyo hirap pa ko to create a good composition when using this lens...

Hey Marvin nice image. Where is this church? I like the simple design and the architectural daylighting employed. Very nice. :Grin:

Hi Randall,

Actually its a newly constructed chapel in Silang, Cavite within the Chosen Children Village. I have the same comments as yours, its really an amazing design, there were no lights yet installed inside ...all were ambient lighting. Aside from this did you notice the blue and red color cast in the wall? according to the architect it signifies God, Heaven (the color blue) and the blood of christ for the red. Pretty cool eh? it was designed by a US based architectural firm.. stan allen architects particulary Arch. Carlos Arnaiz..

nice photo marvin :) looks like you're doing great with your lens!

Thanks bro...hahah yeah....I am enjoying this a lot! I hope I can master the angles more... im having a little trouble with the distortions... still finding and experimenting on ways to make these distortions work to my advantage hehhe...

Thanks Marvin! Yeah, the cove lighting got my attention. I really love these modern minimalist designs.

Stan Allen? I think I've read of them before during the new WTC design competitions in Architectural Record. Though I'm not sure if they're one and the same firm.

I have to pay this church a visit sometime. :Grin:

you should really try to visit it..... especially at night... they tried to put in some temporary lights inside to check the effects of the light from the outside.. and grabe.. what a view! They projected it to be finished before xmas.

Thanks bro...hahah yeah....I am enjoying this a lot! I hope I can master the angles more... im having a little trouble with the distortions... still finding and experimenting on ways to make these distortions work to my advantage hehhe...

distortion-wise it's only at the very edges of the frame of the widest end :) the other focal lengths sobrang minimal lang. so if you want it distortion-free at the widest end, crop mo lang ng konti ;)

Thanks for the tip bro... cguro i need to avoid placing important objects at the edges para di distorted ang itsura nila... pero how about for structures such as buildings.. like for this project kasi (the chapel) the client wants me to avoid as much as possible yung skewing ng structure..

like for this photo this is actually the shape of the chapel.. i mean square

http://farm3.static.flickr.com/2064/2071288174_0bc1d10f0e.jpg

Pero I guess we cant avoid skewing unless you go to a higher ground right? Like for this one...naging trapezoidal na yung shape nya http://farm3.static.flickr.com/2126/2071288394_4c38f19808.jpg

aah that's the effect talaga kahit anong lens. if you want to avoid that effect na parang vanishing point (since you're from the ground pointing up) either shoot further away to avoid pointing it up so much or invest in the nikkor PC lenses :)

those PC lenses are made for architecture talaga kasi it fixes that effect, kaya pangalan perspective control or something :)

Darryl,

BUY BUY BUY!!!! so you can lend it to me from time to time:Grin: haha

this is the guy responsible for me to get the sigma 10-20mm..

3 words regarding the lens... i'm lovin it. :)

Those are converging verticals. Either you shoot directly at the midpoint of the vertical lines of the structure, or use perspective correction software like Photoshop's lens correction tool sacrificing a bit of image quality from the interpolation...

http://i3.tinypic.com/6utu33b.jpg

Or buy a Tilt-Shift lens. The problem with tilt-shift lenses... they are very expensive, built for full-frame (no ultrawide focal lengths), and manual focus. :)

i'm okay with manual focus since i'd be using small apertures for architecture. Tilt-Shift lenses? yan yung canon name right? they're called PC lenses on nikkors diba?

Shift, Tilt-Shift, and Perpective Correction are the general terms. Pentax uses the term Shift; Zeiss and Schneider-Kreuznach use PC as well. In the end, they all serve one purpose, as perspective correction lenses. :Grin:

here are some from my 10-20 sigma.. got it a few weeks...

good thing that this topic was discussed. I have a wrong assumption about shift lenses. I thought they were like Teleconverters where you can put your UWA lens at the other side and it will just shift raise your angle to avoid these skewing of images.

When buying this lens, what and how do i check it if its a good unit?

Thanks

i did a sharpness test along with my 18-50/2.8 EX DC HSM and nikkor 50/1.4 at different focal lengths and apertures

wide open was okay. stopped down it performed very well. center was very sharp while the corners were a bit softer

how much is this lens nowadays?

24800 bnew at JT :) that's with a full year warranty and great service from them, they're the official distro and support here

Went to JT earlier and found out that this gem of a lens is out of stock till the end of the month. I'm not sure if I can wait, but I am contemplating heading to Quiapo and get it there. Does anyone know the price there?

Also, how does one fix the weird edge distortion @ 10mm with photoshop?

I've been looking around for a good UWA lens for the past month and somehow this lens managed to float under my radar. :Oops: Now that someone has mentioned it to me, I'm seriously considering it. And at that price, it's also considerably cheaper that the other lenses I'm looking at.

And from the research I've done, most owners are pretty satisfied with the lens and there has been a good amount of praise for it. The only common big negative I've heard is that distortion along the edges.

Might jump on a lens purchase in 2-3 months and this lens is making a good case for itself. Sana bumaba ang price come summertime. Hehe.

This might help your decision:

http://www.bythom.com/sigma10to20.htm

@ dexter, 22.5K in Mayers last time i checked which was last january...

@diegojose - thanks! that was quite informative.

@Paul - whoa, a couple of thousand cheaper in Mayers... might opt to buy it there...

hmmm, this (http://www.photozone.de/active/survey/querylenstxt.jsp?filter=%22brand=%27Pentax%27%20OR %20brand=%27Sigma%20AF%27%20OR%20brand=%27Tamron%2 0AF%27%20or%20brand=%27Tokina%20AF%27%20or%20brand =%27Vivitar%20AF%27%22) doesn't cast a good light on the Sigma AF 10-20mm f/4-5.6 EX DC (HSM)...

although that is just a survey and the actual photozone review basically says that the lens is relatively good.

Try out the lens yourself :)

Dude, you rock. Rock on man... rock on! I wanted to use a photographer's compliment but not that creative.

I must get my hands on this lens. Must beg, cheat or steal one.

In the meantime, can anyone post pictures of interiors of rooms and houses shot at 10mm?

Here's one interior shot at 10mm. The side corridor of San Sebastian Church in Lipa, Batangas...

@Franz and Jowel

Thanks for sharing guys.

Franz, I spotted the distortion on the edges. Any tips on how to correct this is Photoshop?

Jowel, yours on the other hand I can't seem to notice any, did you shoot at 10 mm? If so, how did you fix it?

the ceiling was rounded so there's no way of telling about the distortion but if you'll closely enough on the lower right portion of the image, you'd notice the diagonal pattern on the floor isnt not too diagonal.... anyways, i'll try to post some more images shot in 10mm with an obvious distortion... i think with this focal lenght, distortion is inevitable....but this lens is really handy! i didnt regret buying it... :)

Newbie here. I am planning to get this lens from amazon for $469. I am not sure how to test this if it has any defects. Can anyone give tips on how to test this lens when i get it out of the box? Like point it on a specific type of subject then zoom in the computer to check the actual output. Hope you guys can give me tips on how to test this lens, I wanted to order this the soonest to I can make great shots here while in the US. BTW, I am using a D40 with Kitlens and SB400, any accessory suggestion accepted to complement this lens.

@Jay

Best way to test it is to take a couple of shots, wide open and at F8 or F11 and check for sharpness on your monitor. I read that this sigma lens has sharpness problems, some copies are tack sharp some are soft. Check the corners and the center image.

@others...

I'm set at getting a UWA, but I got second thoughts on getting the Sigma. Thankfully, I have the budget for the more expensive Nikkor. Just wondering if the more than double price is really worth it vs the extra 10mm of the Sigma . I plan to take a bunch of pictures of Interiors of houses... any thoughts?

Hi Sir,

No CPL sir... only UV filter... no PP.... the Camera was set to Vivid+ thats why it boosted out the color

Hope you guys can give me tips on how to test this lens, I wanted to order this the soonest to I can make great shots here while in the US. BTW, I am using a D40 with Kitlens and SB400, any accessory suggestion accepted to complement this lens.

try to test for front/back focus - you'd have to consider resending these if they happen to be slightly faulty, though.:Grin:

@jay

I read at the Flicker Sigma 10 group that one way to check for the bad copy is checking the sharpness of the left or right side of the image. (the Sigma 10-20 is almost always sharp at the center.)

One way to do this is to look at your LCD screen with the image you took, zoom in just before the image gets pixlelized and move around the image and try to look for softness. if you don't see any, then you got a good copy.

@cedrick

I never read any focus problems with the 10-20. That is more manifested with the 30mm 1.4 though!

editing this so that only the links would show instead of the actual photos (para mas mabilis magload yung page) :)
I don't wanna trust my eyes so I'm asking for the opinion of the people here... (and I may have also been pampered by my really sharp Pentax 40/2.8 prime lens so most other lenses might seem soft) ...but I really think I got a soft copy. Here are some test shots:

Shots were taken at around f8-f11, 10mm, 1-3s, indoors at night with the flourescent lighting and my camera on a tripod:

Hmmmm, center looks fine, but the right side of the image looks soft... I read this as one of the things to look out for in the 10-20. Softness on one side... I can be wrong though. I'll compare your shots with ones taken with my copy of the lens.

But IMO, you've been spoiled by your 40!:D My zooms always look soft when compared to my primes...:)

just got one. from my trip to china. very happy with it...

Thanks for your input Franz! Oo, love ko talaga 40/2.8 ko. It will still be my primary lens. Hehe. I'll try and post some outdoor photos tomorrow of the 10-20.

In any case, I love the perspective made available by this lens, so I'm happy with it.

As a sidenote, I bought this from Mayer's and in light of all the stories about Mang Ramon that I've read and heard, he actually seems like an okay guy. Malakas lang dating niya, but he was quite amiable and helpful. Although he did go into this short tirade against Pentax, but it was more because of a struggling market for Pentax here in the Philippines and not aimed at the quality of the brand. So it was reasonable enough for me :) Hehehe.

@Joel: How much did you get it for? In peso equivalent?

sharing again...

@marvindungao: omg, that's an amazing photo. That's the kind of shot I had in mind when I set my sights on this lens. What PP did you do on that? Hopefully, on my next out-of-town trip I'll be able to share similar shots.

Anyway, continuing my experimentation on whether I got a good copy of the lens or not... here's an outdoor shot:

Hmmm... it looks more or less fine to me... but maybe keener eyes could share their opinion?

@paolo

The outdoor shot looks sharp to me. I did see the softness on the right side in your indoors shots though.

Maybe the fan was rocking your tripod?

@dexter: Yeah, same observation here actually as with you and franz. the indoor shots looked a bit soft (I doubt it was the fan, but I'll try again) which is why I initially thought that the copy I got wasn't good. But on the other hand, the outdoor shots that I've taken look quite decent.

In any case, I just it just goes to show that whether or not I got a good or bad copy, its effects are not that visible so it's all good. ^_^

More about the lens:

On a pentax forum (not here in dpp), they have this weekly mini-challenge and this week's theme is "Vanishing Point". I got excited since my lens arrived just in time for that challenge. It's so easy to take a VP photo using a UWA lens! You just have to pick your spots and take a really good one.

imho, my submission is decent, but not exactly winner's circle material. this was it, taken at the backmost row of a passenger bus (although this has been cropped already at the left and right sides so you might not notice much distortion):

Hi Guys,

I have a 10-20 Sigma. My friend has a tokina 12-24 which i think is more sharp and faster.
I love this lens. here is my share

http://farm3.static.flickr.com/2169/2278921245_673f28c94d_o.jpg

here is another one, distortion is very nice. i have printed this image on an A2 paper, you can see its not that sharp.

http://farm2.static.flickr.com/1316/869365780_0dc767c4b7_o.jpg

@ogie

I love your photos, but your comments above confuse me: You say you like the sigma 10-20 but say that it is slower and not as sharp as the tokina. And your second comment says that you love the distortion but the sigma is not sharp at all. So, my question is, is the sigma 10-20 good for you? or is it too soft and we are better off getting a tokina?

2 things dexter:

1) I love UWA lenses but the sigma is not that sharp, the tokina is more sharper but has 2mm difference (12-24mm). If you do not mind the 2mm then go for it coz some people really needs the 2mm specially on thight locations. Ika nga bitin pag 12mm.

2) The sigma is good enough and cheap, since its a third party lens, its fun aslo. Use a Star six filter. See below. U can feel the distortion, makes u feel that your using UWA lens. hehehe. Otherwise if you have some more dough, go for the Nikkor lens, it expensive but u cant go wrong. Ika ka nila "Save your money to buy better glass":Grin:

Hi Sir... in Cam Processing.... D80 Image options set to vivid+ and voila!

@ogie

I'm torn now. hehehe thanks a bunch! I was looking to get the sigma but your comments made me think twice. luckily i have enough cash for the Nikkor. But not sure the double price makes it worth it.

I plan to shoot house interiors with it aside from the landscape photos. Chances are, I'm going to need that extra 2mm. I just hope I get a good copy.

Hi Dex...just my personal opinion... choose one.

I firmly believe that both have their own drawbacks and advantages... and the major factor of your photo will be you...not just the lens just my 2 cents. I know you will do great with either of the lens...

@marvin

Thanks for the words of decisiveness. Hoping JT will have it soon.

dexter - someone is selling a used sigma 10-20 at the other forum.

I use to have a Sigma 14mm (that I really loved) but the 4mm difference on a 10-20mm made me want to get a 10mm or wider. Saving up for a 10.5 fishy since I want something different (and you can de-fish it)

@ryan

Thanks for the lead man... but his asking price is too high, also it's a year old, so good bye warranty. Will find out if he is willing to lower the price,

I wish DPP has a selling area.

Same reason why I got the brand new instead of the second hand....its the warranty... i realized that since Im going to use this lens for business and will be used greatly... i need to make sure that the lens is in great shape warranty is still valid.

Finally got my grubby little hands on a Sigma 10-20

Did a couple of test shots and I hope the more experienced peeps here can help tell me if i got a good copy. From what I can see, its sharp equally at the top and bottom of the image. EXIFs include: 10mm, F/8, 1/60, ISO 200, bounced the flash off the ceiling at TTL mode.

http://img.photobucket.com/albums/v731/deckchua/20080227-_DSC5753.jpg

Just some observations:
Soft Wide open at F4. Best used at F8 or F11. Built like a rock. And so far, fun to use! Need to learn how to use it first!

dexter - congrats! So they have them now. Joy looks thinner than usual on an UWA lens.

Is that a D200? How much are they new there?

@ryan

Yes it was a D200, but i failed to ask how much. I wanted to minimize my knowledge to reduce any temptations! It was a CDSC unit if I remember correctly.

Anyway, does my copy look sharp to you? hehehe i'm a measurebating beeyotch.

Just got the lens today, weird thing is the lens cap is already pinch type. Does that mean this is a newer set of 10-20mm manufactured? Maybe they heard us complaining about the pinch type cap. Any way, one thing i have also noticed is that it has no more switch for MF/AF on the lens. Not that it bothers me, i just wanted to know if the other copy's also has the pinch type lens cap and has no AF/MF switch.

http://farm4.static.flickr.com/3237/2321910211_d8f26eefc0.jpg

Wow it has a pinch-type lens cap!
I bought mine last December and it still had the traditional lens cap...
And yeah, mine has an AF/MF switch.

It's a Canon mount.

Dont worry my Sigma 10-20 has no AF/MF switch too! What I like is the new lens cap. Do they sell extral ens cap...wanna buy 3 for my line up:)

Canon and Sigma mounts have the AF/MF switch. Nikon mounts do not...

I dunno about the lens cap... Doesn't it look like it could scratch the lens if you're a little careless putting it on?

Tried some shots indoors, not sure if the shots i got are sharp enough. Can anyone share indoor shots and outdoor shots on 100% crop. Thanks!

Will it mess up the HSM if i accidentally turned the focus ring while it was still autofocusing?

it won't, don't worry about it :)

try doing test shots on a newspaper on the wall at different focal lengths and apertures. take the shots so that the newspaper fills the frame. then you can see where it's sharp by looking at the letters

Shot i take on a brick wall. Noticed it was sharp on the center, but a tad soft on the other areas. Do you guys have the same results?

http://farm4.static.flickr.com/3271/2324754887_988c101556_b.jpg

seeing the photo I have attached below, would you say i have a good copy?

Its common in all UWA of Sigmas...they say it is also found in some UWA lenses

Care to share addt'l details of the shot; how far were you from the wall? aperture? shutter speed? and focal length used?

From my view, the corners do look soft -- but is expected, to some tolerable degree of this lens. The lower side of the image, from left to right, is more soft than the other three corners. The camera may have been slightly tilted while shooting the wall. Nothing alarming, in my opinion...

Go shoot the outdoors; any real-world problems you may have with the lens will manifest on your images when you're out there.

Cheers! :)

Focal length was 10mm, ISO200, F8 approximately 1.5 - 2ft from the wall. Forgot the shutter speed.

try the newspaper. it's easier to tell which is sharper because the letters become more legible

Wow!!! Pinch type lens cap. Gotta get one of those.

Hey guys! I got one from JTPHoto recently (before the price went back to the pre-PWA level). Its a Nikon mount and it has no MF/AF switch indeed.... the cap however is still the non-pinch type :-) Gotta test the lens on a newspaper.. thanks for the tip.

got mine from HK last month and the lens cap is pinch type. nikon mount so no af/mf switch. did the newspaper test and i believe it is a good copy.

i changed my sigma caps to nikon pinch caps hehe

Hey bro.. how much is the pinch cap in JT?

I can't remember but they were really cheap, siguro around 300 bucks ata. but these were generic ones and i really didn't like them, they felt really cheap too (just my opinion). the spring action wasn't smooth and all.

my family went to the states a few months ago and they just got me original nikon lens caps as pasalubong hehe

The newspaper test.... thanks for the tip Diego!

I had to try it myself and here's what I shot:


http://img.photobucket.com/albums/v731/deckchua/_DSC6680.jpg


EXIF: ISO 200, 10mm, F/8, 1/60
Flash shot through Shoot-through umbrella at 1/8 power

I'm detecting a slight softness on the left side... but can be from the combination of the distortion and me not taping that part on the wall. Anyway photobucket resizing it made it a bit small for pixel peeping....

Any comments?

hi dexter. here are some tips to help with that test:

-tape the newspaper on the wall flat, dapat flat yung paper
-make sure the camera is pointed directly perpendicular to the newspaper
-fill the frame with the newspaper to the edges
-use a tripod or stable surface, no flash and lowest iso and a decently lit area para balanced yung lighting and use aperture-priority
-try different focal lengths and their different apertures. sometimes different focal lengths perform differently (i.e. wide end backfocuses but the other focal lengths focus well example lang ha)

that way the depth of field will be perfectly flat so you can really spot the soft areas.

How far should the camera be from the newspaper?

enough to fill the frame. meaning it covers what you see in the viewfinder

At the moment... I think I got a good copy.

Initial inspection of the shots at different focal lengths and different apertures yielded consistently sharp center and consistent sharpness/softness at the edges.

I haven't pixel peeped extensively, but the most important focal length at 10mm looks pretty good at 4, 5.6 and 8.

Thanks for the newspaper tip Diego. What if the results show your copy is not sharp, will JTPHOTO exchange the lens? Or put it simply, will they concur with the results of the test?

Nick - They will correct it by calibrating the lens for you.

hi nick, yeah i think so if you got it recently lang naman. joy is easy to deal with naman.

hi guys! what's a good pola filter for the sigma 10-20mm? i guess a thin one, but what brand would you recommend? how much do you think would it cost? sigma sells their wide pola for P5k. mahal naman :)

ledesma pala tayo lahat haha!

hoya or marumi :) i like sigma's multicoated UV filters though.

however there's a weird and uneven effect in polarizing in this lens because it's so wide, the colors don't become even. but if you like it, get one.

Hi Nick, talagang may corner distortion ano? Pero I think it's too much to ask na wala. Sana you also tested for front and back focusing issues.

Hi Nick, talagang may corner distortion ano? Pero I think it's too much to ask na wala. Sana you also tested for front and back focusing issues.

how do i test for front and back focusing?

There is a link buried in one of the Sigma topics, but I have them downloaded. Send me a PM with your email and I'll send them to you.

easy way to test for front focusing is to get a magazine or newspaper with a few lines that have pretty large font. use selective focus, and then focus on one in the middle at a 45 degree angle and see if the middle one is in focus. front focus will show the nearer line of text will be sharper than the middle one (you focused on) and back focus will show the further line in focus.

if you use text that is too small it may confuse the focusing system, dapat kasing laki lang as the focus point in the middle.

about your test nick, i'll check it out later i have to run now :) but try the test again in apertures f4, f5.6 (since the 20mm's min aperture is f5.6), f8 and f11 instead of f22, and at the focal lengths of 10mm 15mm and 20mm

a bit tedious but more systematic :)

The primary problem with this lens won't be front or back focusing since it's an ultrawide, the lens' depth of field is so great, it's like on hyperfocal all the time.

You'll be better off worrying about corner to corner sharpness and light fall off which I found as it's biggest weakness. Using 2 filters stacked together, it has the worst fall off performance I've seen on an ultrawide lens even at f/8 and smaller. But this is easily correctable. When stacking a low profile Kenko Pro1D and a Hoya NDX400, you will see the filter ring at 10mm. It also suffers from a bit of unusual flaring which might scare some Pentax users who are spoiled with SMC.

I also observed that it has a slightly warmer color response compared to the Canon 10-22 and Pentax lenses I've used. Not that this is bad in anyway. It's just different.

On the up side, it's a great lens. There's very little chromatic aberrations or purple fringing, if there is any. If you get a good copy, it's highly recommended. I used this lens recently on our Palawan (http://www.digitalphotographer.com.ph/forum/showthread.php?t=13132&page=2) trip ( thanks Franz! :) ) I might get one myself. :D

true about the front focusing but it's something i paid for so might as well have it work properly. i noticed too it's a teeny bit warmer in color.

great photo you got there.

Thanks diego! Hope to try it out longer next time. It was a spur of the moment decision to test it. Drove to the coastline at almost 6pm near the house and just took some test shots with a tripod. Now if only i had a polarizing filter...The last shot was with an orange cokin filter which i hand held (hehehehe) in front of the lens.

I'll try the back and front focus suggestion. Anyway since this has local warranty i can take my time to test if it is a good copy.

Sorry, the third (and not the last) shot below was with a cokin filter.

you don't need a polarizer if the sun isn't high up, but you can use it as an ND since it usually darkens the scene by a stop or 2

nice idea with that orange filter!

thanks for the advice. when i had a p&s digicam, id hold the filters in front and shoot through them :)

Of course the 12-24mm Nikon will always remain the dream UWA, but since it remains unreachable as of now, the Sigma will suffice for the time being.

After a long wait and series of "out of stock" periods, i ( and a couple of friends) finally got copies of this lens. woohoo!!!

Now, i can again justify going out of town and shooting some landscapes to learn how to use, and test out this lens.


PS.
Does the lens really have this tightening "feel" when you zoom in or out from 14 to 20 mm? Or does it smoothen as its used more & more? (trans: lumuluwag din pag araw araw ginagamit?)

Also, have to test if this is a good copy. Presently testing the other sigma, the 18-200, with varying results, and i'm not yet convinced...
:)

Probaby sigma has this tightening issues with their lenses ... i got their 18-200 OS HSM last week, and it also has its stiffness on 50mm-80mm.

has anybody tried the cokin P series holder(up to 3 filters) with their 10-20? any problem?

has anybody tried the cokin P series holder(up to 3 filters) with their 10-20? any problem?

Haven't used the P series holder but i've tried cokin with the Sigma, holding the cokin filters in front of the lens at 17-20mm. Here's a sample:

http://farm4.static.flickr.com/3193/2415728014_54655c9955.jpg

thanks nick. I was actually wondering if the holder will cause vignette on 10mm.

thanks nick. I was actually wondering if the holder will cause vignette on 10mm.

im not sure if it would below 17mm. i just hold it. its faster. hehehehe..and i can just shift to one filter to another. a bit primitive but it works.

maybe i should try that. :D isn't hard to hold a gradual colored filter?

has anybody tried the cokin P series holder(up to 3 filters) with their 10-20? any problem?

yes, @10mm you will be seeing the sides of the holder (regular 3filter holder), but once you adjusted to 12mm, everything is clear:Grin:. I would suggest, get the holder for UWA, but it can hold 1 filter only.

maybe i should try that. :D isn't hard to hold a gradual colored filter?

its hard at first, but you'll get used to it.

Dude, you rock. Rock on man... rock on! I wanted to use a photographer's compliment but not that creative.

I must get my hands on this lens. Must beg, cheat or steal one.

In the meantime, can anyone post pictures of interiors of rooms and houses shot at 10mm?

As requested

some other concerns/observations:

intro--- i'm using a d40x...

the AF tends to hunt back and forth when using AF points to the left or right of center. when using the center AF point, the focusing is lightning fast. this happens when the off-center AF points are on areas of the frame which are plain dark or light.

Read about the same incident on Ken Rockwell's page:
"Because it's not as sharp at the sides my D200 won't always focus properly with any other than the center AF sensor." - Ken Rockwell (http://www.kenrockwell.com/tech/digital-wide-zooms/comparison.htm)


anybody experienced the same? is this a cause of concern?
your input is greatly appreciated!
thanks in advance!

Hi Guys! Is these lens available in Hidalgo stores? If yes, do they accept cheques as payment? Thanks in advance! :)

i don't think checks are accepted, puro cash sa hidalgo

i have a feeling it's with the D40x, as not all cameras have the same focusing capabilities. not all the focusing points are the same too, usually a few of them lang are the "cross type" or somethingamajig which i'm assuming are better or something :D

thanks diego! will try to do some more testing, but after using it in Taal yesterday, i'm pretty happy with the capabilities and performance of the lens. :)

How about in JT?

Unless you are a frequent buyer from them and have good credit standing I dont think JT accepts checks. Only cash and credit card payments. You can call them up to check.

Hmmm... ok... Thanks emmanuel :)

How about in JT?

card mo nalang sa JT, you can also do zero percent installment :)

Sara, I'm not sure about the check but Mayer Photo has this lens. Last time I inquired, it was P20k. :)

K, thanks someone also offered with almost the same price..... still thinking if it's a need or more on the WANT side:Grin:

I have never regretted getting the Sigma. My only problem is finding the 77mm IR for it. Here's a recent photo taken in Laguna Bay...

Try Infomaxx Trinoma:)

I did Diego, the price was really way above my budget, P6,500 i think. Not bad actually as the Hoya cost about $140 at Ritz and they have to order it.

Sample shot last month using this lens. This is my play ground during childhood. I know what you are thingking. The sky is not the ground I'm talking about, it's the unnoticeable rice field. :Grin:

http://img253.imageshack.us/img253/3225/dsc0027kp7.jpg

Here\'s another sample from this great lens! (with CPL and GND filters)

http://farm4.static.flickr.com/3081/2504740455_29ac84d52e.jpg

ayun oh! naka filters pa! musta gamit ng hitech with the 10-20? handheld yung GND?

Uy Diego! Yep, handheld! It\'s ok if .3 or .8 seconds, hassle if 10 seconds the exposure! hahaha...

OT: btw, I\'m reeaaaly close to getting the 50-135 na... not the 16-50 though, I\'ll just use primes between my 20mm-50mm gap! hehe...

With the sigma 10-20mm (at 20mm) with a Hoya Polarizing filter.

The second pic's edges seems soft. Did you stop down for this shot? Maybe you may want to have your lens recalibrated :)
