dont know the price for this second one.

so which is better between the two? hope someone here in DPP is kind enough to enlighten me. thanks alot!

first one has the hood attached... 2nd one doesnt

theyr the same lens from what i see

although there are 2 10-20mm's being offerd by sigma

first is the one above with a variable maximum aperture of f4-5.6 (http://www.sigmaphoto.com/shop/10-20mm-f4-56-ex-dc-hsm-sigma)

while the other is at a constant f3.5 (http://www.sigmaphoto.com/shop/10-20mm-f35-ex-dc-hsm-sigma)

+ 1 on this, these are basically the same lens. Given the price quoted from pixel pro, it is definitely the 4-5.6 version (taken that the price quoted is for a brand new unit) while it is clearly shown in the marking on the 2nd photo that the lens is also the 4-5.6 version. The lens hood attached might have confused the TS to think that these are two different lenses. Btw, lens hood is already included when u buy the lens. HTH

The older F mount version of this lens does not come with the AF/M switch (1st pic). Recent models & Canon mounts have it (2nd pic).

the one that i bought have no af/m switch, and it cost me around 27k. i just noticed that there's no switch when i got home and checked the web.

my questions now are:

-does the recent models have any difference in terms of IQ?
-does the price that they gave me worth it for the old version? or the recent models price is still pricey (the 3.5 version cost around 30k so i guess it will not go that far)

i never really thought that there's an old version of this one :)
please advice so that i can still ask them to replace this one with the newer model. thanks

IQ wise they should be identical, same goes for pricing. only advantage of the newer AF/M switch is not having to dive into the menu to disable AF.

be sure to check for front/back focus issues.

thanks alot sir, i appreciate it :) kudos!

The second picture is the Canon, Sigma mount.

First one is the Nikon Mount.

Nikon mount doesn't have the AF/M lock near the mount ring.


I'm using the Nikon Mount one.
