I've encountered this famous Canon ERROR 99 tonight with my 10D.

I've been having the same error before with my 300D and the reset-remove-battery work around do the trick but this time it keeps on repeating the same error.

Apparently, I found out this has been widely discussed (http://www.google.com/search?client=safari&rls=en&q=canon+10D+error+99&ie=UTF-8&oe=UTF-8) in the web - i.e. non-Canon lens usage (reported as one of probable culprit), dirty contact, etc. I got my Tamron today tried shooting in a party tonight on P mode.

I have yet to find out the suggested work around but so far the eraser-contacts method (http://www.richardsnotes.org/archives/2005/04/29/50mm-lens-contact-points/) seemed to be fine. Apparently, I can't set my shooting mode to Manual.

Anyone encoutered the same error and how did you resolve it?

Thanks in advance.

Now I'm worried. I use a 10d and I'm trying to con my dad into buying sigma or tamron

i had the same problem before with my 10D. the quick and easy solution to problem was the clean the lens contacts and change batteries. after that, it functioned properly already.

As per Canon advice, turn off your cam, remove batt(s) then replace after a few secs.

I am still at a loss why this error transpired only with my Tamron lens. I've been using Sigma for a while but this error never occured. The Eraser Technique resolved the problem naman so might as well keep a mongol pencil in my camera bag from now on.

I encountered this problem during one of my trips. I didn't really know what it meant at first but it usually just happens with my kit lens (EF-S 18-55mm f/4.5-5.6). Switching the unit off or re-inserting the battery used to work but the problem worsened. I tried switching lenses, and the problem never occured with my other lenses (my EF 90-300 f/4.5-5.6 and EF 50mm f/1.8 ii works fine). So I deduced that my kit lens was the culprit. It usually happened when i use smaller aperture openings. The lens usually just locks up and won;t go back to full open. Now my kit lens is permanently locked in f/22. I haven't found the time to have it checked at a Canon service center yet and I dunno if they could ever have it fixed.

And the error 99 can happen also to a Canon lens. Experienced this just once before when I mounted my 20D with the kit lens on a loose ballhead, the weight of the camera dragged the rest of the mount downwards. Everything went fine when I turned the camera off, removed the battery for a few minutes, then inserted the battery again.

This may be unrelated to the error, but there were times when I experience AF failure when I change lenses (kit and the 50mm). And the solution is to always turn off the camera when changing lenses. The 20D is always on, guess am just lazy at times. :)

can anyone enlighten me what error 99 is?

and can anyone also share whatever other errors they have encountered with canon units? i think this would be a great thread to help each other out with troubleshooting our cameras whenever we encounter these problems. thanks have a great day

There is actually a whole section on troubleshooting your specific camera in the last pages of the camera manual.

I wonder if you even looked at the manual at all. I know many others don't. But they do not call it a manual for nothing.

i encountered that error with my 300D and had my shutter replaced

I am getting frequent error99 with my 350d. Also, sometimes the Aperture value is [00] and I can't do anything until I switch off the camera. I guess I need to send to CSC now... :(

ERROR 99? huhuhuhu... i managed to fixed that error once at my 30D body, i just clean the connection between the body and the lens, but now it wont work, i guess i have to send it to service center now.. huhuhuhuhu... I'll see you at service center bro. GOD BLESS US ALL

Any suggestions? How much you guys think will it cost me to send it to service center? Thank you

I think it would also be best if you try to mention the camera and lens and accessory you are using when the error came out.

Simply saying, "Hey I have Err99, what do I do?!" won't help much. Maybe you can say, "When I attach my Sigma 12-24 on my 20D, it gives an Err99 if autofocus is ON but it works when I am using Manual Focus. What could be wrong?"

Then we can say, "Hmm, a friend had that, he brought his Sigma to JT and they had to replace the FPC cable and the stepping motor of the lens. Now it is ok. It cost him around 5K to have it fixed."

There you go. Knowledgebase.

OK.. thanks bro.. but i tried a lot of lenses starting from my Canon 24-70 and 70-200 both are L lens and f2.8, this is the same lens I only used with it for the past few months, then i did try sigma aswell... then i did try my friends kit lens for his canon 30D, but unfortunately it gives me the same ERROR 99... Huhuhuhuhu.

ive read somewhere that for canon its an all around error code mechanical and electronic. i also experienced error 99 i just brought my unit (350d) at the service center and thay fixed it...

for the sake of all those canon users who would eventually encounter an error99 problem.

like what mon castillo previously said. yes it is a shutter problem. but on my case error 99 was a lens problem.

had it confirmed this morning with canon service center.

I hope that this thread could help us out in identifying all these errors that we may possibly encounter in the future.... we all know that the "manual" does not have a complete listing of errors.

thanx for all those who posted.

I also encounter error 99 when my CF bug down to death yesterday...

i brought my camera to canon (last monday) due to the err 99 i encountered last weekend, i called them this morning to ask if they have diagnosed the problem! they said it had something to do with the board! i spoke to joseph and asked what happend and he said they checked the lens, the CF and the battery, everything was ok naman daw! so they changed the board, ayun it worked normally na! just wanted to know if anyone encountered the same problem? the repair will cost alot... and i dunno what caused it! im thinking that this might happen again in the future... should i sell me camera after its repaired?

mark,

if you don't mind, what is your camera model? Anyway, you can get another camera but there is no guarantee that you won't get another bad lemon.

A lot of users here encountered error99 including me with my 350d, but it does not really bother me a lot as long as I can shoot more than kaput.... :)

during the phil open about 2 weeks ago, i was shooting some of the action using my 350d, along with a 70-200 L f/4 lens that i borrowed from an officemate. i actually started that evening using my sigma 24-70 2.8, but then i felt that it wasn't long enough to capture the action so i opted to use the tele instead for the rest of the evening.

after taking around 500+ shots that night, just as i was about to shoot the womens doubles match of kennie asuncion and her indonesian partner, i was surprised when an image didn't appear on my lcd screen after pressing the shutter button. i checked out the display and there it was - Error 99.

at that time, i didn't know what it meant, so i decided to just turn off my camera and turn it on again. i did that and the display cleared up, but on my next shot, the image wasn;t saved in the card, and the same error message appeared.

until now (mainly because i was out of the country the past week), i have yet to have my camera checked. i tried using the camera with its kit lens this past weekend, but got the same disappointing result.

hope someone can help me out (am trying to join the ateneo sports shooters...).:Angry:

I encounter err99 on a Sigma 100mm macro with Canon 5D and 30D.

i encountered err99 on my 30D when i first started shooting with my new Tokina 12-24, i took the lens off and peeped through it -- stuck aperture blades! i fired a few 5fps bursts and the aperture never got stuck again, no more err99 since. :D

Hi all,
I first read this thread last Friday. I was saying to myself I hope this won't happen to me. Lo and behold, the next day (Saturday) I encountered the dreaded error 99 while shooting my niece's & nephew's bday party!

I was using a 350D, with the kit lens and an external flash (not Canon). I had taken about 30 shots using different Av settings when suddenly it happened. Turned off the camera, turned it on, shoot - intermittent error 99. It would work for a few shots but eventually will have consecutive failures. With the external flash removed, I had the same intermittent failures. I then tried another lens, 85mm f1.8, without external flash, and I did not experience any error 99 since.

I hope the problem is on the kit lens and not on the body. I'll validate this by trying the kit lens on a friend's camera (just fire a few shots).

hi everyone. i usually experienced error 99 once in every blue moon. but my problem started last week...i get successive error 99's. I tried different settings, and I still get the error. Early this week, I observed whenver the error occured, and I saw that the aperture blades are stuck wide open or stuck while closed. This only occurs with my kit lens, and when I use my Sigma 70-300 APO DG Macro, I don't get any errors.

Is it safe to say that I should dump my kit lens and now save for a good kit replacement?

Hello Rafael! We have the same scenario. My kit lens died (error99) after ~20,000 clicks with it. I think I've already outgrown the kit lens and it gave me a signal to upgrade, so that's what I did. rgds.

================================================== ========

Its either you have your kit lens repaired or just buy another lens. This is the reason why I shied away from Canon prosumer DSLRs. Some say its the lens kit, but when i mount a Sigma lens, the same problem occurred. Now, Canon is saying its the body. Kapag yung body na repair, its the lens naman. Or usually when the shutter count umabot na sa 15,000+, its the shutter's time to be replaced. Error 99 is a miscellaneous warning/defect.

Good day to all!!!

Im using a canon 350d and just last week ive experience problem with my camera. Using 35 mm and below an Err 99 always appear and i didnt get the wide angle shots that i need. The problem also occur when there is a bright background. What seems to be the problem? any probable problems?http://digitalphotographer.com.ph/forum/images/smilies/Drogar-Cry%28DBG%29.gif

im using only kit lens and tried every setting possible

Sir, also experiencing that error on cam. Before I took the shot, a strong light force pass inside the lens. After I press the shutter button the err 99 occur. But after that my cam is ok again..:)

I sometimes get err99 when using old third party lenses for my 20D. These lenses work with the 300D with no problems (possibly because 20D was newer and "locked out" older third party lenses?).

Lately, kit lens has been giving err99. Tried cleaning the contacts, and it went okay. At times, tightening/adjusting the lens on its mount works.

But err99 is pretty rare for me actually.

I was shooting with the built-in flash last night and after a while I got Error 99. It says turn on and off. I tried it but everytime I use the built-in flash I get same error. I also recharged the battery and it's full. Still the same error.

Any of you guys experienced same problem.

Thank You

@jeff,

Did you detach your lens before you had this error? If you did, see if you attached the lens properly. A friend of an officemate had this error which came from his lens not properly locked into the body. I hope you solve your problem soon. :)

worst for me, just isolated the problem which is my lens, how did i found this? tried and tested other lenses on my camera and it works, but my lens when used with other body it encountered the same problem. so now i know the problem luckily not my body kit was the problem....

So how do you usually resolve it?? Have the lens serviced??

hi guys,

i think there are a couple of other threads posted in the past that mentioned error 99. try the search function using the keyword "err99". might be able to get some additional help from older posts...

lemme know how it turns out.:Grin:

err 99 usually occurs when your camera software cannot figure out what the problem is. This happened a lot with the 20D i was using but never experienced it on the 400D yet. To help you isolate error issues on your camera, start by isolating your camera's components:

1. battery (are you using a faulty generic type?)
2. lens (check mounting, contacts, and compatibility to your camera body)
3. cf (is it defective?)
4. firmware (are you using the latest firmware issued by canon?)
5. external flash (check hotshoe contact points - may need cleaning, EF malfunction?)
6. trigger (if you're using one) - check compatibility

If you still can't figure out the problem, have it serviced by canon (while you're still on warranty)!

Anybody encountered Error 99 in Canon 400D? Please share how the error was resolved. Thanks.

I think that corresponds to the end of your cam's shutterlife... I'm not sure, though.

This is the exact message:

Err99

Shooting is not possible.
Turn the power switch to
<OFF> and <ON> again or
re-install the battery.

-xxx-
The error still persists even after turning the camera off and on and even after reinstalling the battery :Angry: Think I should bring this to Canon.

also try installing different lenses, if the problem disappears then the err99 was caused by the lens

Thanks Brando, many thanks :) i was using my kit lens when the error occured, does it mean there's something wrong with it?

Its a lens error that is sometimes solve by cleaning the lens and body electronic contacts :)

could be the kit len's aperture got stuck, happened to me once. check your kit lens.

thanks jon & manny :)

i'll check the kit lens later this evening...

Alexis,

If Jon and Manny's suggestions don't work, you might wanna try searching for other Error 99 threads (there have been a few of these already). Use "Err99" in your search. The other threads might have other potential causes of the error as well.

HTH :Grin:

sir try cleaning the contacts with a rubber eraser :)

I just started trying the new EX II flash, then with high speed shots, but I noticed it occurred when I attached the EX II ... after which I got successive error 99, even with different new lenses. I guess this is not lens related but body ....

Try cleaning the lens contacts on your body, as well as the contacts on your lens. Dirty contacts is a common cause of Error 99 warnings. Another is dirty contacts between body and flash.

i also expirience this error ...
deffective lens or improper mount of lens...

i experienced error 99 -- just by observing what's happening, I noticed that the aperture blades of the kit lens gets stuck.

got this yesterday. I was using the tamron 18~200 and didnt have problems. However I was in a low light condition and swapped to my 50mm f1.8 prime. after a couple of shots error 99 started to flash. now I cant shoot with either lens. One big problem is that I got my 40D body in Malaysia.

Help

this happened to my 24-105 after having cleaned by canon. when i was in hong kong, i thought the battery was faulty but when i replaced the battery, it still has the same error. the problem is when i try to switch off my body with the lens attached zoomed to > 24mm, the light won't go out. when i put back the zoom to the 24mm, it shuts down. i tested the lens with another 400d body and it failed as well. good thing service warranty of canon lasts for 3 months so i think they might have touched on something on the lens that shouldn't be touched in the first place.
