Hi,
I have had my canon for years and it has been a faithful friend for all that time and the 6-7 months that I have used it nearly everyday on the road.
Last night I went to watch a Thai Boxking match, pulled the camera out of my bag and realised I had left it on since I last used it. Automatically the camera had put itself to sleep. Thank fully. Took about 400 photos of the entire evening but not without issues. Every so often I was prevented from taking a photo and the screen showed 'error 99'. Today this is all it shows and can not take any photos.
I have changed lenses, I have cleaned the lens and the body where they meet, I have recharged the battery.
Please help me, I need your advice to solve this problem..... all internet forums seem to be dominated with slagging matches against canon. I just want a solution....if there is one.
Thanks
Jess
Reply to this I have found information on this excellent article:
Canon DSLR Error 99 fix. I'll include a description of how to rectify the problem taken from this site:
To isolate the cause of the issue, we suggest that you do the following:
1. Turn off the camera.
2. Remove the lens, battery, and CF card.
3. Allow the camera to sit without power for approximately 20 minutes.
4. Insert a fully charged battery, and turn on the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99″ message appear? If it does, then the camera should be
serviced. If it does not, then please proceed to the next set of steps:
1. Turn off the camera.
2. Insert the CF card.
3. Turn on the camera.
4. Format the CF card in the camera.
5. Depress the shutter button as you would to take a picture.
Does the “ERR 99″ message appear? If so, then the CF card is the most
likely source of the issue. Try using a different card.
If the message does not appear, please complete the following steps:
1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser
or soft cloth. Be careful that you do not let any debris fall into the
camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.
If the “ERR 99″ message only appears when one particular lens is attached, then that lens should be examined by a service technician.
If you see the “ERR 99″ with a different Canon lens attached, then the camera should be serviced.

Reply to this Had a quick google - none of the news looks good though. People have sent the body off to Canon, who've returned it without a fix etc etc.
Have you tried it with a different lens at all? The contacts might not be dirty, but damaged...
Reply to this Thank you both. I shall try and let you know how it turns out. I really think I might cry - the message appears everytime a wonderful photo opportunity emerges and then of course in an instant it is gone. It is so frustrating. If the above doesnt work I may seriously consider buying a new body.
I have tried all three of my lenses and the same happened to them.
Ill give the above ago and get back to you hopefully with good news
Reply to this tried the above and thought it worked. but after a few shots the error showed up again.
it seems that I have to remove the battery,put it back in again before taking shots. Have tried to get the camera to start shooting at 0 again in case it keeps trying to write over the previous image but it wont stay. The error seems to show when i turn the camera off, then turn it on again later to take photos without taking the battery out.
one of the sd cards i tried is new so its not a faulty card.
i just dont know!
😞
Reply to this Could be a battery issue, do you have a spare battery you can use?
Reply to this no I dont. I will try and find a canon shop tomorrow and see what they can do to help/test. otherwise ill be looking up the old travel insurance policy to see what i can or can not do
Reply to this there is a canon specialist which deals in Bangkok and he serviced my camera and upgraded the firmaware - it works!!!!!!!!!!!!!
thankyou for all your help x x x
Reply to this Excellent news! A service and firmware upgrade is all it needed, glad that it wasn't any worse.
