This probably isn't it, but just to be sure... Make sure you have the latest firmware loaded. I was getting constant Err99's with my 10D and a new Lexar 40x card until I loaded the latest firmware, even though the firmware notes mentioned nothing about addressing CF card issues. Now everything is fine.

Canon 20D. Says "Err


Error 99 is a result of an electronic communication problem normally between the lens and the camera body.

Use a red pencil eraser to "polish" the contacts even if they look clean do it again.
Take care to keep dirt out of the camera and lens bodies.

Another thing is often times the camera firmware needs to be updated to move on from this.

Another thing is the CF cards? The 20D was in an era where pretty well the larges CF card was a 2gig,I use several 1gig however if you have updated your cards to say an 8gig the firmware just can't handle the card.

Okay moving on clean the lens and body, update firmware, make sure the CF card isn't beyond the camera capabilities and last if all that stuff didn't work the it's possible the actual sensor is really dirty and needs cleaning.

The worst case scenario is that the shutter has failed. The Canon 20D is only good for 60,000 actuation's.

Hope this give you a few options

Tip

Canon D-SLR error 99!


Error 99 is a generic failiure that can be related to different parts of the camera. Memmory card, Shutter, Flash, Lens even humidity and temperature could be the reason. Dust and fingerprint on the contacts of the Lens, Memory card and the battery could caus the error too, so the first thing to do is wipe the contacts clean and try the camera, if that doesen't help then follow the procedure below;

To find the cause, in a place with normal/average humidity and temperature:
1. Turn off the camera!
2. Take out the battery.
3. Take out the memory card.
4. Remove the lens ( don't forget to cap the body and the lens ends! )
5. Put the camera in No Flash mode.

Now with a fully charged battery inserted, try to release the shutter(take a shot). If it is still showing the "err 99" message then the problem lays in the Body (Sutter(*), Mirror, Image Sensor, etc)(**). But if it works then:

1. wipe the contacts on the memory card and put it back in and try again if the error 99 occurs, then you have a faulty memory card or the contacts inside the memory slot are bent/crooked, look closer to make sure. if they look ok and the camera works then,
"With the memory card inserted";

2. Wipe the contacts on the lens and the camera, put the lens in manual focus mode then attatch the lens. Put the camera in Aperture priority(Av) mode. Set the aperture to the widest( the least number) and try. if it works then turn the aperture to the highest number and try again. if the error comes up, then your lens' aperture servo could be faulty (**). If you dont get the "err 99" then turn on the AF of the lens and try, if the error happens then the focus motor is the cause(**). To be sure you can test the camera with another lens. If the camera does work normally, then,
"With the lens on!";

3. In a dark place put the camera in "Auto" mode and try to release the shutter(shoot) if the flash does not pop up and it does not respond to you trying to pop up the flash manually, then your flash release mechanism is the problom(**).

These are some of the most occurring causes, there might be others. A photo store sales man told me it will cost me over $ 200 to repair my camera. My problem was the aperture servo of the lens. I hope this procedure helps you to find the problem and maybe put the money on something more necessary!

(*)Sometimes the shutter parts fall out of order. You could lift the mirror and have a look at it, if they are not parallel and even, then you may be able to push them back in order but I dont recommend it because they are very delicate and you can make them worse or even damage the image sensor behind it! So let a pro do the job!!

(**)You should let some one with expertise have a look at it but if you don't think it is worth it and you are a kind of handy man, so, have fun yourself!

Be Good!.

Err 99 what is the propulam


Err 99 could mean several different things, such as... Memory Card, Lens or Lens contacts....
Here's what you can try:
Remove the memory card an enable "shooting with out memory card" and see if you still get the error. If it works your memory card is bad. Try another lens if you can. Clean the lens contacts with a pencil eraser (be careful not to get eraser dust in the camera body or in the lens). Worst case scenario is, Err 99 could be related to the shutter failing which would mean a trip to Canon.

Thank you for using Fixya!

My canon 20D autofocus doesn't work... can you tell me haw to do?? thanks..


Make sure your camera is set to Auto mode (top left knob). Check your lens and make sure it is switched to "auto" and not "manual"(sliding switch near base of lens). Make sure your lens can rotate and move without being obstructed. Clean the lens contact by removing the lens and use 99% alcohol or lens cleaner sparingly to clean off the metal contacts.
You can also check your viewfinder focus, it has a small dial upper right, that you can fine tune to focus to your own eyesight. If it is way off, your view will always appear to be out of focus.
Hope that helps.

Error 99 on screen cant take picture intermitant


Error 99 is known as Abnormal Mirror operation. Follow the link for help;EOS-1D Mark III/EOS-1Ds Mark III: AF Accuracy Adjustment
EOS-1D Mark III/EOS-1Ds Mark III: Abnormal Mirror Operation (Err 99)

It should be noted that the AF accuracy adjustment advisory is in addition to the previous EOS-1D Mark III AF mirror adjustment service notice. Free repairs are being offered for customers affected by the "Err 99" mirror problem, and Canon is also providing free AF accuracy checks and adjustments for customers experiencing problems with soft focus when using any but the central AF point.

Finally, Canon Japan has published a new manual entitled "EOS-1D Mark III AI Servo Auto Focus Manual" aimed at helping owners understand and get the most from their AF system.

My canon 20d stopped taking photos for no aparant reason. Kept getting error 99 and when I re insert the battery it starts clicking on it's own whether turned on or not. I sent it to Canon repair who...


If two cameras are doing it, I would suggest the contacts on your lens are dirty.

Try the following diagnosis steps for solving ERR 99 issues : -

To isolate the cause of the issue, 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 only 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 so, the camera may be faulty and requires a service. If it does not, then: -
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 faulty. Try a different card. If the message does not appear: -
1. Turn off the camera.
2. Clean the gold contacts on the lens by GENTLY rubbing them with a pencil eraser or soft cloth. Keeping the camera face pointing down, also clean the gold contacts on the camera, being 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 is faulty and should be serviced.

Error 99


I get error 99 sometimes on my 20 D but it?s usually to do with a lens that is attached. Sigma lens have been known to cause error's. If it's not that or dirty contact on the lens then it could be a more serious problem. I would at least check it out with a canon dealer/repair centre.
