Re: Err 99

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

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.

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 D80 will not auto focus with any of my 3 Nikkor lenses. It will fire on auto focus when you manually focus while in that auto focus mode.


Press the AF button on the top of the camera (to the right of the window) to select an AF mode & make sure the M/A (Manual / Auto focus) switch on the lens set to "A"

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.

Focusing Problems


* Get AF off the shutter release and onto the * button using the custom function. * Use the center focus point only. Force yourself to pick what you want in focus, AF, then recompose and shoot, a habit far more effective than computer driven multiple AF points for just about everything. * AF performance degrades in low light no matter what camera you own. This is life. At least if you control the when/where of AF, you can try and choose high contrast points in the scene to focus on, points that will help mitigate the low light. * Not sure if this applies to you, but it does apply to many a pixel peeper...if something prints sharp at 8x10 or 11x14 then AF has succeeded even if it's a little off at 100% in Photoshop. AF is not perfect and the tolerances are not necessarily up to producing 40" enlargements, which is what 100% in Photoshop is. Having said that, in good lighting with good target contrast the AF on your 20D often will nail focus so perfectly that it will hold up even at 40".

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.
