Question about Canon EOS 40D Digital Camera

1 Answer

Error 99 keeps appearing on my Canon 40D. I changed the battery and that worked for one shot and then back to error 99. Camera will now not operate. Have had it over a year and no problems until now. Could it have been because of shooting quite a lot recently in the "burst" mode? Thanks Jim R

An error 99 on Canons indicates a lens issue, do you have a second lens you could try? If not try this solution from Richard's Notes.

My canon 30D comes up with err 99 pleas help


My first stab at guessing would be the older-style lens can't communicate to the 40D, resulting in a read error. Any problem when using other newer lenses?

Try doing a full format of the card using the camera - don't just delete all images. Then re-zero the shot count. See if that helps.

Got Error 99 on my 40D. Have done all the obvious: remove battery, replace battery, check lenses, SD cards. Have talked with several people who tell me it's "common" with 40D. Any assistance you...


Welcome to Fixya
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.

Thanks!

My Canon 40D suddenly came down with the dreaded Error 99 for no apparent reason. I have tried all the usual, battery, memory card, lens, but no luck. Even on the bulb setting the shutter won't stay open....

Eos 40d error 99


Error 99 can mean many things. Have you installed the latest firmware for the camera (version 1.1.1)? If you don't have, download it here (for equipment purchased in USA or Puerto Rico):

http://web.canon.jp/imaging/eosd/eos40d/eos40d-firmware-e.html

If you have the latest firmware, try this:

  1. Switch off the camera and remove the CF card and battery
  2. Keep the camera idle for 30 min
  3. Clean all the contacts of the camera (battery contacts, lens contacts etc) with an eraser. Do this keeping the camera facing down so that no debris fall into the camera.
  4. Attach the lens and insert the battery.
  5. Switch on the camera
  6. Insert the CF card
  7. If the error persists, format the card again
  8. If this does not work, try using another CF card.

Canon EOS 40D - Error 99


The 40D is not a water resistant camera body. It is VERY important to keep it from getting wet, even "just a little mist".

The first thing you need to do is remove the battery, and the lens. Then let the camera dry out in a warm and not-humid location for a few days. Do NOT try to power it up until you are 100% certain that it is dry.

The water at Sea World has salt in it. You may have salt in an electrical connection, even after the water has dried. You can try using a swab very lightly moistened with rubbing alcohol to dry the connections you can reach - the battery connection and the connections between the camera body and the lens (clean the connections on the lens as well as the camera body). Then let the camera dry AGAIN for at least 24 hours before you reattach the lens and insert the battery.

If these do not fix the camera then you will need to send it in to Canon for cleaning and refurbishing.

Err99 40d canon body only


Try the following diagnosis steps: -

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 Code on 5 month old Canon 40D


error 99 can be several things. Try the following. Check that the contacts on the lens housing are clean if not clean them with a swab of denatured alcohol available at walmart. also if there is extremely cold weather your shutter could be creating the error. Try using a blow dryer and on the warm setting warm up the camera with the lens off. Blow around the mirror area. I know it sounds silly but it has worked in the past. Good luck.
