    I took pics yesterday-no problems.Today during a shoot I got the error 99 after shooting several pics. At home I removed, even switched to a different battery and the problem continues. It will shoot a few frames and error out and it doesn't seem to matter which setting is used.

I keep getting error 99 message


Error 99 is common error on Canon cameras. Make sure the battery is freshly charged. Take the battery out, the compact flash card out, and the attached lens off of the camera. Leave the camera set for a while for the capacitors to bleed off. Around a half hour would be good. Next re-insert the battery and push the shutter button as if you were taking a picture. If you get an Error 99 then, you can't fix the trouble and Canon will have to do it. If you do not get an error 99, power the camera off, insert the compact flash card, power the camera back on and press the shutter button again. If you get an Error 99, the trouble is in the compact flash card or its connector. Try a different card. If you do not get an Error 99, power the camera off, a lens on it, power the camera back up, then press the shutter button once again. If you do not see an Error 99, the problem is no longer in the camera. If you do see an Error 99, power the camera off and remove the lens. The problem is probably in the contacts on the camera or the lens. Clean the contacts by holding the camera carefully with the lens opening down so it will not allow dirt to get inside the camera. Take a cotton swab dipped in alcohol and clean the gold metal contacts well, Dry the contacts with a tissue. Next hold the lens with the contacts down and repeat the process on the contacts on the lens. Be very cautious not to allow lint, dust, or alcohol to get into the camera body or into the lens. Some people use a pencil eraser to clean the contacts but you have be very careful not to let particles enter the camera or lens. This should clear your trouble, if the camera passed the first step of troubleshooting.

Canon 40d will not take pictures


1) CF card in camera? Won't shoot without one

2) Does mirror go up?

3) Canon had a run of bad motors for this model - if mirror does not go up, then it is the mirror motor. If mirror goes up, shutter will not fire, press release again then the mirror goes down, the shutter motor is bad (same model motor). If mirror goes up, shutter fires, both blades travel together/no exposure, probably the shutter is bad.

Shoot 5 pictures and get error 99


There are over 40 different malfunctions that can cause an error 99 on a Canon 40D. The 2 that account for over 95% of the error 99's are either a bad shutter mechanism or a bad mirror driving motor. It takes special diagnostic software to determine the exact cause. Otherwise, a repairer just has to start replacing parts until the problem goes away.

I have a Canon 40D. When I press the shutter button, it has about a 5 second delay before taking the photo, on all modes. Help!!


You may have set the self timer, which is ordinarily used when you want to get into the picture yourself.

HI. Every I attempt to take a picture with my cam, I get a "Error 01" message. Please advise. Thank you


Err 01: LENS COMMUNICATION DESCRIPTION: This error occurs in the following conditions: When electronic communication with the lens cannot be established, after the EOS D300D is powered ON or when the shutter button is pressed halfway. When the lens diaphragm cannot be controlled during shutter release.

REMEDIAL MEASURE: Clean the electronic contacts on the lens with a clean, soft, dry cloth and check the mount interface switch on the body's lens mount for dirt or other damage. If this does not solve the problem, try another Canon EF lens or have the EOS EOS D300D examined by a qualified service technician. This error is similar to Error 84 on the D30.


rate me on this one...

thanks!

Canon 40d error 99


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.

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.
