When I try to take a picture I get an error 99 message. Shooting is not possible turn off power switch or remove battery

Hi there :the Error 99 is a comunication error between camera body and lens .are you using Canon lens?Try the camera body with a/another Canon lens in Camera body and try the lens on another Canon camera.With this troubleshoting you can know if the camera body is failing or lens is failing.I hope this information will help you.

hi the err 99 usually stands for shutter problem. however, there are several different causes. The first is defective shutter unit, second is defective power diaphragm unit in lens, and main PCB defective. You have to bring to your local repair shop. they would charge you around $65 to $235 depend on what it really cause problem. you can verify lens or body problem. try to operate without lens if still see err 99 when you push button. then it is body problem... Good luck with you...

It could be several problems. One is a bad contact between lens and camera body, clean the contacts , check for damage and try another lens if you have one. Try another memory card. Another problem could be with the shutter which would need the camera to be repaired by canon.

1.Remove the battery, lens and CF card. Allow the camera to sit without power for 20 minutes and then reinsert a fully charged battery.
2.Turn the camera on and push the shutter button as if you were taking a picture.
3. If you don't get the error message reattach the lens and insert the CF card.
4. Check the below canon eos 400d service manual link:

it will help you to save a lot of money
Hope it helps, Thanks

I did some digging and found that this error is most often a lens communication error. Are you, by chance using a non-Canon lens?

Try the following:

1. Remove the lens and take a picture without any lens on. If you get an ERR 99, then it is a camera issue and you will need to contact Canon for further troubleshooting or repair (ie. not the lens).
2. If you do not get the error with the lens off, try it with a Canon lens or any other lens. If no error, it is a problem with the original lens.
3. If the error occurs on both lenses, clean the lens contacts both on the lens and the camera (refer to your manual).

Hope this helps.
