My D-Reb is experiencing too many ERR#99s. Fortunately turning it off and on brings it back on line but it is annoying. It can go a 200+shots then several Err99s that it is a "pain".

Doesanyone any suggestions for sending the camera to Canon Service Centers. Are they quick on turnaround? Unfortunately the 1 yr warranty has expired.

I have not had any Err99's with eithermy DReb or 20Dand have not had to use Canon's service (and I've probably put a curse on myself for saying that:O).

Have you tried anything to troubleshoot it yourself?

1. Tried different lenses. Possibly a communications error between the body and the lens? Cleaned the lenses and bodys contacts?

2. Tried a different CF card.

3. Installing the latest version of firmware for the camera?

4. If they occur using flash, is it a Canon brand flash or other?

5. Is the battery still showing a good charge when the error occurs?

These are just some things that I might attempt before sending it in.

Good suggestion!!!

Error 99 is a general fault - most probably (5) the battery not having enough 'umph'... Try a new or another battery

Lens communication is Error 01, and CF is error 02... but a combination of both (or any other) could also result in error 99!

I believe I have the latest firmware 1.1.1. I can't seem to pinpoint the error. I use fresh batteries and I also used and removed my BG-E1. It happens with and without. I use a 18-55 kit lens, 17-40L, 28-135IS anda tamron 28-75 XR-DI. I use a 550EX Flash. It was happening very regularly then I used the Kit lens exclusively and went about 300 shots with only 1 err99. Switched to Tamron and went 100 shots but started happening again. I am beginning to suspect the Tamron. (very reluctant to use it with my 20D). I may try to stay with the Kit lens for a while to see if it clears up or seldom occurs. Interesting thing, I only need to switch it off and on to recover. Most people I read need to remove the battery.

Very reluctant to send to Canon but may have too. I need for it to be dependable on each shot.

I've heard if you change lenses while the camera is on could cause problems. so it is wise to turn the camera off before changing lenses. i don't have a dslr yet so i'm just repeating what i've heard and read.
