Cannon Eos 400D Err 99? - Cameras

What kind of error? Err 99?
You mention DS 126151, that's the model number. This camera is mostly know as Canon EOS Rebel XTi? Also known as the EOS 400D or EOS Kiss Digital X.
If you are getting a Err 99 while shooting, try any other lens that will fit on your Canon. In most cases the aperture will become defect in these lenses. Not worth repairing if you ask me. One thing you could do, is shoot only at its maximum aperture. So that'll be F4.0 at 70mm and F5.6 at 300mm. That might work, but that might not be suitable in every situation.

Usual cause is bad shutter

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.
Have a good one!

Make sure your firmware is up to date. The current version is 1.09 which did address a problem with live view that could cause error 99.
Here's the link http://web.canon.jp/imaging/eosd/firm-e/eosdigital4/firmware.html


Also try removing your lens and putting it back on. Sometimes it is a bad connections between the body and lens that can cause this error.
