I have a 1 year old XTi, and i'm currently traveling in India. I went to use the camera at night and I get err 99 only when using the flash. This happens with my 28-135IS and 50mm prime.

Any ideas? will i need to replace the body or does canon cover this under warranty after a year? I can't call them up or go to a canon store for a couple weeks.

Maybe I should just pick up an external flash

Is it just with the flash that you get the error? Tried whiping down the contact points? Worth a shot.

Happens only with the flash popped up. Cleaned the lens contacts as well.

I took off the lens, and tried clicking with the flash open. Says Busy with the flash symbol and then err 99. This is like the BSOD of windows :o

I got this on my old Rebel. The little switches inside the flash started sticking so the camera thought something was obstructing the flash. It was solved by cleaning and then lubricating the little switches. Not sure what they look like on the XTi but on the Rebel they were 2 little plastic pegs either side of the popup flash.

For a quick fix you can pop up the flash, turn the camera off and then on again and it should work fine.
