My 18-month old Canon Rebel XTi (400D) started giving me the dreaded (Err99) error message about a week ago. I was taking some shots and suddenly the edges of the viewfinder screen went dark and the camera refused to shoot. The screen on the back said I had "Err99" and I should shut the camera down, remove the battery, put it back in and turn the camera back on. At first, I could get one or two shots before this happened, but finally, the camera refused to shoot at all. The shutter would go, but no image would be recorded. I was shooting with my EF-S 17-85MM f4-5.6 IS USM, but I put my EF 70-300mm f/4-5.6 IS USM on and the problem still happened. This tells me that the problem is in the camera body, not the lenses.
Searching the web, I found some suggestions on how to fix the underlying problem. I removed the battery and CF card, let the camera sit for 20 minutes and then put them back in and tried it. This didn't fix it. Then, I cleaned the lens contact points on both the camera body and the lenses with a white eraser. This seemed to fix the problem - the camera shot just fine. However, it now occurs to me that I tested it in a dimly lit room, rather than outdoors.
On Sunday, I was all lined up to get a nice shot of a DHC Beaver and it happened again - Err99. I tried the other lens and still it happened. I borrowed a pencil eraser and cleaned the contacts. Still I got Err99. I was on a ferry boat at the time and was so frustrated about missing the shot that I felt like throwing the damn camera overboard. I had trusted the camera and didn't even have a backup (my PowerShot S3 IS) with me.
Today, someone at work suggested resetting all of the camera settings back to default. This seemed to work and the camera shoots fine, both in dimly lit situations and outdoors in the sun. However, now I don't trust the beast. The question is: is it really fixed? Have other people out there had experience with Err99?

I've had this happen twice. The first time nothing worked and I had to send it back to Canon and they replaced my shutter for free and returned it to me. That was half a year ago.
Recently it happened again. I was shooting when all of a sudden I got the error. It would take two shots then give me the error again after I turned it off and on. Finally I got frustrated and smacked the camera with my hand. The error went away!! Two hours later it came back, after which I hit it with my knee where the battery goes in and it went away again. At this point I don't trust the camera either....

Try to upgrade firmware. Maybe they solved this problem in latest issue. You can find it at Canon's website. But following users that have problem with err99 this is shutter's fault at 99% and lens problem in 1%. As the lens problem is by user's fault that shutter's malfunction caused by manufacturer.
I thought about replacing my 350D by new 40D but now I will keep my old camera .

An update: when I got home from work, I tested the camera again and got Err99.
Quoting Clickhappy (Reply 1): David - I would try reading through the Canon DSLR forums at dpreview.com:
Thanks - I checked them out and tried some of the remedies, but still I get Err99.

This sounds like a sticky shutter. Mine might have the same problem. I felt tempted to smack it, but restrained myself.
One thing I should mention was that I know I have taken over 20,000 exposures with it and the count might even be 10,000 higher.
