I turned on the camera today fired off a shot, the shutter moved but no picture was taken, on the screen I get err 99, so after googling it I get dozens of different answers, most advise to remove the battery reinsert and try again, I've tried this but no joy, is it worth fixing or should I just buy a new one. The camera has taken nearly 100,000 frames so the shutter could be worn out?

I had this happen more than once with my 20D after firing off a long series of continuous shots. My "fix" was to remove and reinsert the battery, although on some occassions it took multiple removes/reinserts to correct the problem.

I'll try cleaning the contacts, I get the same problem with all my lens. I tried removing and reinserting the battery many times, it still doesn't work.

Just a thought, but are you using a battery grip by any chance? I've had this happen to me on my old 20D and I had to make sure each battery was taken out with all contacts removed before it worked again.

Yup using a battery grip, I've removed the grip cleaned the contacts in the battery slot, cleaned the contacts on the lens and on the mount, still the same error code. Guess it's time to bite the bullet and send it in for repair.

Yeah, I remember seeing somewhere that the expected shutter life on that body and a few hours is 100,000 clicks.

This happened on my 40D. I hit it(yes HIT) with my fist and then my knee right where the battery compartment is. It worked...go figure.

I had the same Error 99 on my Rebel xTi. My lenses would not auto focus and the pop up flash would not come up. I called Canon customer service and the service technician informed me this was a common problem caused by the contacts between the body and lens. (Didn't try to explain the problem with the flash yet.) Especially with 3rd party lens. Made sense, since I had a Tamron mounted to the body at the time. After removing all of the batteries, (even the small battery used to keep track of date/time) the lens and cleaning all the contacts. I put a Canon lens on and tried it. The camera still had problems with error 99. The service technician said I needed to send it in to have it repaired. My camera arrived back from the repair facility yesterday with a note that said "the upper cover was inoperative causing the error to be displayed." This would also explain why the flash would not work. Camera works fine now. Error 99 could be caused by several things, but It is most commonly caused by contacts between the body and lens. If cleaning the contacts do not help. You will need to send it in to have it serviced.
