Hopefully this thread is in the right place. If not, the mods are free to move it. I've recently started having problems with my Canon EOS Rebel XTi. I've had the camera for about 3 years, and loved it. Very few issues with it that haven't resolved themselves. However, on a recent trip with a friend out on a Family & Friends cruise aboard the USS George H.W. Bush, I began having a problem with the camera that didn't resolve itself. I began receiving an Error message Err99: Shooting is not possible. Turn the power switch to OFF and ON again or re-install the battery. (cooincidentally, this pic was taken with my A520, which is nearly destroyed, but still works flawlessly ) Along with this message, the shutter action felt "light". Normally, I'm used to the heavy "ka-chink" of the shutter opening and closing. But it seems when this error occurs, it seems that either the shutter isn't operating completely or something. Hard to explain unless you experience it. Or, I could just be imagining the whole thing. :mrgreen: Anyway, I of course tried turning the camera off and back on, replacing the battery with my backup, and swapping out memory cards. Same error. I would occassionally be able to take one or two photos, but then would receive the same message. Needless to say, I was slightly upset, as I really wanted to take photos of the air power demonstration. After a few hours, I attempted to use the camera again, and low and behold, it worked. I took a few photos, and had no problems. I even managed to shoot most of the air power demonstration. Then the camera started to fail again. So that took out my idea that it had something to do with the lens. :x Since then, the camera has sat in my camera bag, where it usually does, like a punished child. Although I'm not sure what it's done. I love my camera, and it's one of the few things that keeps me sane. I'm by no means a fantastic photographer, but I enjoy taking photos, so without it, I feel sad. Very, very sad. Has anyone else experienced this problem? Does it cost much to repair? Should I just look into buying another camera? I'm completely lost as to what could cause this problem, as I take good care of the camera, and can't seem to think of anything that may have happened to it to cause this. I'm confused, frustrated, and sad about the whole ordeal. Please help.
