Question about Canon EOS 400D / Rebel XTi Digital Camera
This is what the people at the canon tech support say to do for error 99
read this!! :)
The guy at tech support listened and then told me that the lens contacts were dirty and to get a pencil with an eraser on the end, just a regular old pencil with a red rubber eraser. Detach the lens from the camera, hold it so that the lens’ gold contacts are pointing down and lightly erase their exposed surface, cleaning them of any hand oil that might have gotten on them.
Do the same thing with the gold contacts inside the camera body. This is a bit harder but it’s doable: just hold camera so lens opening points down so no gunk falls in. Erase lightly. I used a lens cloth and dabbed at the contacts rather than blow them so as not to blow the erasings inside the camera.
I did this to each of my three lenses just to be sure. Lo and behold, it worked
hope this works for you!!!! have a nice day!! :) :)

Err 99 is moisture or dew inside the camera. try drying various contact points such as the hot shoe

on these models the 99 code is generic, and can mean a bunch of different errors, but usually it is dirty contacts. It can be on the battery, or more likely between the lens and camera body.
Check out this link here, there are a lot of good things to try.
Good luck. And don't listen to the comments that Canon is bad, I have had Canon's for years, and they are great cameras!
