Cleaning the gold connectors between the lens and camera normally seems to stop it for me.
ERR 99 is to do with the contacts controling aperture on lenses, more frequently occuring whilst using 3rd party lenses. Is your mate using a Sigma or similar (other than Canon) lens.

hi all, wonder if anyone can help a mate of mine has a canon 350d but he keeps getting "error 99" come up on the screen so he cant use the camera, has anyone got any ideas,told him should have got [S1]nikon[/S1]
My mate had this with a Canon lens but it was an older lens, he could take one shot then would get the error. binned the lens and got a 70-300IS and all is well, all his other lenses worked except that really old one.
