Question about Cameras
The lens contacts are dirty. Get a
pencil with an eraser on the end, just a regular old pencil with a 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 do-able: just hold camera so lens opening points down so no gunk falls in. Erase lightly. Use a lens cloth and dab at the contacts rather than blow them so as not to blow the erasings inside the camera.
Do this to each of the three lenses just to be sure.
1. Turn off the camera.
2. Clean the lens contacts by gently rubbing them with a pencil eraser or soft cloth. Be careful that you do not let any debris fall into the camera body.
3. Reattach your lens.
4. Turn on the camera.
5. Depress the shutter button as you would to take a picture.
If the “ERR 99′ message only appears when one particular lens is attached, then that lens should be examined by a service technician.
If you see the “ERR 99′ with a different Canon lens attached, then the camera should be serviced.
