Question about Quantaray AF 70-300mm f/4.0-5.6 High Speed Auto Focus Zoom for Minolta
When i turn on the cammera it gives me a error 99 code it tells me to turn off and then turn on the cammera it only does this when i use my 70-300 lens when i mess around i can get it to work only on manuale focase and when i take the picthure it is all black
Error 99 is one irritant in many Canon SLRs. In general, it means there is some problem with the contacts. So try cleaning the electrical contacts of the body and lens with a pencil eraser.Please take care to hold the camera upside down while doing this so that the residue does not fall inside. Also take out the battery and clean the contacts. Now re-attach everything and try taking the image. Also check if your lens has an aperture ring and aperture lock. If so, lock the aperture ring at the minimum aperture. If these do not solve the problem, try updating the firmware to the latest one.
