Question about Quantaray AF 70-300mm f/4.0-5.6 High Speed Auto Focus Zoom for Minolta
I have a Canon Rebel EOS camera. When I use my Quantaray 70-300mm zoom lens, it will not autofocus. It tries, but seems to struggle like the battery is weak. It twists back and forth, but can't go where it needs to. In manual focus, it will not allow the camera to take a picture. Instead, I get an Error 99. I cleaned the contacts on both the camera and lens with a clean pencil eraser, but nothing changed. I confirmed that the lens is the problem by using a Canon zoom lens, which functioned properly. With the information given, does this look like a major repair, and would it be cost effective to repair this aftermarket lens? (A new lens is between $125-$150).
The lens is for Minolta/Sony A mount and you are trying to use it on a canon body which has the contacts and mounting points in a different position so it isn't going to work as well as a lens with the correct mount for the body you are using if at all you will need to get the lens mount changed or an adapter built to allow the lens contacts to mate up in the correct order
will be cheaper to buy a camera body to fit the lens or a lens that fits the canon mount lens

That's good info. The trouble is that Quantaray makes lenses for different bodies. Your lens could be made for Minolta, Nikon, Canon or other. You may be able to find a universal adapter but first you need to know what mount that lens was originally made for. I recommend either taking the lens to a camera store or calling Quantaray to see if they can look up the mount using the serial number.

I bet they are not AF lenses. There are adapters that add the AF contacts to "fool" the camera but increase the zoom. You can get used lenses from many "on line" camera stores with warranties for a few months.
