So I got what I thought was a good deal for Nikon R10 that said it was untested, hoping to get lucky. Unfortunately there is some problems with the camera I need your help diagnosing to see if it's worth repairing or if I should just try to re-sell. When I put batteries in the camera, the only electrical piece that works is the slow zoom. No lights etc. The other issues is it looks like there are some kind of spots on the lens, but beneath the main glass. Is this worth repairing? Thanks all.
