New here, I am advanced amature level and have old assorted brand FD lenses for my old A1's and am considering going to Canon Rebel DSLR and using my old lenses with an adapter ring. I would like to get a full frame sensor, but can't afford it and am aware of the focal length differences. Has anyone had any practical experience with using FD adapter rings? I know there is another lens in the equation with the ring and all things considered I subscribe to the 12 inch rule of the best camera (the brain, not the equipment). I have read a lot of negative speculation about the FD adapter and would not like to hear it again, but is there any practical experience out there?
