Hi Gang......... I recently bought a Canon 10 D I have hanging around two old Canon lenses. One is an FD 50mm lens The other is a Sears zoom. (Hey don't blame me...they were given to me!) Can I mount these on the camera with out damaging any thing? I'm not sure why I would want to use these, but it would be good to know if I had the ability to do so. Russ R.E.
