Canon EOS 620 Film Camera

This camera is the 'professional' version of the 1st EOS camera, the Canon EOS 650. Of the different features on the two cameras, it's really hard to see what makes one a 'pro' and the other not. In any case, the on-line value of these bodies in good working condition is very low (usually well under $50) and either one makes a super film back up for your EOS digital camera. With cheap adapters you can use virtually any of the manual focus Nikon, screw-mount Pentax (i.e. M42x1), screw mount Leica (M39), and many other lenses in manual mode. Ironically, the one thing that it doesn't make sense to use are the earlier Canon FD lenses that do require optical elements in the adapter to focus to infinity.
