LOLOL, film cameras, DSLR's, Canon focusing screens
The "fleet" of Mirror lenses. The two outside ones are both Sigma, the center is the Tamron Adaptall 500mm. The two Sigs are both 600mm. I think both were originally Minolta mount, which is too short a register for Canon. One of them I 'hacked' a junk lens to get the M42 rear piece and mounted it to the mirror, the other did the same thing with an import Canon EF adapter. I've never got the performance out of those two. Very difficult to deal with
