I used to shoot lots of film slides and print 35mm and 2 1/4" Sq 35mm Canon F1, A1, AE1/P 21/4" Hasselblad.

Not done any film in over 2 plus years, use to do color printing too not black and white b&w is much harder to make a good print than color

If you need any repair done on your film cameras let me know I have a friend that is a master camera mechanic, I have lots of canon A series cameras to sell if you are interested
