Screw Mount (Praktica/Pentax M42) Cameras

"The most successful lens mount, in terms of economy and popularity", Thomas Tomosy [3].

These pages were created to be a source of information about screw mount cameras. Being just a user of the screw mount cameras, not a collector, I tried to concentrate on the photographic features of the many screw mount cameras available. Unfortunately, my knowledge of the subject is limited and many information on the pages may be incorrect, so don't bet your life on it. I also hope that many people who used or use different screw mount equipment will share their knowledge of it.
