Thread mount (Praktica/Pentax M42) Cameras

- Taken from long gone website -

These pages were created to be a source of information about thread mount cameras. Being just a user of the thread mount cameras, not a collector, I tried to concentrate on the photographic features of the many thread 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 thread mount equipment will share their knowledge of it.

The information in these pages comes mostly from the books listed in the bibliography section.
The following notation was used:
?? - have no idea
? or (?) - I think so, but not sure
no marks - It must be as written, but may be wrong.
