Strange lens mount Help ID

Riggson · 11-25-2017, 01:20 PM

Hello all
I recently be bought a 200mm Vemar prime lens on auction and on delivery found it was an Exact K mount rather than a Pentax K. After unscrewing the adapter I expected to find a T or M42 thread but instead found (as near as I can measure) a 46mm screw mount. Any info about the larger size screw mount? As I only gave $5.00 for the lens I'm more curious than anything else, but if there were an adapter it might be fun to try it out. If there's any interest I'll take some pics & post later.
Thanks, Robert

Sounds like an early Tokina interchangeable-mount system. 47mm T-Thread?

Thanks, looks like that could be it. One of the posts mentioned a Vemar lens with a T47 mount. All I could find on Google were references to a Komura Unidapter system but very little hard info about it.
