Vintage 400mm f5.6 lens mount question

F6lover · 01-08-2018, 07:05 PM

Can anyone tell me if these prime lenses from the late 60's to early 70's have T2 threads on them or M42? I am referring to the lens itself before any adaptors are installed.
Thank you

The OP is more likely talking about the various third party lenses sold by Vivitar, Soligor etc.

Like this...

Vivitar TX / fixed / t-mount 400mm F5.6 Lens Reviews - Vivitar Lenses - Pentax Lens Review Database

So the answer is the mount varies from OEM to OEM...

No one can answer that without a specific example and a link to pictures or the ebay listing. Some will have M42, some will have T-mount and some might even have K-mount, or some other mount.
