I'm wondering if it is possible to tell Vivitar TX and T4 mounts apart when they are on a lens. Anyone know?
Which mount - M42?
The first two are T4, the third is Tx
In this case you'd know because TX is the only one supporting P/ES - i.e. the SMC style M42.
I don't know if there was a TX non-ES M42 mount... probably there was, but maybe it would have been the Fuji open aperture style or something.
If it is possible to pop the mount off, it will say which it is on the mount and on the lens, but you know that already
