What lens is it on? It looks like the original K mount to me.

This is my lens

MetalUndivided · 07-26-2019, 04:09 AM

Yeah, it appears to be the Sigma Zoom-K 100-200 with the Pentax K mount.

Sorry, but it is a Nikon mount, there is a small tab that engages the metering for the old Nikon AI metering

alpheios · 07-26-2019, 04:33 AM

Yes it’s Nikon. Besides the tab that Lowell mentioned there is no notch for the locking pin where it should be for K mount.

Negatory folks - thats OM, the square button on the side is the giveaway (there's usually two, one is lens release, the other is stop down).

Looks like we are in agreement.

Push in on those two black buttons on the lens mount and the lens will stop down. Olympus OM.

But from the first photo there is only one black tab (not a button).

Compare to photo of OM mount (photo from SLR Lens Mount Identification Guide )

(note lack of locking pin slot)

**marcusBMG** · 07-27-2019, 07:26 AM

I'm sticking with OM ...
Note the small lens lock stop screw/stud at almost quarter after (also distinctive OM), and its positional relationship to the long slot and the aperture lever. Then compare with
