I have a Vivitar 80-200mm f/4.5 MC zoom and I’m trying to identify the mount so I can use it on a Micro Four Thirds camera. I first thought it might be Minolta SR/MD/MC, but my Minolta MD adapter does not fit. The bayonet tabs seem larger than the adapter opening, and this lens also has aperture levers that my Minolta-mount lens does not. Is this likely a Minolta SR mount, or a different mount entirely? If it isn’t Minolta, what adapter type should I be looking for for MFT?

I think this might be a Yashica/Contax mount.
It doesn't have the bite out of the correct side of the flange to be an SR.
It doesn't have ears so it's probably not F.
It's actually a bayonet so it's definitely not FL/FD.
It doesn't have a huge ramp on the back so it's not K.
It doesn't have a small ramp/shield on the back and shows no signs of an on-lens stopdown so it's probably not OM.
That kind of leaves Contax/Yashica by process of elimination given the era of mount design shown. And these look like they mayh match up with other pictures of that mount.

Generated from our catalog & community — verify before relying on it.
Based on the mount shape described, it’s probably not Minolta SR/MD/MC. The community answer points instead to Contax/Yashica (C/Y) mount by comparing the bayonet shape and rear linkage details and ruling out other common mounts.
So your MD adapter likely wasn’t falsely advertised—it probably fits genuine Minolta SR/MD/MC lenses, but this Vivitar appears to be in a different mount.
Vivitar made the same lens design in many mounts, so the name on the lens usually isn’t enough to identify it; the rear mount details matter.
If it is C/Y, you would need a Contax/Yashica-to-Micro Four Thirds adapter, not a Minolta MD-to-MFT adapter. Before buying, compare the rear mount carefully against reference photos of C/Y and Minolta SR mounts, or share a clear straight-on photo of the lens mount to confirm.
