Please help me identify this lens mount

[xkaes]

Here are two lens mounts. The one on the right is a Minolta mount. The one on the left is unknown to me -- and I've had no luck searching the WEB:

The one on the left looks a lot like Minolta, but Minolta has the aperture pin on the inside of the bayonet while the one on the left has it on the outside.

I know the one on the left is not Nikon, Canon, Miranda, or Petri. Anyone know what it is?????

Rolleiflex 35 mm SLR mount?

Thanks for the tip. I know nothing about Rollei SLR cameras -- other than they made some great lenses.

It looks like a Rollei QBM 2-pin mount -- they also made a 1-pin QBM mount.

All credit to Google -- I just started image searching for 35 mm SLRs I was aware of that weren't on your "it's not this" list.

The one on the right says it is a Minolta mount, left one looks like Minolta also. With no stop down linkage maybe for a pre set lens?

The one on the right says it is a Minolta mount, left one looks like Minolta also.

The left one then got a smaller inner diameter and the actuator at different position and with axial instead of lateral movement.

The left one is not a Minolta mount. It is a 2-pin Rollei QBM mount.
