Identifying K3 Lens Mount

[Akim Dolinsky]

Hello,
I got a K3 Meteor lens, thought it's m42 and it's not(bought an adapter for m42). I was told it's the bayonet version.
Since it has those two "teeth" on the mount. From reading around it seems like it could be SP16 mount.
I want know for sure because I want to buy an adapter to mount on Blackmagic Pocket Cinema Camera(MFT mount).

Can anyone tell me what mount is for sure?

As far as I know, it seems that K3 (bayonet) and  SP16 is same mount and some of SP16 lenses can fit on K3, especially 10mm.

by the way, hard to find. Otherwise, you got 12.5/20 and 50mm primes for K3.

The images look like the standard Krasnogork bayonet mount. So should fit the bayonet mount K3 easily.

As of the SP16 lenses vs. Krasnogorsk mount, the SP16 mount has larger flanges and the lenses may need modification to fit the Krasnogorsk cameras even when the FFD is approximately the same. So you CAN make them work with Krasnogorsk cameras but don't expect them to work right away without any modifications. For example my 10mm T3.1 needed grinding half of the bayonet flanges away to fit the lens to the K2. Took about an hour with Dremel so it is not just "put the lens on the camera and go shooting" even when you can make them work relatively easily
