Infinity focus preserved.
Can be installed on any camera with MFT mount.
Krasnogorsk-2 and 16-SP are 16mm camera, so image circle of it's lenses covers sensor of Black Magic Pocket Cinema Camera with minor vignetting.
You can install this adapter on APS-C cameras as well, but lenses will vignette quite much on larger sensor.
Only difference between K-2 and 16-SP mounts is wider bayonet lugs on 16-SP. This is our universal adapter that will fit both types of lenses.
This adapter version has a bayonette lock ring for quick change of lenses. If you have only one lens, you can purchase a cheaper version with set screws.
