Infinity focus preserved.
Can be installed on any camera with Sony E-mount.
Krasnogorsk-2 and 16-SP are 16mm camera, so image circle of it's lenses will not cover sensor Sony camera - vignetting will be quite large.
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.
Please refer to the last picture showing how to distinguish 16-SP lens. Krasnogorsk-2 lenses are very similar, but lugs width is 4mm instead of 10mm.
