The range of focus continues about ninety degrees beyond a full turn (approximately four hundred fifty degrees!) Marks in red paint indicate that closest focus is less than eight inches or twenty centimeters. I have verified this with a film camera and shall upload examples when they have been developed.
The rear of the lens has a standard thirty-nine/1.0 mm thread, however the lens does not match any flange focal distance without an adapter. I own adapters for M42 and Nikon F mounts, and I am aware of adapters for Exakta, Alpa, C-mount, and Arri-mount cameras.
