FED Industar-10 50mm f/3.5 M42 №4159 uralseller mod. for SLR and mirrorless

FED Industar-10 50mm f/3.5 M42 №4159 uralseller mod. for SLR and mirrorless Please note, this is an early uncoated version with a 10-blade aperture up to f/18 This lens was made in my workshop from an original FED lens for a rangefinder camera. The flange distance has been changed to 45.5mm, the bayonet mount has been changed to M42, and the minimum focusing distance has been changed to 0.5m. Therefore, this lens can be mounted on DSLR cameras and will focus from 0.5m to infinity. The lens has been tested on Pentax DSLR cameras; the mirror does not snag even when focusing to infinity. To mount it on a mirrorless camera, you will need a standard M42 adapter for your camera. Restored using modern lubricants. The glass is washed with Zeiss products inside and out.
