|Because of the T2 universal screw mount socket I gave the lens I can use it with nearly every ever made cameras system.
Here it is mounted on a Contarex Bullseye.
The lens has now a diaphrame aperture and a helicoid.
It has now a higher speed because with the new aperture I used more of the lens surface, speed is f/6.5
Focus range is oo-0.5m
