With a CYCLOP 85mm f1.5.

This lens as no aperture blades. So I made a few different cardboard cut-outs to fit on the front of the lens, to enable the lens to "stop-down". Including one with a square aperture.

A CYCLOP 85mm f1.5, M42 lens, on a H3T-1 night vision scope.

The CYCLOP has a very similar optical design as the Helios 40, but without aperture blades. So is it a one-eyed bokeh monster king?
