This version of Mir-1 is significantly different from all the others. Firstly, the focuser has a completely different, highly complicated design due to which the minimum focusing distance is reduced from 70cm to 24mm. In addition, the lens has a complex aperture structure similar to the Helios-40 aperture. The aperture blades and glass ends have a black matte coating that eliminates light reflection.
This lens is workshop serviced with a modern quality lubricant. Works better than new.
Great for macro and landscape photography.
