Mir 37 1B   (37mm f2.8)

     In preliminary testing I found the Mir 1B to be sharp, especially from f4, with low distortion and excellent color rendition.  Shadow detail is excellent. The lens is prone to flare so use a lens hood at all times.  Chromatic aberration is minimal.  Focusing is smooth and precise.  The aperture is almost circular and stepless, which is nice for shooting video.
