Originally posted by stevewig I am aware of at least three variations of the MIR 37mm lens (MIR 1, MIR B and MIR Sh). Does anybody know the difference between these lenses? I own the MIR B and the MIR Sh and the Sh appears to be somewhat sharper than the B?
MIR-1 8- blades in aperture, first edition M39
MIR-1Sh for school, "shkolniy"
MIR-1C with central gate.
MIR-1A with A-adaptor can be connected to different mounts.
MIR-1 Auto for Kiev-10, 15.
MIR-1B is more late revision with 10- blades in aperture, M42 B - means VOMZ ( made in Vologda city)
