SMC Multi-layer anti-reflection coating is applied to the surfaces of lens elements. This anti-reflection coating increases light transmission, eliminates flare and ghosting, and maintains color consistence among all lens models.
M A manual focus lens with automatic maximum aperture indexing, which is a mechanical system for coupling the lens to the camera's exposure system.

Manufacturer description #3

SMC Pentax-M 200mm f/4, although 1 1/2 stops slower than the 200mm f/2.5 lens, is even lighter than many conventional 100mm lenses, giving it fantastic maneuverability for its class. Both 200mm telephotos are splendid lenses for bringing medium-range images extremely close.
