Pentax smc Pentax-M 20mm f/4
Pentax smc Pentax-M 20mm f/4 is a compact manual-focus wide-angle prime for Pentax K-mount film SLRs. As part of the M-series, it is small, metal-bodied and very straightforward to use, with manual aperture control and a conventional mechanical feel that suits classic Pentax bodies and adapters. The 20mm field of view gives an obvious wide perspective for landscapes, interiors and street work, while the f/4 maximum aperture keeps the lens relatively small rather than chasing speed. Image character is typically that of a well-made older prime: strong central sharpness when stopped down, with the usual limitations of vintage wide angles such as edge softness wide open and some flare if used into bright light. It is a good match for users who value a tiny, fully manual lens and do not need autofocus or modern electronic communication. On the used market, check for smooth and accurate focus movement, clean aperture blades, oil on the blades, haze or fungus inside the elements, excessive dust, and wear to the K-mount contacts and bayonet surfaces.
