Pentax 67 SMC Takumar 55mm f/4 Ver 2
Summary
The SMC Pentax 67 55mm f/4 is a wide-angle prime introduced in 1986 for the Pentax 6×7 medium format system, offering a 65° horizontal field of view—roughly equivalent to a 28mm lens on 35mm film. It’s the third and most refined version of Pentax’s 55mm lineup, known for its improved optical formula and compact design compared to earlier f/3.5 variants. It features an 8-element - 7-group optical design, Super Multi-Coating (SMC), and an 8-blade automatic diaphragm. The lens stops down to f/22, focuses as close as 35cm, and delivers 0.24× magnification. It uses a 77mm filter thread, weighs 725g, and measures 92.5 × 78.5mm. It includes a PH-SA 77 mm hood, clip-on cap, and was often paired with a dedicated hard case. The lens has no “A” setting, so it’s best used in manual or aperture-priority modes.
Came in two variants with different specs. See other version.
