Pentax SMC Pentax 67 55mm f/4

Wide AngleMount: Pentax 6755mmf/4 – f/32
Introduced: 1969

SMC Pentax 67 55mm f/4 is the wide-angle prime for the Pentax 67 system — equivalent to roughly a 28mm field of view in 35mm terms on the 6×7 cm format. The 55mm focal length is standard wide for 6×7 (alongside the 45mm super-wide and the 75mm wide-normal). SMC denotes Super-Multi-Coating, Pentax's high-contrast lens coating system.

Use case + rendering

The 55mm f/4 is the landscape + interior + environmental wide Pentax 67 lens. Sharp by f/8, very sharp by f/11 — typical retrofocus-wide behavior where stopping down brings up corners more than centers. SMC multi-coating handles flare and backlight well; reasonable for B&W landscape with strong sky elements.

The 55mm sits between the 45mm super-wide (for tighter spaces and dramatic perspective) and the 75mm wide-normal (for general-purpose work). Many Pentax 67 photographers use the 55mm as their primary wide because it covers most landscape needs without the perspective extremes of the 45mm.
