Pentax SMC Pentax 67 165mm f/2.8

Standard short-telephoto / portrait lens for the Pentax 67 system. In 35mm-equivalent terms, 165mm on 6×7 is roughly 80mm full-frame — a classic portrait length with characteristic compression and pleasing background separation. Used for portraiture (full-length and head-and-shoulders), short-tele landscape, and studio still life.

Distinct from the 165mm f/4 LS — this f/2.8 version uses the body's focal-plane shutter (no built-in shutter), which means it cannot exceed the body's 1/30 X-sync flash speed but offers a full stop more aperture (f/2.8 vs f/4) at the same focal length. Most Pentax 67 photographers own the f/2.8 focal-plane version for natural-light portraiture and the f/4 LS only if they specifically need fast flash sync.

Originally released alongside the Pentax 6×7 body in 1969 as the Super-Takumar 6×7 165mm f/2.8, later updated through SMC Takumar and SMC Pentax 67 coating generations. Mounts on the inner bayonet; 67mm filter thread.
