Pentax SMC Pentax 67 200mm f/4

Medium telephoto lens for the Pentax 67 system. In 35mm-equivalent terms, 200mm on 6×7 corresponds to roughly 100mm full-frame — a long portrait / short-tele focal length that bridges the 165mm portrait and 300mm telephoto positions. Used for distant portraiture, environmental portraits with significant background compression, mid-distance sports and wildlife, and short-tele landscape work.

Originally released as the Super-Takumar 6×7 200mm f/4 with the Pentax 6×7 body in 1969, updated through SMC Takumar and SMC Pentax 67 coating generations. The f/4 maximum aperture is one stop slower than the 165mm f/2.8 — typical for a focal-length jump of this size in medium format optics.

Mounts on the inner bayonet (Pentax 67 lenses ≤300mm use inner). 67mm filter thread, matching most other Pentax 67 lenses for filter-set sharing. The lens is hand-holdable in good light at 1/250 or faster (mirror-vibration safe zone) but rewards tripod use with mirror-lockup at slower speeds.
