Description — Pentax 200mm f/4 SMC A
The Pentax 645 200mm f/4 SMC A is a manual focus telephoto prime designed exclusively for the Pentax 645 medium format camera system. Built as a prime lens with a 200mm focal length, it occupies the telephoto range and is a strong candidate for portrait, nature, and detail-oriented photography where subject separation and reach are priorities. The maximum aperture of f/4 allows for solid light transmission while keeping the lens at a manageable 860g.
A 67mm filter thread means photographers can easily attach commonly available filters for creative or exposure control purposes. Because this is a legacy SMC A series lens, focusing is entirely manual, and there is no image stabilization system. Pairing this lens with a stable tripod or adequate shutter speed is advisable to achieve consistent results.
This lens mounts natively to Pentax 645 bodies, making it a natural fit for those already invested in the Pentax 645 ecosystem who want a dedicated telephoto prime option.
