The Pentax SMC 6x7 45mm f/4 is a wide-angle lens built for the Pentax 6x7 medium format system, covering street photography, environmental portraits, and landscape work with the distinctive rendering that only large-format film can deliver.
Pentax 6x7 wide-angle lens — what you're getting
This is a dedicated medium format lens — not a 35mm or digital optic. The SMC (Super Multi Coating) designation means Pentax applied their multi-layer anti-reflective coating to reduce flare and improve contrast, which matters a lot when you're shooting wide in bright or backlit conditions. On the Pentax 6x7 body, 45mm sits firmly in wide-angle territory, giving you an expansive field of view well suited to architectural and landscape shooting.
Buying this second-hand is one of the few realistic ways to shoot medium format wide-angle without paying new-old-stock prices. Every used copy sold here comes with a minimum 12 months warranty.
Compatibility
This lens is designed for the Pentax 6x7 medium format film system. It uses the dedicated Pentax 6x7 bayonet mount and is not compatible with 35mm or digital Pentax bodies without specialist adapters. Third-party adapters do exist for mirrorless systems, though coverage and vignetting will vary.
Who is this for?
Film photographers shooting with a Pentax 6x7 or 67 body who want a wide-angle option for street, environmental portraits, or landscape work. If you shoot 120 film and want that expansive, immersive rendering that medium format wide-angles are known for, this lens is a practical choice. It's also a solid pick for anyone transitioning from a 35mm kit and looking to go bigger without switching systems entirely. Take a look at our range of used lenses too. You'll find camera accessories in our range as well.
