Mamiya Sekor C 70mm f/2.8 E Manual Focus Lens for 645 Review

The Mamiya Sekor C 70mm f/2.8 E is a manual focus standard lens for the Mamiya 645 medium format system, typically available on the used market through resellers like KEH. At 70mm, it offers a slightly wider field of view than the classic 80mm normal lens for 645, making it a versatile option for portraiture, street photography, and general use. The f/2.8 maximum aperture provides decent low-light capability and shallow depth of field control for medium format work.

This lens is part of the Sekor C lineup, known for solid build quality and reliable optical performance across the Mamiya 645 ecosystem. As a legacy manual focus lens, it requires familiarity with manual exposure and focusing techniques, but medium format shooters often prefer the deliberate pace this encourages. With an MSRP around $229 for used copies in excellent condition, it sits in the affordable range for medium format glass, appealing to film photographers looking to build out a 645 kit without breaking the bank.
