Mamiya Sekor C 80mm f/1.9 Manual Focus Lens for 645 Review

The Mamiya Sekor C 80mm f/1.9 is a fast manual focus lens designed for the Mamiya 645 medium format system. As a standard lens for the format (roughly equivalent to a 50mm on full-frame), it delivers a classic field of view paired with an unusually wide f/1.9 maximum aperture. This makes it a strong choice for portrait work, low-light shooting, and achieving shallow depth of field with the creamy rendering medium format is known for.

This is a legacy product sold used through KEH, graded in Excellent condition with caps included. The 67mm filter thread is standard for the Sekor C lineup. Manual focus requires deliberate technique, but the combination of bright aperture and medium format tonality can yield distinctive results for photographers committed to the Mamiya 645 ecosystem. It occupies a sweet spot between speed and size within the Sekor C range.
