Mamiya-Sekor 80mm f/2.8 Seikosha-S Lens for TLR, Chrome Review

The Mamiya-Sekor 80mm f/2.8 Seikosha-S is a classic twin-lens reflex lens designed for Mamiya TLR cameras, now available as a used item in excellent-plus condition from KEH. This 80mm focal length is the standard for medium format TLR shooting, offering a natural field of view well-suited to portraiture, street photography, and general-purpose work. The f/2.8 maximum aperture provides decent speed for its era, and the Seikosha-S leaf shutter is known for its quiet operation and reliability. At $211, this represents an entry point into medium format film photography for those already invested in the Mamiya TLR system or looking to start with a reputable vintage platform. The chrome finish and excellent-plus grading suggest this example has been well-maintained.
