Mamiya 80mm f/2.8 Sekor D LS Autofocus Leaf Shutter Lens by Schneider-Kreuznach for Mamiya 645DF Body Only Review

The Mamiya 80mm f/2.8 Sekor D LS is a standard autofocus lens designed for Mamiya 645DF and compatible Phase One medium format bodies. Built by Schneider-Kreuznach, it features an integral leaf shutter, which enables flash sync at any shutter speed and quieter operation than focal-plane systems. The 80mm focal length serves as a versatile normal lens for medium format, suitable for portraiture, product work, and general-purpose shooting where the format's resolution and depth of field characteristics shine.

This is a used lens available through KEH with condition grades ranging from "excellent" to "bargain", priced at $214. As a standard prime in the 645 system, it offers a practical entry point for those building or expanding a Mamiya medium format kit, particularly for studio and controlled-environment work where leaf shutter capabilities are valuable.
