Schneider-Kreuznach 150mm f/3.5 LS Leaf Shutter Lens for Mamiya 645DF Series Bodies Review

The Schneider-Kreuznach 150mm f/3.5 LS is a leaf-shutter medium format lens designed for Mamiya 645DF series digital backs. At 150mm, it delivers a portrait-length focal length on the 645 platform with the added benefit of an integrated leaf shutter, enabling high-speed flash sync at any shutter speed, a major advantage for studio and location portraiture. Schneider-Kreuznach is known for optical quality, and this lens fits into the professional tier of the Mamiya 645 system. The f/3.5 maximum aperture is typical for medium format glass of this focal length, offering a good balance between speed, size, and cost. This used example comes from KEH in Excellent Plus condition with caps and hood, suggesting minimal wear and full functionality. At $667, it represents the used market for a professional tool aimed at shooters who already own a 645DF body and need a reliable, leaf-shutter portrait lens.
