Schneider-Kreuznach 35mm f/2.8 Curtagon Manual Focus M42 Screw Mount Lens Review

The Schneider-Kreuznach 35mm f/2.8 Curtagon is a vintage manual focus lens with an M42 screw mount, a classic thread standard that enjoyed wide adoption during the film era. Schneider-Kreuznach built a strong reputation for optical quality in the mid-20th century, and the Curtagon line was known for delivering respectable sharpness and character at moderate apertures. This particular listing is a used unit in bargain condition from KEH, which typically means visible cosmetic wear and possibly some optical imperfections, though it should remain functionally usable.

At 35mm and f/2.8, this lens offers a mild wide angle on full-frame and a near-normal field of view on APS-C sensors. M42 mount lenses can be adapted to many modern mirrorless systems with inexpensive adapters, making them accessible for enthusiasts interested in manual focus shooting or vintage rendering. However, expect slower handling, no electronic communication with the camera body, and potential optical quirks common to older designs. The $157 asking price positions it as an affordable entry into legacy glass, though condition and optical performance will vary with bargain-grade inventory.
