ShutterFile: A Reference File for Classic Cameras and Lenses

shutterfile.com Observed source

Editorial interest 78/100 Selection signal · not a rating of the site

A compact reference site for classic camera lenses, with mount families, production-year guidance, model files, and pre-purchase checks.

Landing page captured for the 2026-09-14 issue.

Field notes

The site groups classic-lens information by mount family and currently lists 16 M42 references. Its dating system treats production years as catalog-era approximations, with “c.” used to signal that limitation. Other mount families—including Canon FD, Nikon F pre-AI, Minolta MC / MD, Olympus OM, and Pentax K—are labeled as planned rather than presented as complete. The project also discloses eBay affiliate participation while keeping prices and live listings out of the reference.
