(none) 28mm F/2.8 Auto M42 Screw Mount Manual Focus Lens Review

This is a vintage 28mm f/2.8 manual focus prime lens with the M42 screw mount, a legacy mount standard that enjoyed widespread use in the 1960s through the 1980s. The M42 mount can be adapted to most modern mirrorless camera systems with inexpensive adapters, making it an affordable entry point for experimenting with manual focus glass. At 28mm, it offers a moderately wide field of view suitable for street photography, environmental portraits, and travel shooting. The f/2.8 maximum aperture provides a reasonable balance between light gathering and compact size, though it won't deliver the subject isolation of faster primes.

This particular copy is sold in bargain condition by KEH, meaning it shows significant cosmetic wear and may have optical imperfections like cleaning marks, dust, or light haze. At this price point, it's a low-risk way to explore vintage glass and manual focus technique, but expectations should be set accordingly. Image quality will likely be softer than modern lenses, especially wide open and at the edges, and coatings may be less effective at controlling flare. Build quality and optical performance will vary depending on the original manufacturer, which is unspecified here.
