Vivitar 28mm F/2.5 Auto M42 Screw Mount Manual Focus Lens Review

The Vivitar 28mm F/2.5 Auto is a legacy manual focus lens with M42 screw mount threading, making it compatible with a wide range of vintage and adapted camera bodies. At $51 on the used market, it offers an affordable entry point for shooters interested in experimenting with manual glass or building out a set of classic wide-angle optics. The F/2.5 maximum aperture is reasonably fast for a 28mm focal length from this era, providing decent low-light capability and shallow depth of field control for a wide lens.

This is vintage glass sold in used condition, so expect variability in optical and mechanical performance depending on the specific copy. M42 mount lenses require an adapter for modern mirrorless systems or older film SLRs with the appropriate mount. The 28mm focal length works well for street photography, environmental portraiture, and documentary work, especially on APS-C sensors where it provides a roughly 42mm equivalent field of view.
