Vivitar 28mm f/2.5 Auto EE Lens For Konica Review

The Vivitar 28mm f/2.5 Auto EE is a vintage manual-focus wide-angle prime designed for Konica's discontinued SLR mount system. At $32 in excellent used condition from KEH, it represents an affordable entry point for anyone shooting Konica film cameras or adapting legacy glass to mirrorless bodies. The f/2.5 maximum aperture is modest by modern standards but typical for compact wide-angles of this era, offering decent low-light performance and some subject isolation on APS-C sensors.

This is a straightforward mechanical lens with automatic exposure coupling for compatible Konica bodies. Build quality reflects Vivitar's third-party lens production of the period, which ranged from workmanlike to surprisingly solid depending on the manufacturing partner. Optical performance will favor those who appreciate the character of 1970s and 1980s glass: expect good center sharpness wide open with softer corners, moderate flare resistance, and color rendering that leans warm. It's best suited for experimental shooters, film enthusiasts with Konica gear, or budget-conscious adapters willing to work with manual focus and modest specs.
