Vivitar Vivitar 28mm f2 Heritage

Overview

The Vivitar 28mm f/2 was one of many 28mm wide-angles sold under the Vivitar name, which contracted out lens production to a range of Japanese optical houses including Tokina, Cosina, Kino Precision (Kiron), and Komine. This particular fast f/2 version was made by Kino Optical (Kiron) and is identified by serial numbers beginning with 22xxxxx (the Komine builds carry 28xxxxx serials, Cosinas 9xxxx, and Tokinas 17xxx). The only established community term tied to these lenses is 'Kiron,' the Kino Precision house brand that denotes the maker rather than a nickname. According to the reviews, there are two notable production eras: earlier examples featured a long 260-degree focus throw, a double helicoid with floating elements (the front and rear optical units moving differently), and an 'AUTO WIDE ANGLE' nameplate, while later versions used a shorter 90-degree throw and 'MC WIDE ANGLE' nameplates. The lens earned a following among vintage shooters for its combination of a genuinely fast f/2 aperture in a wide-angle, strong build quality, and excellent handling, all at an affordable price point. No swirl, glow, or invented nickname is supported by the reviews.

Verdict: The Vivitar (Kiron 22xxxxx) 28mm f/2 is a well-regarded, affordable fast wide-angle that reviewers praise for sharpness, bokeh, handling, and value, earning a 93% recommendation rate. It suits vintage-lens enthusiasts who want a bright 28mm with solid build and good rendering, provided they check for the common oily-iris problem before buying.
