Vivitar 28-85 mm f/ 2.8-3.8 Auto Variable Focusing Lens
28–85mm · f/2.8–3.8
Overview
The Vivitar 28-85mm f/2.8-3.8 is a large, heavy metal zoom lens from the early 1980s with a one-touch mechanism that is awkward to use, as zoom and focus are coupled. It suffers from zoom creep, causing unintended zooming when tilted. Optical performance is not discussed in the excerpts, but the lens is noted for its wide and fast specifications. It may suit users interested in vintage manual-focus zooms despite handling quirks.
