Vivitar Series 28-70mm F/3.8-4.8 Zoom Lens - Minolta MD Mount - minor fungus

Vintage manual-focus zoom lens from Vivitar’s Series 1-inspired lineup, compatible with Minolta MD mount film cameras. This compact mid-range zoom covers wide to short telephoto and includes a macro mode for close-up work. Manufactured by Kobori in the mid-1980s, known for solid build and decent optical performance.

This copy shows minor internal fungus, visible under bright light. It may slightly reduce contrast in high-flare conditions but remains usable for general shooting. Focus and zoom rings are smooth, and aperture blades are clean and snappy.

Collector Notes:

This lens is part of Vivitar’s later manual-focus lineup, often overshadowed by Series 1 optics but still well-regarded for its compact build and macro versatility. The fungus is typical of age and storage but does not severely impact usability. A good fit for collectors, tinkerers, or those seeking a low-cost zoom for Minolta MD bodies.
