Vivitar — 80-200mm f/4.5-5.6 manual telephoto zoom with macro switch, multi-mount
Vivitar built its catalog by having Japanese manufacturers produce lenses to its own specification, then selling them through camera shops rather than as part of a matched system. The 80-200mm f/4.5-5.6 was one of several similarly specified telephoto zooms in Vivitar's mainstream line during the 1980s.
It is a manual-focus zoom with a variable maximum aperture of f/4.5 at 80mm narrowing to f/5.6 at 200mm, typically fitted with a macro-focus override near the 200mm position. It was offered across the major manual-focus SLR fittings sold in camera stores of the period. Specific weight, filter thread and optical formula are not confirmed from available sources.
Rendering is typical of budget variable-aperture zooms of its generation: usable centre sharpness by mid-apertures with softer corners and reduced contrast wide open, and moderate flare without modern coatings in strong backlight.
Examples turn up cheaply secondhand and are usually bought as an inexpensive step into telephoto work rather than for critical use. Buyers should check the zoom and focus rings for smooth travel without excess play, confirm the aperture blades close evenly, and inspect the glass for haze or separation.
