Hanimex's variable-aperture OM telephoto — the 80-200mm f/4.5 for Olympus mount.
The Hanimex 80-200mm f/4.5 for Olympus OM is a budget telephoto zoom — slower than the constant f/4 version (ID 4521) with variable aperture. The 80-200mm covers standard telephoto. Hanimex quality at the most basic level. The OM mount adapts to mirrorless. The f/4 version is preferred if available.
Basic Hanimex quality. Slower than the f/4 version. Sharpness acceptable stopped down. Variable aperture limits consistency. The 80-200mm is standard telephoto. Build quality is basic. Not distinguished in any way. The constant f/4 version (ID 4521) is preferred at similar pricing.
Olympus OM mount. Weight and filter thread vary. Build quality is basic. Manual focus. Variable aperture. The OM mount is the practical advantage — adapts to mirrorless. The constant f/4 version is preferred. Better Zuiko alternatives exist.
Very cheap. Not recommended when the f/4 version or Zuiko alternatives exist. The variable aperture adds no advantage. Only if completely free. Better OM telephoto options at similar near-zero prices.
