Minolta's budget AF telephoto zoom — the early 75-300mm for A-mount film and digital cameras.
The Minolta AF 75-300mm f/4.5-5.6 is an early autofocus telephoto zoom for Minolta's A-mount system, released around 1988. It provided affordable telephoto reach for Minolta's pioneering AF SLR system. As a consumer-grade lens, it prioritised affordability and convenience over optical excellence, targeting casual photographers wanting basic telephoto capability.
Optical performance is basic. Centre sharpness is acceptable at shorter focal lengths but weakens towards 300mm. The slow variable aperture limits low-light use. Adequate for daylight telephoto work. As an early AF design, the autofocus motor is functional but slow and noisy by modern standards. Multiple versions exist with incremental improvements over the production run.
Minolta A mount (compatible with Sony A-mount bodies). Filter thread is 55mm. Weight is approximately 445 grams — moderate. Build quality is basic plastic. The A-mount compatibility means it works on all Sony A-mount DSLRs and SLTs. Adapts to Sony E-mount via LA-EA adapters. No image stabilisation — benefits from Sony body-based SteadyShot.
Very cheap on the used market given declining A-mount demand. Check AF motor operation and smooth zoom. Not recommended for demanding work. Only of interest to A-mount system owners wanting cheap telephoto reach. The Sony 75-300mm or Tamron 70-300mm alternatives are marginally better at similar prices.
