    Overview

    The Phoenix AF 100-400 mm f/4.5-6.7 is a budget telephoto zoom with mixed reviews. Optical performance is inconsistent: some users report sharpness and good color at both ends, while others describe it as 'soft as a down comforter'. Autofocus is very slow. Build quality is basic, with a plastic filter mount but a metal mount on some versions. It suits budget-conscious photographers who prioritize reach over speed and sharpness, but many strongly advise against it.
