    Overview

    The Promaster AF 70-300mm f/4-5.6 LD Tele-Macro is a budget telephoto zoom with mixed optical performance. Sharpness is good in the center at 70mm but softens at longer focal lengths and edges, with notable chromatic aberration. Build quality is plasticky but acceptable for its price, with a smooth zoom ring and decent macro capability at 1:2 magnification. It suits beginners or those needing an affordable telephoto for outdoor use, but serious photographers may find its limitations frustrating.
