    Overview

    The Sigma AF 28-135 mm f/3.8-5.6 Aspherical IF Macro is an affordable all-in-one zoom with macro capability (1:2 at 135mm). Optical performance is mixed: it delivers good sharpness and color balance in the center, but suffers from softness, light fall-off, distortion at extremes, and severe flare on digital. Build is adequate for the price, though autofocus is slow in low light. It suits budget-conscious photographers who need a versatile range and macro, but may disappoint on high-resolution digital bodies.
