Overview

The Sigma 18-200mm F3.5-6.3 DC is a superzoom for APS-C DSLRs, offering a versatile 11x range (28.8-320mm equivalent) in a compact, lightweight body. Optical strengths include good color reproduction and sharpness, but weaknesses include distortion, vignetting, and fringing requiring correction. Build quality is decent with a stiff zoom ring and a nearly useless manual focus ring. Autofocus can hunt, especially at the long end. It suits travel and family photographers seeking an all-in-one solution on a budget.
