    Overview

    The Sigma AF 100-300mm f/4.5-6.7 DL is a compact, lightweight telephoto zoom with good center sharpness at f/8-f/11, especially in the 100-200mm range. Weaknesses include softness wide open and at 270-300mm, with blooming and need for post-processing (BestLightPhotoBlog). Build is solid with a stainless steel mount, but the front element rotates and zoom extends (BestLightPhotoBlog). It suits budget-conscious photographers seeking an affordable telephoto for good light, but not for low-light or demanding sharpness (BestLightPhotoBlog).
