Description and Reviews

Key Take-Aways:

The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary is a compact 1135g ultra-telephoto zoom with optical stabilization, designed as Sigma’s first long zoom for full-frame mirrorless. Professional reviews praise its sharpness, effective stabilization, portability, and value, while noting trade-offs such as the relatively slow maximum aperture, some vignetting and chromatic aberration, and slower autofocus tracking compared to higher-end telephoto zooms. As of Sep 14 2025, user sentiment is positive, with many considering it a practical and affordable way to reach 400mm, though some wildlife and sports photographers find its autofocus and aperture limiting for fast action or low light.
