Sigma 135mm f/1.8 DG HSM Art Review

The Sigma 135mm f/1.8 DG HSM Art is a fast telephoto prime positioned as a professional-grade lens for portraiture, events, and selective subject isolation. At f/1.8, it offers one of the widest apertures in the 135mm class, delivering strong background separation and low-light performance. Part of Sigma's acclaimed Art series, it targets photographers who prioritize optical quality and build over compactness. The $1,539 MSRP places it in the premium tier, competing with first-party options from Canon, Nikon, and Sony while undercutting some of those alternatives. It's compatible with multiple mounts, making it a versatile choice for shooters who may switch systems or use adapters. The lens appeals to portraitists and event photographers who need a longer working distance paired with fast glass.
