The Sigma 135mm f/1.4 DG Art Lens for Sony E-mount is a premium telephoto prime renowned for its groundbreaking f/1.4 aperture at this focal length, delivering unmatched subject isolation and bokeh for portrait photographers. Released in 2025, it’s the fastest 135mm autofocus lens available for Sony full-frame cameras, filling a gap left by Sony’s own lineup. Key Specifications Aperture Range: f/1.4 to f/16 with 13 rounded blades for ultra-smooth bokeh. Optics: 4 FLD elements, 2 aspherical, minimizing chromatic aberration and delivering razor-sharp results even wide open. Build: Dimensions 4.4″ x 5.3″, 105mm front filter, weather-sealed, de-clickable aperture ring, removable tripod collar. Autofocus: Dual HLA motors for fast, precise tracking compatible with Sony’s subject detection. Minimum Focus: 43.4″ (1.1m) with 1:6.9 magnification. Performance Highlights Exceptional center sharpness at f/1.4 improves slightly by f/2.8 for flawless corners; bokeh rivals Sigma’s 105mm f/1.4 “Bokeh Master” due to a 96mm effective aperture diameter. It’s heavy (around 2.5 lbs based on similar Art lenses) but offers pro features like low vignette and flare resistance. Ideal Uses Best for portraits, low-light events, and subjects needing dreamy separation, though its size suits specialized rather than everyday carry. Reviews praise its value over pricier first-party options like Sony or Canon equivalents. Categories: Mirroless lenses, SIGMA
