Sigma 135mm f/1.4 DG Art Lens (Sony E)

Sigma 135mm f/1.4 DG Art Lens
Ultra-Fast Telephoto Prime – f/1.4 Aperture, Dual HLA AF Motors, 13-Blade Diaphragm & Removable Arca-Type Tripod Socket

The Sigma 135mm f/1.4 DG Art is an ultra-fast telephoto prime lens engineered for high-resolution portrait, product, and lifestyle photography alongside professional cinema production. Designed to deliver extreme subject isolation paired with smooth, expansive bokeh, this Art-series lens utilizes an optical architecture featuring four F Low Dispersion (FLD) elements and two aspherical elements to suppress chromatic aberrations and maintain crisp edge-to-edge detail wide open at f/1.4.

Driven by Sigma’s dual High-Response Linear Actuator (HLA) focusing system, the lens provides rapid, quiet, and reliable autofocus tracking throughout its focus range. Optical elements are specifically engineered to suppress focus breathing, making it a powerful tool for handheld or rigged video capture. Built for demanding outdoor shoots, the weather-sealed barrel features a water- and oil-repellent front element coating, an assignable AFL button, a click/de-click aperture ring with a lock switch, and a removable Arca-type compatible tripod foot.
