Sigma 135mm f/1.4 DG Art Lens
Highlight your subject against a backdrop of beautifully large, natural bokeh with the Sigma 135mm f/1.4 DG Art Lens, designed to capture striking portraits, lifestyle shots, and product photography with exceptional depth and realism. This telephoto prime lens combines a bright f/1.4 aperture with advanced optical precision to deliver superb image quality even when shooting wide open. FLD and aspherical elements work together to minimize chromatic aberration, ensuring crisp, high-resolution detail and smooth tonal transitions in every frame.
Precision Engineering and Versatile Handling
Built for both photographers and cinematographers, the 135mm f/1.4 DG Art features an assignable AFL button for custom functions, along with a focus mode switch and aperture ring lock for intuitive control. The click/de-click option on the aperture ring offers seamless switching between tactile still shooting and smooth, silent adjustments during video recording.
For demanding environments, the lens employs a water- and oil-repellent coating on the front element and a dust- and splash-resistant structure to protect against the elements. A removable Arca-type compatible tripod socket provides added stability when working on a rig or tripod setup and can be swapped with a protective cover for handheld shooting.
Exceptional Optical Design
Sigma’s advanced optical formula features 17 elements in 13 groups, including two aspherical and four FLD elements that effectively suppress distortion, color fringing, and edge softness. The 13-blade rounded diaphragm produces smooth, circular bokeh that enhances background separation without harsh edges, even at the maximum aperture. To further optimize contrast and clarity, Sigma’s Super Multi-Layer Coating reduces flare and ghosting when working in strong backlight conditions—perfect for both indoor studio portraits and outdoor golden-hour scenes.
Fast, Quiet, and Reliable Autofocus
Engineered with Sigma’s dual HLA (High-Response Linear Actuator) system, the 135mm f/1.4 delivers rapid, precise, and virtually silent autofocus performance. The focusing elements are optimized to minimize focus breathing, making this lens equally suited for high-resolution still photography and professional video work. Whether tracking fast-moving subjects or focusing critically at shallow depths of field, the lens ensures smooth and confident operation throughout the telephoto range.
