Defined by its extremely large, natural bokeh, the 135mm f/1.4 DG Art Lens from Sigma highlights the subject against gorgeous bokeh to create stunning portraits, product images, and lifestyle shots. This telephoto lens is designed for high-resolution rendering and utilizes FLD and aspherical glass to suppress chromatic aberration, delivering crisp detail even when wide open at f/1.4.
Versatile Lens Construction
- The lens features an assignable AFL button for custom functions as well as a focus mode switch and aperture ring lock. The aperture ring can be changed from clicked to declicked for smooth video operation.
- A water- and oil-repellent coating on the front lens element makes it possible to shoot in harsh outdoor environments, while the dust- and splash-resistant construction keeps the internal elements protected.
- Included is a removable tripod socket compatible with Arca-type clamps for increased stability due to the weight of the lens. The tripod socket can be replaced with the supplied protective cover.
Complex Optical Design
- Sigma combines two aspherical elements and four F Low Dispersion (FLD) elements to ensure clarity from wide open at f/1.4 through the rest of the aperture range.
- A total of 17 elements in 13 groups, as well as a 13-blade rounded diaphragm, create beautiful circular bokeh, minimizing vignetting and color bleeding even at the edges.
- Sigma's Super Multi-Layer Coating is used to optimize backlight resistance, minimizing potential lens flare and ghosting.
Powerful Focusing System
- No longer purely for photography, the lens elements have been optimized to reduce focus breathing, making it a strong choice for professional video use.
- Powered by Sigma's dual HLA (High-response Linear Actuator) focusing system for fast and quiet autofocusing throughout the entire telephoto focusing range, allowing fast-moving subjects to be captured reliably.
Compatible with separately purchased USB Dock UD-11 for firmware updates.
