Sigma 135mm f/1.4 DG Art Lens - Leica L

Highlight your subject against extremely large, natural bokeh to create stunning portraits, product images, and lifestyle shots with the 135mm f/1.4 DG Art Lens from Sigma. 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. For firmware updates, this lens is compatible with the separately available UD-11 USB Dock.

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.
