Product Specifications

Basic Information

Product Features

BOKEH-MASTER, the longest focal length in the Art F1.4 series for full-frame lenses, with a focus on resolving power and bokeh effect

- Optical performance that challenges the limits of F1.4
Aiming for the highest performance among large-aperture medium telephoto lenses with a maximum aperture of F1.4, the lens is composed of 17 elements in 12 groups, an unprecedented number for a single focal length lens, including three FLD glass elements, two SLD glass elements and one aspherical lens element. The lens construction includes three FLD glass elements, two SLD glass elements, and one aspherical lens element. The overwhelming sharpness of the in-focus area and the out-of-focus area's blur with little coloration are also powerful in portrait and other photography. Sagittal coma flare is also well corrected, making it ideal for star photography.

- Abundant peripheral light intensity
The most effective way to obtain abundant peripheral illumination is to increase the diameter of the lens front element, and the SIGMA 105mm F1.4 DG HSM Art has a larger filter diameter of 105mm, which allows it to provide an overwhelmingly large amount of peripheral illumination compared to similar products in its class. This allows the lens to suppress aperture erosion, making it ideal for portraits and other out-of-focus expressions.

- Dustproof and drip-proof construction for professional use
As with the Sports line, the lens is dustproof and drip-proof, with sealed joints at the mount, manual ring, and exterior, allowing shooting in a variety of conditions regardless of weather conditions. In addition, the frontmost surface of the lens is coated with a water and stain repellent coating. The lens surface can be easily maintained. In addition, the fast and accurate autofocus system enables instantaneous shooting.

- Specifications to Support Photography
The dedicated hood is made of CFRP (Carbon Fiber Reinforced Plastic), a polycarbonate material containing carbon fiber used for the interior and exterior of aircraft, instead of the commonly used ABS resin. CFRP is used for the interior and exterior of airplanes, etc. It is both light and strong. The removable tripod stand can be directly attached to an Arca-Swiss type head or clamp. A dedicated protective cover is included to prevent interference when taking pictures with the tripod stand removed. It also helps to reduce the weight burden when carrying the camera.

- AF optimized for L-mount*.
The AF drive control program tuned for each lens and high-speed communication enable shooting with comfortable speed and high precision AF. AF-C mode is also supported. *Correspondence to each function is limited to what the camera supports.
