At home under the Art category, this high-performance standard lens is designed exclusively for mirrorless interchangeable lens cameras and has the equivalent angle of view as 120mm on the Micro Four Thirds system and 90mm on the E-mount system (35mm equivalent focal length. This lens features SLD (Special Low Dispersion) glass, which helps minimize axial and transverse chromatic aberration. Glass mold aspherical lenses help minimize coma.  Optimized power distribution helps ensure exceptional image quality from the center to the edges of the images. In addition, the inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focusing position. The superior telecentric optical design improves the image quality throughout the frame. The optical design also allows the lens to be compact and lightweight. This lens benefits from a newly developed linear AF motor, which moves the lens elements directly without the need for gears or the drive of other mechanical parts. This system ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photos. The lens features a rounded 7-blade diaphragm creating an attractive blur to the out of focus areas of the image. This Sigma 60mm F2.8 DN has a minimum focusing distance of 50cm/19.7in and a maximum magnification ratio of 1:7.2, and comes in either a silver or black finish.
