Sigma 28-105mm f/2.8 DG DN Art Lens (L-Mount)

The Sigma 28-105mm f/2.8 DG DN Art Lens (L-Mount) is designed for L-Mount-mount full-frame mirrorless camera systems and features a 28-105mm zoom range complete with a fast constant f/2.8 maximum aperture. From sweeping landscapes to flattering portraits, this zoom lens will suit it all, and its wide zoom range can work as one lens to shoot it all. Giving you proximity to your subjects, the lens offers a minimum focusing distance of 15.8" that stays consistent throughout the zoom range. It has an HLA motor so you can capture high-resolution imagery with quick, quiet, and precise autofocusing, and a rounded 12-blade diaphragm helps deliver pleasing and circular bokeh. It repels damaging debris and particles from the lens thanks to a combined water- and oil-repelling front lens element coating distributed alongside dust- and splash-resistant design with the Sigma 28-105mm f/2.8 DG DN Art Lens (L-Mount).

Lens Features

Two AF-L buttons are available to be programmed based on your shooting needs.

A zoom lock switch prevents the lens from accidentally extending.

The lockable aperture ring with click/de-click function enables smooth adjustments and prevents unintentional value changes.

Optical Design

Two F Low Dispersion (FLD) and one Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy

Five aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.

A water- and oil-repellant coating is applied to the front lens element to minimize any liquids from sticking to the glass.

Additional Lens Benefits

• Lens construction: 18 elements in 13 groups.
• Lens weight is approximately 2 lb. The lens barrel near the mount is made of magnesium instead of aluminum, contributing to its lightweight design and allowing users to shoot longer without fatigue.
• 82mm filter thread for wide compatibility.
