Sigma 28-105mm f/2.8 DG DN Art - L-Mount
Precise Focusing, Exceptional Convenience
Flexing a vast zoom range and a fast constant aperture, the 28-105mm f/2.8 DG DN Art Lens from Sigma covers a variety of popular focal lengths, equipping you to capture everything from sweeping landscapes to intimate portraits all with one lens. Designed for Sony E-mount full-frame mirrorless camera systems, this lens provides a minimum focusing distance of 15.8" across the entire zoom, ensuring your ability to capture detailed close-ups of your subjects. Driven by an HLA motor, this lens delivers quiet and precise autofocusing, and its rounded 12-blade diaphragm ensures pleasing and circular bokeh. This lens repels damage from outside elements by coupling a water- and oil-repellent front lens element coating with a dust- and splash-resistant design.
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 colour fringing throughout the zoom range for improved clarity and colour accuracy.
- Five aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.
- A water- and oil-repellent 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.
