Sigma 28-105mm F2.8 DG DN Art (Sony E)
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.
