Overview:
Sigma 24-70mm f/2.8 Sony DG DN Art Lens for Sony E, Positioned as a workhorse lens among Sony E-mount full-frame mirrorless systems, the Sigma 24-70mm f/2.8 DG DN Art is a versatile wide-angle to portrait-length zoom characterized by its f/2.8 constant maximum aperture. The bright design suits working in available lighting conditions and also affords increased control over depth of field.
Complementing the optical attributes, this lens also sports a stepping AF motor, which yields fast, precise, and notably quiet autofocus performance. At the wide end of the zoom range, a maximum magnification ratio of 1:2.9 suits working with close-up subjects and an 11-blade diaphragm contributes to a pleasing bokeh quality. Additionally, a weather-sealed design benefits working in trying environmental conditions.
- As part of the Art line within Sigma’s Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
- Standard zoom is designed for full-frame Sony E-mount mirrorless cameras, however can also be used with APS-C-format models where it will provide a 36-105mm equivalent focal length range.
- Constant f/2.8 maximum aperture is well-suited for working in available light conditions and also provides greater control over depth of field when using shallow depth of field techniques.
- Six F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.
- Three aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.
- Both Super Multi-Layer and Nano Porous Coatings have been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
- Integrated stepping motor realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance.
- At the wide-angle end of the zoom range, a minimum focusing distance of 7.1″ is possible with a maximum magnification of 1:2.9 to suit working with close-up subjects. At the telephoto end, the minimum focusing distance is 1.25′ with a maximum magnification of 1:4.5.
- Integrated AF-L button can be programmed to adjust various shooting settings and the lens also features a dedicated AF/MF switch and a zoom lock switch to prevent the barrel from accidentally extended.
- Rounded 11-blade diaphragm contributes to a pleasing bokeh quality.
- Brass bayonet affords improved mounting accuracy and rigidity and rubber sealing is incorporated in the mount’s design to render it dust- and splash-resistant.
