SIGMA 24-70MM F2.8 DG DN ART SONY E

Sigma 24-70mm f / 2.8 DG DN Art Lens for Sony E

Positioned as a workhorse lens among Sony's E-mount full-frame mirrorless systems, the Sigma 24-70mm f / 2.8 DG DN Art is a versatile wide-angle to vertical-length zoom characterized by its constant maximum aperture f / 2.8. The bright design adapts to work in available lighting conditions and also allows greater control over depth of field. The optical design incorporates a series of low dispersion and aspherical elements that greatly reduce a variety of aberrations for high sharpness, improved clarity and improved color accuracy. Super Multi-Layer and Nano Porous coatings have also been applied to improve contrast and color reproduction by suppressing lens flare and ghosting when working in bright lighting conditions.
Complementing the optical attributes, this lens also has a progressive AF motor, which produces fast, accurate and remarkably quiet autofocus performance. At the wide end of the zoom range, a maximum magnification ratio of 1: 2.9 accommodates working with close-up subjects, and an 11-blade diaphragm contributes to pleasing bokeh quality. In addition, a weather-sealed design benefits working in difficult environmental conditions.
As part of the Art line within Sigma's Global Vision series, this lens is designed for truly remarkable optical performance and is ideal for creative and artistic applications.
The standard zoom is designed for Sony full-frame E-mount mirrorless cameras, however it can also be used with APS-C format models where it will provide an equivalent focal length range of 36-105mm.
The constant maximum aperture of f / 2.8 is suitable for working in available light conditions and also provides greater control over depth of field when using shallow depth of field techniques.
Six low-dispersion F (FLD) elements and two special low-dispersion (SLD) elements dramatically reduce chromatic aberrations and color stripes throughout the zoom range to improve clarity and color accuracy.
Three aspherical elements control spherical aberrations and distortion for sharpness and accurate representation.
Super Multi-Layer and Nano Porous coatings have been applied to the lens elements to minimize lens flare and ghosting and help produce images with high contrast and neutral colors, even in backlit conditions.
The integrated stepping motor performs fast, 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 focus distance of 7.1 "with a maximum magnification of 1: 2.9 is possible for working with close-up subjects. At the telephoto end, the minimum focus distance is 1.25 ' at a maximum magnification of 1: 4.5.
The 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 extending.
The rounded 11-blade diaphragm contributes to a nice quality of bokeh.
The brass bayonet offers improved mounting rigidity and precision, and the rubber seal is built into the bracket design to make it dust and splash resistant.
