The Art line is comprised entirely of high-end Sigma lenses with an artistic bias. One of these is a zoom with the most popular set of focal lengths of 24-70 mm, flavored with a constant maximum aperture of f / 2.8.
High-end build
The model is assembled in a dust- and moisture-proof case with a metal "back" for screwing to the "carcass" of the camera. The bayonet mount of the lens is surrounded by a rubberized insert, which is an additional link to protect the "insides" of the lens from external influences. The body of the Sigma 24-70mm f/2.8 DG OS HSM Art has a wide zoom ring, a narrow manual focus ring (requires getting used to), focus and stabilization mode slide switches, and a window with a marked distance scale.
Equipment
The lens "draws" a sharp and juicy picture with high micro-contrast starting from an open aperture of f / 2.8. In quick focus, he is assisted by the built-in HSM (Hyper-Sonic Motor) ultrasonic drive. The model also carries an optical image stabilizer on board, which helps out when the ambient light is not good enough and helps to get a smooth picture when shooting a video sequence.
Optical structure
The optical design of the Sigma 24-70mm f/2.8 DG OS HSM Art contains 19 elements, which are combined under the wing of 14 groups. Among them are three low dispersion SLD lenses and four aspherical elements to reduce aberrations. On the front lens of the lens, you can "put on" a filter with a diameter of 82 mm. Finally, in the story about the model, one cannot ignore the 9-blade diaphragm, with which you can “draw” spectacular bokeh with regular-shaped “rounds” in the blur zone. The last important arguments in favor of the model are a more humane price tag than for “native” glasses from A-brands with similar FRs, and compatibility with the entire mirror “guard” of full-frame cameras.
