The FX30's advanced imaging system is on par with other options in Sony's Cinema Line—capturing detailed 10-bit UHD 4K imagery at up to 120 fps—giving it specs fitting a true cinema camera. The newly-developed 26MP APS-C Exmor R CMOS sensor and BIONZ XR processor are able to create high-quality 4K images with the Super 35mm (16:9) area. This system is capable of capturing 14+ stops of dynamic range and benefits from Dual Base ISO architecture to improve low-light performance.
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. The optical design incorporates a series of low dispersion and aspherical elements that greatly reduce a variety of aberrations in order to achieve high sharpness, enhanced clarity, and improved color accuracy. Both Super Multi-Layer and Nano Porous Coatings have also been applied to improve contrast and color rendering by suppressing lens flare and ghosting when working in strong lighting conditions.
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.
