Featuring a back-illuminated design, this full-frame 61MP Exmor R CMOS sensor offers a mixture of incredible resolution with high clarity, low noise, and a wide 15-stop dynamic range. The sensor's structure promotes impressive image quality and a copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution 61MP stills with a native sensitivity range from ISO 100-32000, which can be further expanded to ISO 50-102400.
Featuring improved rendering performance in a shorter and lighter body, Sigma's flagship Sony E-mount 24-70mm f/2.8 DG DN II Art Lens deploys an advanced optical design for gains in sharpness, resolution, and portability. Additions like accelerated autofocus, a clickable aperture ring, and a scant, 6.7" minimum focusing distance make this small-footprint follow-up ideal for those seeking versatility without compromising excellence.
Sophisticated Optical Design
Six "F" Low Dispersion (FLD), two Special Low Dispersion (SLD) elements, and five aspherical elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy. Also, increased control over sagittal coma flare yields high resolution across the entire frame.
In addition to superior optical performance, the five aspherical elements contribute to the lens' compact build with their thin, highly polarized construction.
The bright, f/2.8 aperture and rounded 11-blade diaphragm produce a large, beautiful bokeh effect.
