New Standards Of Optical Performance
For The Contemporary Line
The SIGMA 35mm F2 DG DN | Contemporary lens for Sony E-mount brings to the table the highest level of optical performance at a maximum aperture of F2 with a lens body of a size that matches a mirrorless system. The lens design also provides a very good correction of sagittal coma aberration, making it capable of capturing details fine enough for it to be used for night sky photography. Thanks to cutting edge optical design and advanced processing technology, the SIGMA 35mm F2 DG DN | Contemporary lens for Sony E-mount offers consistent, high resolving power right across the frame.
Use Of Multiple High-Precision Aspherical Glass Molded Lenses
The surface of molds for glass molding, which is a process that forms optical components by pressing glass materials at high temperatures, requires ultra-high precision. SIGMA uses high-precision molds whose surfaces are controlled with an accuracy of ±5 nanometers (0.000005 mm) or smaller. High precision aspherical glass molded lenses archives both good aberration correction and compact lens size.
