New Standards Of Optical Performance For The Contemporary Line.
The SIGMA 65mm F2 DG DN | Contemporary for Sony E 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. In addition to the beautiful bokeh effect thanks to the control of spherical aberration, the reduced vignetting effects help curb lemon-shaped or swirly bokeh and give photographers greater control over the out of focus areas of their images. On top of it all, the SIGMA-standard anti-ghosting and anti-flare technology ensures high-end performance in backlit conditions.
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.
