The 65mm F2 DG DN | Contemporary 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.

Axial chromatic abberation, which tends to be noticeable with medium and telephoto lenses and cannot be effectively reduced in-camera, is corrected thoroughly with the use of SLD glass, allowing it to capture sharp details. A pair of glass-molded aspherical lenses is used to correct spherical and comatic aberration, as well as astigmatism, while also helping make the lens configuration smaller in size. A combination of the latest optical design with advanced processing technology that brings life to the former gives the 65mm F2 DG DN | Contemporary its excellent optical performance as well as compact size.

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.

Exceptional I series build quality with a compact form-factor

All I series lenses have an all-metal construction. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish, but provide superb durability, ehick improves the quality of the entire product. Metal materials are also used in internal structures that slide with the operation ring for added robustness. These high-precision components crafted with SIGMA’s cutting-edge metalworking technology are also used in SIGMA’s Cine Lens line-up for professional cinematographers and provides and exquisite feel to tocuh as well as sound effects, making photographers want to reach for it and play with it over and over again.

The cover ring between the focus ring and the aperture ring has hairline processing that is also used for the rear cylinder of the Art line. This covering functions as a finger hold when attaching or detaching the lens.
