The Sigma I Series introduces compact, beautifully designed, high-performance optics for mirrorless camera systems. In its first collection, Sigma introduces a high-spec, daily use lens to the Contemporary lens line-up, which combines excellent resolving power with a small body that is perfectly weighted for mirrorless systems. The Sigma I Series 65mm f/2 Contemporary DG DN is a compact, short telephoto prime lens that offers a stunning photographic experience for mirrorless users. Long supported among photography lovers and even used for shooting films, a 65mm lens allows a slightly more compressed perspective than standard lenses, opening up a variety of creative approaches for both photography and film-making. The ultra-sharp 65mm f/2 DG DN Lens can capture extremely fine detail even wide open at its maximum aperture of F2, and produces large and round bokeh.

New Photographic Experience for Mirrorless Users

The Sigma I Series features full-frame-compatible lenses that offer mirrorless users a new and better alternative, both in the experience of shooting with the lens and in the impressive results it is able to achieve. One of the key advantages of mirrorless cameras is their smaller form-factor, and this new 65mm optic is designed to be perfectly matched to these more compact systems without sacrificing performance. This combination of superb optical quality with exceptional portability, not previously possible with DSLR systems, will bring new opportunities to this and future generations of photographers. Simultaneously, Sigma is aware that, in this day and age when we have such huge diversity when it comes to what we use to photograph, as represented by smartphones, people look for something more than a mere act of taking pictures when they choose to own a camera and lenses.

Optical Performance

The 65mm f/2 DG DN | Contemporary brings to the table the highest level of optical performance at a maximum aperture of f/2 with a lens body of a size that matches a mirrorless system. Axial chromatic aberration, 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 chromatic 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 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.

Amazing Build Quality with 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, which 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 an exquisite feel to touch 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.
