Simultaneously, SIGMA is aware of the increasing number of camera options there now are, especially with the growth in smartphone ownership, so people are looking for something more than a mere act of taking pictures when they choose to own a camera and lenses. SIGMA's excellence in development and processing technologies has been built up since its founding in 1961, and has become further sophisticated with the introduction of the SIGMA Global Vision range in 2012. With this as a base, SIGMA has given careful thought to how photographers use and enjoy their lenses, including optical design, advanced functionality, superb build quality and the experience of picking up and using the lens, and with all of this carefully considered, the I series was born.
New standards of optical performance for the Contemporary line
The 65mm F2 DG | Contemporary brings to the table the highest level of optical performance even at its maximum aperture of F2. 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 resolve extreme detail. A pair of glass-moulded aspherical lenses is used to correct spherical and comatic aberration, as well as astigmatism, while also helping make the optical configuration smaller in size. A combination of the latest optical design and advanced processing technology gives the 65mm F2 DG | 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 effect of vignetting help curbs lemon-shaped or swirly bokeh and give photographers greater control over the out-of-focus areas of their images. And SIGMA-standard anti-ghosting and anti-flare technology ensures high-end performance in backlit conditions.
Exceptional build quality with a compact form-factor
All I series lenses have an all-metal construction. The precision-cut aluminium 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 the production of the cine lens line-up for professional film-makers and provide an exceptionally premium feel that make these lenses a joy to use.
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.
Features an aperture ring, metal lens hood and magnetic lens cap
Despite being exceptionally small and light for an all-metal, full-frame, wide-aperture lens, the 65mm F2 DG |C has impressive functionality, with an aperture ring that allows photographers to change apertures on the lens, or when set to Auto, in-camera if preferred. Special sound-deadening grease has been used to give the ring a precise but smooth action. Included in the box is the regular plastic SIGMA lens cap, as well as a metal cap that attaches to the front of the lens magnetically. A lens cap holder is available to buy separately, which can be clipped to a bag strap or clothing and holds the cap magnetically while the lens is being used. The lens comes with an all-metal lens hood.
