Designed from the ground up for mirrorless cameras, the full-frame I series SIGMA 35mm F2 DG DN | Contemporary offers professional-level performance in a compact body.
The new I series range from SIGMA introduces compact, beautifully designed, high-performance optics for mirrorless camera systems. In its first collection, SIGMA introduces a versatile 35mm prime lens to the Contemporary line-up, which combines excellent resolving power with a small body that is perfectly weighted for mirrorless systems.
The classic 35mm wide-standard prime is a kitbag essential that most photographers would not want to compromise on, and this all-new I series model offers stunning optical performance with a wide F2 maximum aperture. Its modest size and weight make it portable enough to be carried around in a small kitbag for day-to-day shooting, but owing to its outstanding optical design and impressive build quality, it is equally well-suited to heavy professional use. The lens is ideal for street photography, astrophotography, environmental portraits, weddings and video. It is designed for photographers and film-makers who value the experience of taking a picture just as much as the quality of the final result.
I series｜’Premium Compact Primes’ bringing a new photographic experience to 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 35mm 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 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 35mm F2 DG DN | Contemporary brings to the table the highest level of optical performance even at its maximum aperture of F2. Axial chromatic aberration, a point of particular concern with a bright lens, is corrected with SLD glass. The placement of high-refractive index elements provides effective correction of various types of aberration, while keeping the amount of glass used to a minimum. The use of three high-precision glass-molded aspherical lenses, which were made possible thanks to advanced production technology at the Aizu factory, SIGMA’s only production site. These elements provide correction of spherical aberration and field curvature, and the fluctuation of aberration at the time of focusing. 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 SIGMA’s cutting-edge optical design and advanced processing technology, the 35mm F2 DG DN | Contemporary offers consistent, high resolving power right across the frame.
Exceptional 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, 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 35mm F2 DG DN |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.
