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.
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.
