I series "Premium Compact Primes" for mirrorless usersThe Sigma I series features full-frame compatible lenses that offer new value to mirrorless systems. The combination of superb optical performance with a level of compactness that is perfectly suited to smaller and lighter modern mirrorless cameras will bring you new opportunities for a perfect shot. Sigma is aware that in today's world we have a wide range of camera choices, especially with the increase in mobile phone ownership.But with many people look for something more than a mere act of "taking pictures" when they choose to own a camera and lenses, I series lenses offer the ultimate combination of superb optical performance, outstanding usability and compact form-factor. Sigma's excellence in development and production technologies has been built up since our founding in 1961 and became increasingly sophisticated with the introduction of the Sigma Global Vision brand in 2012. With this as a base, Sigma has given careful thought to the quality of the products, the feeling of using it and the pleasure of owning it. This is how the I series was born.New standards of optical performance for the Contemporary lineThe 35mm F2 DG | 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 aberration, a point of particular concern with a bright lens, is corrected with SLD glass, while an optimal 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 cutting edge optical design and advanced processing technology, the 35mm F2 DG | Contemporary offers consistent, high resolving power right across the frame.Use of multiple high-precision aspherical glass molded lensesThe 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-factorAll 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 lineup 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.
