In the era of mirrorless cameras the balance between performance and size is even more crucial. There is a growing demand for “compact high-performance high-quality lenses” and SIGMA responds to this call with the “I” series of full-frame mirrorless exclusive lenses. Available for L-Mount and Sony E mount DG indicates full-frame sensor coverage and DN indicates mirrorless-exclusive design. The I Series represent a new option: Premium Compact Primes that are stylish in appearance with impressive specifications and optical performance. Introducing the 90mm F2.8 DG DN | Contemporary lens. With its versatile mid-telephoto focal length the lens is the longest I series lens yet but still remains remarkably compact and light so is ideal for day-to-day use. The lens also utilizes the camera’s optical correction functionality which is an advantage of mirrorless systems SIGMA’s optical designers were therefore able to concentrate on correcting aberrations that can only be corrected by the optical design thereby improving rendering performance and reducing the size and weight of the lens. With a minimum focusing distance of 50cm and a maximum magnification ratio of 1:5 close-up macro-style photography is possible. The lens highlights the subject allowing photographers to focus in on fine details or create more abstract compositions. The 90mm F2.8 DG DN | Contemporary shares the same 64mm maximum diameter and 55mm filter size as the 24mm F3.5 DG DN | Contemporary and the 45mm F2.8 DG DN | Contemporary making them a natural trio especially for filmmakers who use filters more regularly. – All I Series lenses feature an all-metal body with high-precision metal internal parts and a metal hood – All I Series lenses feature a manual aperture ring and knurled surfaces for an enjoyable tactile experience – An optional magnetic cap holder CH-11 features a mini-carabiner for clipping to a camera bag jacket or belt loop and has a donut-style center hole to easily pop off a cap when it is time to place back on the lens
