Sigma 35mm8/25/2023 ![]() A minor detail, maybe, but still of some importance on a lens where attention to detail is the defining characteristic. The manual focusing ring is positioned a little too closely to the lens hood when it's fitted, though, so much so that my right thumb rubbed along the edge of the hood as I rotated the focusing ring. Polariser users should be pleased that the 58mm filter thread doesn't rotate on focus. ![]() There are no hard stops at either end of the range, making it a little more difficult to set focus at infinity. Manual focusing is possible by using the focus mode switch to toggle between AF and MF. The Sigma 35mm F2 DG DN lens has a rather narrow, ridged motor-assisted focus ring that is very nicely damped. The lens doesn't feature built-in optical image stabilisation, relying instead on the camera body's stabilisation system. The Sigma 35mm F2 DG DN lens has a metal lens mount and it accepts 58mm filters via metal threads on the front of the lens. It incorporates a brass bayonet mount that's supposedly more durable than a normal metal mount.Ī rubber seal is incorporated into the lens mount's design to make it dust- and splash-resistant. Sigma have really gone to town on the new I series, so much so that they've explained in great detail just how much thought has gone into it. It measures 70 x 67.4mm, making it very similar in size to the Sony FE 35mm F1.8, which measures 65.6 x 73mm.īuild quality is simply superb, far exceeding what you might expect from a mid-range, f/2 prime. Even with the supplied hood attached, it is still quite discrete for a 35mm lens. Its overall size is very well-suited to a camera like the Sony A7 III that we tested it with, as shown in the product photos. It is slightly cheaper than its main Sony rival, to the tune of around £100 / $100, which helps make up for the slightly slower maximum aperture. It's a little heavier than the comparable Sony FE 35mm F1.8, though, which at 281g is 44g lighter than this new Sigma alternative. Weighing in at 325g, the all-metal bodied Sigma 35mm F2 DG DN is light for such a premium full-frame lens. The Sigma 35mm F2 DG DN lens will be available in January 2021 priced at £549 / $639 in the UK and USA, respectively. There is a stepping motor for fast, quiet and precise auto-focusing, while the focusing ring provides fine manual focus control.Ī traditional aperture ring runs from f/2 to f/22 in third-stop increments with an Auto setting also available for camera-based aperture selection. It has a rounded 9-blade diaphragm which creates an attractive blur to out-of-focus areas of the image and an internal focusing mechanism which means the lens barrel doesn't move. This lens boasts a dust- and splash-proof structure and has a minimum focusing distance of 27cm with a maximum magnification of 0.18x. There's a Super Multi-Layer Coating to minimize internal reflections so that flare and ghosting do not occur. It features 10 elements in 9 groups, with one Special Low Dispersion (SLD) element to reduce chromatic aberrations and color fringing and three aspherical lenses which help to control distortion and spherical aberrations. The 35mm F2 DG DN was launched in December 2020 alongside the 24mm F3.5 DG DN and 65mm F2 DG DN lenses, with all three joining the existing 45mm F2.8 DG DN. This new lens is part of the Sigma I series of compact, high-performance, impeccably constructed primes for mirrorless camera systems, which boast a premium all-metal weather-sealed construction, a magnetic metal lens cap and a metal lens hood. It's also available for Leica / Panasonic / Sigma L-mount cameras. The Sigma 35mm F2 DG DN is a moderate wide-angle prime lens for Sony Alpha full-frame and APS-C E-mount mirrorless cameras, where it provides a 52.5mm equivalent focal length.
