Sigma Art 105mm 1.4 DG HSM für Sony E

The Sigma 105mm f/1.4 DG HSM ART is quite a beast. Optically, it's great - very sharp fully open and truly superb at medium aperture settings. Lateral CAs are low and distortions are absent. Some vignetting is obvious at f/1.4, but much reduced at f/2 already. The bokeh is silky smooth in the image background. Less obvious "cat eyes" would have been nice given that the front element is so huge. Axial CA can show up in difficult scenes. The build quality is superb. However, the size and weight will make you suffer - which is typical for many Sigma lenses of this era. Despite the big glass elements, the AF is quick on the D850. In Nikon mount, the Sigma 105mm f/1.4 DG HSM ART faces stiff competition from the Nikkor AF-S 105mm f/1.4 E. The Nikkor is marginally better optically, but much more compact and lightweight. However, you should be able to find a good deal on the used market and the Sigma is also available in mirrorless mounts (Sony E, L-mount).

The Sigma 105mm F1.4 DG HSM is a new short telephoto prime lens for full-frame DSLR cameras that's designed to deliver the ultimate in bokeh. The Sigma 105mm F1.4 DG HSM is comprised of 17 elements in 12 groups including three FLD glass elements, two SLD glass elements, and one aspherical lens element, and features a rounded 9 blade diaphragm which creates an attractive blur to the out of focus areas of the image. It has a Hyper Sonic Motor (HSM) for smooth, quiet and accurate autofocusing, a Super Multi-Layer Coating to reduce flare and ghosting, a minimum focusing distance of 100cm / 39.4in and a maximum reproduction ratio of 1:8.3, and a removable, rotating Arca-Swiss tripod foot.

With the 105mm f1.4 ART, Sigma has produced one of their finest lenses in their acclaimed Art line: it's extra sharp and has the most beautiful Bokeh I've ever seen. Plus it's the only f1.4 105mm lens you can get for your Canon DSLR or Sony mirrorless camera. It might be on the large and very heavy side and has no optical stabilization but its optical performance makes the new Sigma replace the Nikon 105mm f1.4E as the reference large aperture 105mm lens. Thus the Sigma 105mm f1.4 Art easily earns a Highly Recommended.
