Mar 16, 2021 ·  The new Sigma 85mm F1.4 DG DN Art lens is built purely for mirrorless cameras and represents a complete redesign, with an all-new optical path and autofocus system. It’s much smaller and lighter, at 83x94mm and 630g, yet packs a lot in with a raft of high-end handling features that are absent in the older DG HSM lens. 

Optics: The Sigma 85mm f1.4 DG DN Art is a pretty complex design with 15 elements in 11 groups including 5 special dispersion elements and 1 aspherical element. This is similar to the Sigma HSM. The Sony is less complex with 11 elements (including 3 special dispersion elements and one aspherical element) in 8 groups. [+] 

Feb 08, 2017 ·  The Sigma 85mm F1.4 Art hasn't been on the market long, but it has already begun to make some serious waves. Lenstip and DxO have rated it the sharpest 85mm lens ever created, beating out even the legendary 85mm F1.4 Zeiss Otus, which isn't something that we take lightly. 

Nov 17, 2020 ·  Compared to the Sigma 85mm f1.4 DG HSM Art, which is one of the largest and heaviest 85mm lenses we’ve tested, Sigma’s latest example is far more compact and discards a vast amount of weight. To be precise, the E-mount version that we were sent for review works out 30mm shorter in length and 500g lighter than Sigma’s previous version. 

Sep 29, 2020 ·  The Sigma 85mm f/1.4 DG DN Art is a new lens from Sigma that's designed to be used with full-frame mirrorless cameras so John Riley's paired it with the Sony A7R III to find out how it performs. 

Sep 14, 2020 ·  The Sigma 85mm F1.4 DG DN Art is a very fast telephoto prime lens that has been designed from the ground-up for full-frame Sony mirrorless cameras. It's much smaller and significantly lighter than the two-year old 85mm F1.4 DG HSM lens that it effectively replaces. Priced at £999 / $1199, read our Sigma 85mm F1.4 DG DN Art review to find out if this is the best 85mm prime lens for Sony ... 

Aug 06, 2020 ·  5/5. About. Sigma's new 85mm F/1.4 DG DN Art is all new lens made for e-mount and l-mount full frame cameras. Rather than adapting the architecture of their existing 85mm DG HSN Art lens, Sigma has started at ground zero, creating a completely new and Promethean offering made expressly for mirrorless systems. 

The Sigma 85mm f/1.4 Art is an excellent portrait lens. The bokeh is buttery smooth and the contrast and sharpness make for a beautiful look to the image straight out of the camera. Repeatability of focus was a bit of an issue at times, and I occasionally had to refocus the lens when taking multiple shots at the same distance.

Sigma 50mm F1.4 DG HSM | A Lens review

The Good: The Sigma 50mm f1.4 lens is a well-designed lens that performs very well for its price. The Bad: It would be nice if it had image stabilization. The Bottom Line: While it's not cheap, the Sigma 50mm f1.4 lens provides great value for the money.  	My reaction to every fast lens Sigma release seems to be "I can't believe something this good costs less than $1,000." A new favorite -- the 50mm f1.4 DG HSM -- joins Sigma's Art series of lenses, which already includes two of my all-time sub-$1K favorites, the 35mm f1.4 and   . Designed to work on full-frame cameras (but, as always, compatible with APS-C models), the 50mm f1.4 has a premium-feeling build quality and excellent tension and tactile feedback on its focus ring, and it produces sharp, bright images with little distortion. There's some softness at its narrowest aperture, f16, and off-angle wide open it has a tendency toward chromatic aberration, but these are typical problems. (Caveats: I had only a day and a half to test the lens, and due to renovations in our office I could not run my usual  array of tests. If you're looking for test geekery before you buy, I suggest you check out Imaging Resources' results.) 	 	A note about the image samples: all are raw files with no luminance noise compression, which blurs the photo slightly, so that the most detail possible is preserved. As a result, your mileage may vary. 	  	The lens has the same design as the other fixed-focal-length lenses in the Art series: a simple, sturdy, all-metal construction with a comfortable rubberized focus ring and distance readout, plus a switch for manual/autofocus. Lots of folks have compared it to the Zeiss Otus 55mm f1.4 -- a fabulous lens to be sure, but far more expensive at close to $4,000, and it's almost twice the length not to mention somewhat heavier. I also like it better than the Canon 50mm f1.2L, which costs about $600 more (note, that's a subjective preference). I haven't tested Nikon's 50mm competitors, and as I was testing I couldn't help wishing I had a Nikon-mount version to see how it fared with an OLPF-free sensor in addition to my tests of the Canon-mount version with the   .

There's little distortion, I saw no vignetting, and it has nice clarity. There's some tendency to aberration at the widest apertures and softness at its narrowest, but marginal improvements in those areas make lenses more expensive. 	Yeah, I wish it had image stabilization and weather sealing; I wish all lenses for OIS-based systems had it. But as a great-performing portrait lens for less than $1,000 -- and with its characteristics, it would immediately improve a good APS-C dSLR as well -- it's seriously worth considering.
