A little over a year ago Sigma released their 50mm F1.4 DN ART lens, one that I was very happy to see from them. I gave it a very positive review here. But they weren’t done – just five or six weeks later they released the 50mm F2 DN lens, which I reviewed here. Flash forward to March of 2024, and we have a THIRD full frame Sigma 50mm release…all in less than a year. This is the premium option, however, in the form of the Sigma 50mm F1.2 DG DN| ART, coming to go head to head with Sony’s own 50mm F1.2 G Master lens. Sony’s 50mm F1.2 GM is amazing, but it also retails for $2000, leaving Sigma a lot of room to operate at the much lower price point of $1399 USD ($1899 CDN). But is the Sigma 50mm F1.2 DN worth considering over either the Sony 50mm F1.2 (or excellent F1.4 G Master) lenses, or even Sigma’s own 50mm F1.4 DN? Explore that idea with me in either my video review below or by reading my text review here.

Thanks to Sigma Canada (Gentec) for sending me a review loaner of this lens. As always, this is a completely independent review. *The tests and most of the photos that I share as a part of my review cycle have been done with the Sony a7RV along with the Sony Alpha 1 that serve as my benchmark cameras for Sony lenses.

One of Sigma’s first dedicated full frame DN (mirrorless) designs was their 35mm F1.2 DG DN | ART. I reviewed that lens 5 1/2 years ago, and, while it was optically amazing, it was also HUGE. It was over 136mm long (5.4″) and weighed a whopping 1090g (38.4oz). Many reviewers felt about like I did about it; they loved the images they could with it, but weren’t sure that they were willing to deal with the size and weight. I ended up buying the wonderful (and compact) Sony 35mm F1.4 GM when it came out instead.

But Sigma has really learned to prioritize cutting down the size where necessary on mirrorless, and the new 50mm F1.2 DN is much more moderate in size. It is 81mm in diameter (with a 72mm front filter thread size) and 110.8mm in length (3.2 x 4.4″). It weighs a much more moderate 740g (26.1oz). These measurements are for the Sony E-mount version (which I’m testing here), but the L mount specs are similar. That makes this lens much more similar to the Sigma 50mm F1.4 DN (78.2 x 109.5mm | 670g) than the mammoth 35mm F1.2 DN, which is 28mm longer and 345g heavier. It is very similar in size to the Sony FE 50mm F1.2 G Master, which is 87 x 108 mm and weighs 778g. That means the Sigma is just slightly longer but a fair bit narrower and actually weighs 38g less. Kudos to keeping this beast reasonably sized. I don’t have the 50mm F1.2 GM on hand, but I do own the 50mm F1.4 GM, which you can see is smaller but not dramatically so.

The Sigma 50mm F1.2 DN brings all of Sigma’s latest technologies and features together to produce a GM fighter, and the lens is (as expected) incredibly sharp as well…even at F1.2
