According to test reviews on the usual photo websites, Sigma has really hit the mark with its 20mm f/1.4 Art Lens. Speaking of test reviews, if I remember well, so many reviews haven’t been published about any other Art Lens so shortly after the announcement. In any case, there’s great interest on the websites. Meanwhile in German forums you can find comments like “why is the lens so big?”, “what for do I need an f/1.4 aperture on ultra-wide lenses?”, “what pictures can you shoot with such a lens anyway?” 😉 Well, Ryuichi Oshimoto with his landscape photos shows impressively what can be done with a 20mm lens. Moreover, Marc on robertscamera.com shows why the 20mm Art has such a large aperture – with this ultra-wide lens portraits can also be shot. The only thing that’s still missing to get an overall impression of the lens is some more astro photographs. The three photos in the Flickr group (status as of 11/24/2015) are definitely not enough to be able to tell how well Sigma’s latest fast prime fares with regards to astro photos and landscape images at night. I wish you lots of fun reading and browsing. 🙂
„I admit that the tests of fixed focal length Sigma Art series lenses are becoming a bit boring. Every time you get a mechanically solid instrument with outstanding optical properties which, additionally, is sold for a sensible amount of money. When it comes to the model, tested here, Sigma went even one step further, offering original parameters which are hard to find in the line-up of other optical producers. I think there is nothing left to say…“
“The Sigma 20mm f/1.4 Art Lens is most definitely a fine example of the lens makers’ art. It performs superbly, it focuses close, it is free from flare and controls CA in a remarkable way. The price is high, but its position seems, at least for the moment, to be unique.”
“Sigma has done it again! At first, the sheer heft and size is a little shocking, especially considering it’s a prime lens. However, this shouldn’t come as a surprise given Sigma’s past Global Vision lenses. Theses lenses haven’t focused on being the smallest, or lightest, but rather the best optically. And the new 20mm ƒ/1.4 Art delivers. Images are sharp – very sharp. The lens is also very well corrected for CA and distortion, though vignetting is rather apparent, especially wide-open. The weight and front-heavy design makes it a little bit of a chore as a walk-around lens, but not overly so. All in all, this as yet unrivaled lens is the widest and brightest full-frame ultra-wide lens available, and should certainly make your short list if you’re in need of a superior ultra-wide landscape or astrophotography lens.”
“The Sigma 20mm F1.4 DG HSM is a very fast, tack-sharp prime lens in Sigma’s excellent Art series, and also a unique lens to boot, as it’s the only 20mm lens in the World to offer an f/1.4 aperture. It does exhibit some chromatic aberrations at the edges of the frame, but surprisingly little barrel distortion, whilst being able to usefully focus as close as 27cm. Vignetting at wide-open apertures is the only real optical issue of note, being very apparent when shooting wide-open, but stopping down to f/4 solves the problem altogether.
Build quality is excellent, with the brass lens mount and sober all-black design adding to the high-quality feel, and Sigma have even generously included a good fixed lens hood and padded case. Focusing was quick on the Canon EOS 5DS R that we tested the lens with, and manual focus over-ride at any time is a great feature. The only notable downsides to the design of the Sigma 20mm F1.4 DG HSM are the inability to fit circular filters thanks to its large, bulbous front element, which may be a show-stopper for some landscape photographers, the lack of any weatherproofing, and the sheer size and weight of the lens as a result of Sigma’s no-compromise approach.
Once again the price of the Sigma 20mm F1.4 DG HSM is very attractive, significantly undercutting alternative lenses from Canon and Nikon. If you can live with the lack of filter support, we can strongly recommend the new Sigma 20mm F1.4 DG HSM as a very fast, well-built ultra-wide-angle prime lens that delivers excellent image quality.”
“If you’ve read the entire review before hitting the conclusions and didn’t expect an Editor’s Choice award, you need to lay off the alcohol for a while.
The Sigma 20mm f1.4 DG HSM Art lens is sharp, contrasty, saturated, and overall delivers incredible image quality that you really can’t sit there and complain about. It’s a beautiful lens that will find its home amongst architecture photographers, street photographers, and landscape photographers. As I’m writing this review, I keep thinking about how sad I am to send it back to Sigma since the review is over. But it’s positively incredible and there is very little to hate here. Any of its flaws I wouldn’t even say I hate, I just wish that it were better in some regards. My biggest regret? I didn’t shoot this lens with a film camera.
For what this is though, Sigma is already giving you quite a bit of incredible performance and quality.”
“Overall, I feel like what Sigma has done here is incredibly impressive. Nikon, Canon and Sigma all previously have had 20mm F1.8 lenses, but nothing like the F1.4 that the Sigma now produces. Is the lens for everybody? Maybe, maybe not. I think it’ll fit into a lot more photographers kits than anybody might realize though. You never know when such a wide angle fast prime will be needed. I originally said I was afraid it would be more of a specialty offering, but that turned out to be not at all the case in that I found quite a few uses for it in everyday shooting. With that, unfortunately during my two weeks with the lens I was unable to shoot any astrophotography due to the moon cycle. I can only imagine some of the cool things people will do using this lens for astrophotography.
All said and done is the Sigma 20mm F1.4 a keeper? I think it is, and I’m probably going to SIGN UP WITH ROBERTS TO BE NOTIFIED WHEN THE NIKON VERSION BECOMES AVAILABLE. It’s not the smallest lens around as you saw above, but it is the fastest 20mm available and I can only imagine all the possibilities it’ll afford people that are interested in real wide, real shallow portraits. After the fact I wish I’d have shot more low low light stuff with the NEW SIGMA 20MM F1.4, but the Canon 5Ds that I had wasn’t really the proper tool to do that. Of course that leaves something for all of you to do when you get them. Can’t wait to see it. More Soon.”
“At the end of the day, choosing a lens is really just about user experience and image quality. This lens is heavy, yet engineered beautifully. No fault in that for me. The focus ring is great, and I would rather shoot a heavy lens with a nice focus ring, than a light lens that is terrible to manually focus.
As far as image quality, this seems to be yet another fantastic Art Series lens from Sigma. And it doesn’t look like they are showing any signs of slowing down. Sigma now has full-frame, fast primes covering 50mm, 35mm, 24mm, the wold’s fastest zoom in the 24-35mm, and several mega-zooms, and now 20mm…
I wonder when we’ll see that 85mm portrait lens?”
“Once again a top performance of Sigma and a lens that doesn’t lag behind the other lenses of the Art series.”
