sigma 50mm f 1.4 art

Sigma has recently released the new Sigma 50mm f/1.4 DG HSM ART. It also is a brand new design and it's quite an extreme design as well . Design and Build I said extreme, but how extreme is the design? How about it's 815g weight? That's almost the weight of three 50mm f/1.4 lens from either Canon or Nikon (which is around 280-290g each). Konstrukcja optyczna obiektywu Sigma 50mm f/1.4 DG HSM ART Nikon. Do budowy obiektywu Sigma A 50mm Nikon wykorzystano 13 soczewek, ułożonych w 8 grupach. Obiektyw ten został wyposażony w szkło SLD (Special Low Dispertion) o niskim stopniu załamania światła. W efekcie, generowany obraz jest niezwykle ostry i kontrastowy w całej This is a hall-of-fame lens at f/5.6. The Sigma 50mm f/1.4 DG HSM Art performed extraordinarily well in our lab tests. We actually tested it three times: once on the Canon 5D Mark III, once on the Nikon D810, and once on a beta version of the Canon EOS 5DS. The 5D Mark III results are sensor-limited, but interestingly enough the 50-megapixel Maximum Magnifications: 1:5.6. Dimensions (Diameter x Length): 85.4 x 99.9mm/3.4 x 3.9in. Weight: 815g/28.7oz.

This is an in-depth review of the Sigma 50mm f/ DG HSM Art prime lens that was announced on January 6, 2014 for Sigma SA, Canon EF, Nikon F and Sony A mounts. Ever since Sigma announced its new “Art” lens line, it has been releasing superb new lenses and updates. The Sigma 35mm f/ DG HSM Art received the highest praise from us at Photography Life, especially after we compared it to the Nikon 35mm f/ and other 35mm lenses in our extensive when I first found out that Sigma had plans to update its existing Sigma 50mm f/ EX DG HSM, I got really excited, since I knew that the new Art-series lens would not disappoint. It has been too long since both Nikon and Canon updated their 50mm f/ primes. In the case with Nikon, its newer 50mm f/ yields better sharpness than the bigger and heavier 50mm f/ In short, the Nikkor 50mm f/ is just not good enough for modern high-resolution sensors and its performance at maximum aperture is rather disappointing and the Canon 50mm f/ is quite similar in that regard. The Sigma 50mm f/ Art announcement was very timely because it hits a sweet spot between the sub-par 50mm f/ Nikon and Canon lenses, and the exotic manual focus Zeiss Otus 55mm f/ EOS 6D + 50mm 50mm, ISO 100, 1/800, f/ wanted to be upfront about its intentions with the Sigma 50mm f/ DG HSM Art – it wanted the photography world to know that the lens was not to compete with all other 50mm f/ DSLR lenses. Instead, Sigma was to compete head-to-head with the now legendary Zeiss Otus 55mm f/ known to be the sharpest standard lens on the market. When the pricing of the 50mm f/ Art was finally revealed at $950 MSRP, it became clear that Sigma’s strategy was to capture the pro-market that wanted superior performance without the hefty price of the D810 + 50mm f/ 50mm, ISO 125, 1/200, f/ shared my initial thoughts on the 50mm f/ Art back in April, with pretty high expectations after seeing the MTF performance and the price of the lens. Since the Canon EF version of the lens was released first, I was able to get a copy along with the Canon 6D about a month ago. Since then, I have taken over a thousand pictures with the lens and was able to use it extensively during my trip to London. In this review, I will focus on my experience with the lens and what I think of it so EOS 6D + 50mm 50mm, ISO 100, 1/2500, f/ biggest concern with the Sigma 50mm f/ Art was its wide-open performance at f/ Since I am not comfortable with shooting the Nikon 50mm f/ wide open, I wondered how the Sigma would do in comparison. As you will see from this review, most of the sample images were taken at f/ to demonstrate the sharpness of the lens, its subject isolation capabilities and bokeh. Some scenes were specifically shot at very wide apertures in the f/ – f/2 EOS 6D + 50mm 50mm, ISO 100, 1/500, f/ 50mm f/ DG HSM Art Specifications Mount Type Sigma, Nikon, Canon and Sony Focal Length 50mm Maximum Aperture f/ Minimum Aperture f/16 Lens Construction 13 Elements in 8 Groups Angle of View Number of Diaphragm Blades 9 Minimum Focusing Distance 40cm/ Filter Size 77mm Maximum Magnification 1 Dimensions Diameter x Length Weight 815g/ A lens hood, front & rear lens caps are included with the lensCanon EOS 6D + 50mm 50mm, ISO 100, 1/3200, f/ technical information, including manufacturer-provided MTF chart can be found in the Sigma 50mm f/ DG HSM page from our lens Handling and BuildThe Sigma 50mm f/ DG HSM is built very differently compared to previous generation Sigma lenses – it has a very nice all-metal barrel instead of a plastic barrel like on the older Sigma 50mm f/ The lens feels very solid in hands and it has a far better feel to it than the Nikon 50mm f/ which feels and handles plasticky in comparison. At 815 grams, the lens is a beast! And it had better be, with its complex optical design featuring 13 elements in 8 groups, 3 low-dispersion SLD elements and an aspherical lens element. Almost three times heavier than the Nikon 50mm f/ and only 155 grams lighter than the Zeiss Otus 55mm f/ it definitely lets itself know when mounted on a camera. It will surely make a lightweight DSLR front-heavy, although it does balance out quite well on pro-level DSLRs. Built like a tank with an all-metal exterior and a metal mount, it feels like a Zeiss-class lens that will last a EOS 6D + 50mm 50mm, ISO 100, 1/100, f/ Sigma 50mm f/ Art features a 77mm filter thread, which makes it easy to use common clear, polarizing and ND filters without having to purchase different filters or resorting to using adapter rings. The LH830-02 petal-shaped plastic hood is pretty large and does a nice job in both protecting the front element and reducing ghosting / flare. If you like using manual focus or shooting video, you will find the focus ring to be large and very smooth. Similar to all modern Nikkor lenses, the focus ring gives a bit more resistance when you get to minimum focus distance and infinity marks, and rotates past those. From my quick measurements, the distance scale seems pretty accurate and is marked for both feet and meters on top of the lens. The small plate with the letter “A” shows that the lens belongs to the “Art” category of lenses that I mentioned earlier in the review. Right next to the “Made in Japan” text on the side of the lens, there is a switch that can be used to switch from Autofocus to Manual EOS 6D + 50mm 50mm, ISO 100, 1/4000, f/ is really nothing to complain about in terms of the lens build except one area – weather sealing. While the lens itself probably can take plenty of abuse, the lens mount is not sealed with a rubber gasket like on the new Nikon lenses. This means that you have to watch out for dust between the lens and the camera mount or it will easily make it into the camera and potentially even into the lens. As I explained in my “what to do with dust inside lenses” article, it is quite normal for lenses to suck air in and out when focusing, so I recommend to try to keep the rear metal mount area clean at all EOS 6D + 50mm 50mm, ISO 100, 1/320, f/ Jordan Drake — my YouTube partner — hands me the Sigma 14mm f/ DG DN Art lens, and the first thing that strikes me is just how bulky it is. The second thing that strikes me is that we need to go shoot some astrophotography with it. Thanks to Picflow for sponsoring this episode! I am not an experienced astrophotographer, having only attempted it a few times with varying degrees of success. Once in Sedona, Arizona, where I had some beginner’s luck, once in Bend, Oregon, where I didn’t get any keepers, and a rewarding trip to Writing-on-Stone national park here in Alberta. Throw in a couple more times as part of our lens testing routine and I can safely say that I only know the basics. The real challenge is that when Jordan and I head out to take some night shots we have the worst luck with the weather. Invariably we encountered heavy cloud cover and poor timing with the moon. The Sigma 14mm test was no exception. Luckily we got a few shots to at least evaluate the lens before heading home. As I waited for night hoping the clouds would stay away, I snapped some blue-hour photos. Sigma 14mm f/ Art Design, Build Quality, and Handling Art series lenses are always built to a very high standard, and the $1,599 14mm f/ has some heft to it. Weighing in at a robust ounces 1,170 grams, you certainly notice it after a day of shooting. The Sigma 14mm is fully sealed against inclement weather and solidly machined from metal. From the integrated hood down to the control rings and switches, everything feels tight and well-built. The Sigma 14mm ART is certainly a handful. One of the best features is a locking switch for the focus, regardless of whether the camera being in automatic or manual mode. I found this especially useful in shooting the stars, as I could confirm my focus manually and then flip the switch. No matter how much the focus ring may get turned after that, I know the focus will be in the same place. This helped me to move from one shooting angle to another without worrying about my focus needing to be confirmed every time. Like all Sigma ART series lenses the controls are well-appointed. There is no built-in optical stabilizer — even though the lens seems to have plenty of space for it — which is to be expected. This lens will spend most of its time on a tripod, and even when handheld, 14mm is an easy focal length to hold steady. Due to the nature of an integrated hood and the extreme wide-angle coverage, screw-in filters are not an option. You could feasibly place large plate filters in front of the lens with an adapter or you cut gels to fit inside the lens mount. For the latter solution, Sigma has provided a template to shape your gel filters, along with a handy locking mechanism inside the lens to hold them safely in place. Here you can see not only the rubber weather sealing but also the rear-mounted gel holder. I should mention that there is a heavy-duty tripod collar included with the lens, which shifts the balance of weight appropriately backward. Not only does this balance the lens and camera better on a tripod, but it is also cut with Arca Swiss-style dovetails which simplifies attaching it to the majority of modern tripod heads. If you want to shed some weight and leave the collar at home, you are provided a simple protecting ring to cover the mounting lugs on the lens barrel. There is even a gizmo provided to attach an anti-fog lens heater. The Sigma 14mm features a powerful linear focusing motor. It’s silent and snappy. Sigma 14mm f/ Art Image Quality So let’s start with the characteristics that make for a good Astrophoto lens. We ideally want to avoid issues like “coma,” or comatic aberrations, which make your stars look like little comets at the edges of the frame. We also want to avoid sagittal astigmatism, which gives your stars a dreaded bat or bird-shaped profile. Both of these issues are very hard to remove in post. I’m happy to report that the Sigma 14mm Art handled both of these issues well. I saw no real comatic aberrations to speak of, but there was some minor sagittal astigmatism present. Shooting on the Sony Alpha 7RV, the level of detail available makes these aberrations noticeable when pixel peeping, but when viewed in the context of a photograph the issues are shown to be minor. I feel like the Sony 14mm f/ G Master handles aberrations a little better, but the Sigma gives a substantial benefit in terms of light gathering. The stars came out to play but so did the clouds. How does this lens handle shooting towards bright light sources such as the sun, or the street lights of a busy cityscape? I have always found Sigma to have excellent lens coatings that prevent sun flare and a general loss of contrast, shooting toward bright lights. The Sigma 14mm Art has no issues with ghosting or flare and carries on the excellent performance that the company has become known for. What Sigma does not traditionally deliver well, though, is sunstars. They typically have softer points, blurry rendering, and have an overall lack of drama. So one of my biggest surprises with the 14mm was just how nice the sunstars were. Although they can be small in the frame given the very wide field of view, the sunstars still spread across the frame with a sharp, tight look to them. I would happily shoot this lens in sun-drenched landscapes without hesitation. One of the best things about waiting for night to fall is the light show beforehand. We are going to be shooting this lens at f/ all the time, so it better be sharp wide open. Gratefully, the Sigma absolutely delivers sharpness, even at its widest aperture. The detail is excellent not only in the center but right to the corners as well. This is a huge boon for astrophotographers who want even detail clear across the frame. I will say there is a healthy amount of vignetting to be corrected but I was very pleased with the f/ performance. Obviously when the aperture is stopped down image quality only improves the vignetting goes away and sharpness only gets better. This is a very sharp lens. This lens delivers tons of detail across the frame. Let me preface this next part by saying that shooting astro photos will often be at the widest aperture, focused to almost infinity, but with minimal concern for the look of the bokeh of a lens. When used for landscapes, most often the lens will be shot with a stopped-down aperture, and again with minimal concern for the rendering of out-of-focus areas. I say all this because in my opinion, the Sigma 14mm doesn’t have the most pleasing rendition of bokeh. Loca and other chromatic aberrations are well controlled. In close-up shots, or situations specifically intended to show shallow depth-of-field, I find the transitions from in-focus to out-of-focus areas can look a little “nervous.” Blurry backgrounds will distort towards the corners of the image which can look distracting; an issue common on ultra-wide lenses. Specular highlights have no trace of onion rings and are pleasingly round when stopped down, but have a somewhat odd look when shot wide open. They have a more oval-like cat’s eye effect which reminds of the shape of lemons. Specular highlights are well-behaved, but look a little oddly shaped. Sigma 14mm f/ Art Video Capabilities So we have a lens that performs great wide open, corrected well for flare, with beautiful sunstars, and is tailor-made for nocturnal shoots. It also has a well-dampened manual focus ring and a de-clickable aperture. This lens should be an excellent tool for videographers. And it is in most situations. You can have a lot of fun with the unique look of a 14mm lens. The only issue the Sigma really has is in terms of lens breathing. When I first tested the Sigma 14mm, lens breathing seemed well controlled, with the edges of the frames shifting only slightly while focusing from minimum distance to infinity. However, upon closer inspection of the files, I noticed strange lens breathing in the center of the frame. This is quite rare and unfortunately very distracting when pulling focus from one distance to another. I’d still absolutely use this lens for video applications, but I would avoid long focus pulls. Nocturnal Performance That’s Lights Out Excellent optical performance coupled with professional build quality; what’s not to love? The Sigma 14mm continues the tradition of Art series lenses, delivering the goods at a decent price. Despite the larger physical size of the lens, the trade-offs are worth it. I think astrophotographers will enjoy this lens and will appreciate the faster aperture compared to some other competitors. Anyone who needs an ultra-wide lens for low-light situations like indoor music venues or documentary work might also want to take a look. Sigma has created an excellent low-light lens. There is a little Sagittal Astigmatism but no Comatic aberrations. Are There Alternatives? In L-Mount, there really isn’t much else available. Buy this lens now it’s the way to go for fast aperture ultra-wide primes. If you have a Leica or Panasonic, this is the lens to purchase. In Sony E-Mount the main competition will be the Sony 14mm f/ G Master. The Sony is smaller, lighter, and takes stunning night photos. But it is also somewhat slower than the Sigma 14mm f/ Art. If compactness for travel or back-country hiking is important, get the Sony. The price is effectively the same, and both lenses are excellent, so consider whether you want small or fast. Should You Buy It? Yes. Sigma has made an interesting focal length that is worthy of the Art badge, while also providing an excellent astrophotography lens at a decent price. The highest level of expressive performance, high-speed AF, and compactness―all combined in perfection. The new standard for “Art large-aperture standard prime. Designed with a focus on sophisticated optical performance and tremendous expressive power, SIGMA’s Art line delivers high-level artistic quality. The newest addition to the series, which has become synonymous with the Art line, is the SIGMA 50mm DG DN Art, a large-aperture standard lens designed exclusively for full-frame mirrorless cameras. While retaining the concept of the original SIGMA 50mm DG HSM Art that defined the reputation of the Art series, SIGMA has reexamined from the very beginning what is truly important in a standard lens used in a wide range of shooting situations. By incorporating all the latest technologies, this lens has achieved a high degree of compatibility between the optimum size and high-speed AF required for today's mirrorless systems, while maintaining the highest-class optical performance. In addition to the brightness of the large aperture and the large, beautiful bokeh effect, various aberrations have been optimally balanced in pursuit of uniform and balanced image quality throughout the entire image range, from the center to the edges of the frame. The result is the new "Art 50mm," a lens that is truly all-around capable in terms of expressive performance, maneuverability, and usability, and is designed to help photographers create their best work. Introducing the 50mm DG DN Art, SIGMA's ideal "standard" lens. High-speed AF for nimble and comfortable shooting The SIGMA 50mm DG DN Art is the first in the Art line exclusively designed for full-frame mirrorless cameras to adopt the “HLA” linear motor High-response Linear Actuator . In addition, by using a single double-sided aspheric lens as the focus element, the lens offers fast and quiet focusing and high tracking performance despite its large aperture. With a maximum aperture of and a high-performance AF system, the lens can be used in a variety of situations, including shooting in dark places, shooting moving subjects, snapshots, and even video. High performance, yet slim and compact The development of the SIGMA 50mm DG DN Art was focused on slimming down the lens barrel by reducing the weight of a focus lens and optimizing the lens unit layout, to pursue the "optimum size" for mirrorless systems without compromising the "maximum emphasis on optical performance" concept of SIGMA’s Art line. This lens has succeeded in achieving both top-class performance, and the size required for a light and mobile photographic tool.
