Point it at distant stars and you’ll enjoy pin-sharp images right into the corners even at which means it’s also ideal for big landscape and architectural views. Approach the minimum focusing distance and you’ll enjoy some nice shallow depth of field effects, while closing the aperture down delivers sharp diffraction spikes. On top of this you’re getting a substantial weather-sealed lens with a tripod foot and a bunch of considerate features for astrophotographers. On the downside it’s a hefty lens, weighing over a kilogram and the focus breathing reveals some interesting distortions. It’s mostly unchallenged in the L-mount, but Sony owners should compare it to the 14 G Master at much the same price. In my tests the Sigma matched its optical quality, plus it’s two thirds of a stop faster and has those considerate features for astro photographers. But the Sony lens is less than half the weight, making it more flexible handheld or mounted on a modest gimbal or a small star tracker. But exacting astrophotographers will be happy to accommodate the Sigma’s heft for its larger aperture, useful tripod mount and those extra astro it now!Check prices on the Sigma 14mm DG DN Art at B&H, Adorama, WEX UK or Alternatively get yourself a copy of my In Camera book, an official Cameralabs T-shirt or mug, or treat me to a coffee! Thanks! Sigma 14mm DG DN Art review 8th June 2023 Written by IntroIntroSamplesVerdictThe Sigma 14mm DG DN Art is an ultra wide-angle lens with a bright aperture designed for full-frame mirrorless cameras. In fact it’s the fastest non-fisheye 14 to date, making it perfect for astro-photography but also ideal for dim interiors or dramatic photos and the time I made this review, it was available for Sony e and Leica L mounts, the latter working on Panasonic Lumix S bodies. Come on Canon and Nikon, your systems would really benefit from opening fully to third party lenses like in June 2023, the 14 becomes the sixth and widest DG DN mirrorless lens in Sigma’s high-end Art series, joining the existing 20, 24, 35, 50 and 85 models, all sharing the same fast aperture. In my video review below I’ll show you my full tests and results from the lens, but if you prefer to read the written highlights, keep scrolling! If you’re an L-mount owner, the Sigma 14 is pretty unique, with only Panasonic’s own 14-28 extending as wide in a true native mount, albeit as a zoom with a much dimmer also have their older 14 prime and 14-24 zoom, adapted from earlier DSLR versions and available in multiple if you’re in the e-mount system, by far the biggest rival will be Sony’s own FE 14mm G Master which arrived two years previously and costs roughly the same at around $1400-1500 or pounds. I reviewed Sony’s 14 back then and even two years later it represents tough competition, an excellent performer at a similar price. So Sigma’s new 14 better be good. In my review I’ll show you what it can do and how it things first in a World when many new lenses are touted as being smaller or lighter, the Sigma 14 is unapologetically substantial. Measuring just over 100mm in diameter and 150mm long, it makes Sony’s 14 look quite compact. More dramatic though is the weight at the Sigma is more than double the weight of the Sony, making it much less practical for handheld or gimbal work, so you really have to want that slightly brighter look at the Sony 14 in comparison. Sure it’s not quite as bright at but it sure is considerably more compact and usable realises this and pitches the 14 as being optimised for astro-photography where you’ll be shooting from a tripod. Indeed it’s supplied with a collar and tripod foot, sensibly taking the strain rather than your camera’s lens collar allows you to rotate the barrel, albeit sadly lacking any tactile feedback at 90 degree intervals. But in some consolation, the foot has an Arca-Swiss dovetail, allowing you to slide it right into a compatible clamp, and if you are handholding the lens, you can remove the collar to reduce the load a little. This reveals some mounting holes, but in the first of several small but considerate moves, Sigma supplies a rubber ring to cover them up and present a tidier-looking to the lens mount is an aperture ring from to 16 in one third increments with a lockable A position for body-based control. Like other Art lenses and the Sony, this is de-clickable for smooth and silent the end of the barrel is a very smooth and well-damped manual focusing ring, and sandwiched between this and the aperture ring are three switches and a button. From top to bottom, there’s a switch for auto or manual focus, a customisable AF Lock button, a switch that handily disables the manual focusing ring altogether, and finally the switch to declick the aperture many lenses that can be used for astro, the Sigma 14 is designed for it with a number of considerate features. You already know about the switch that disables the manual focusing ring entirely, preventing any unwanted knocks once you’ve painstakingly set it to infinity. And speaking of which, the focusing mechanism has plenty of latitude on either side to ensure you will achieve the risk of condensation during a long night of astrophotography, Sigma’s also included a ridge around the end of the barrel to help secure heating most ultra-wide lenses, there’s a built-in petal hood, but unlike the usual friction-based caps of models like the Sony, Sigma’s designed one that can actually clip onto the end of the barrel and stay in still, the spring-loaded mechanism in the cap also doubles as storage on the inside for a pair of soft filters. Yep, like most lenses with this kind of bulbous front element, the 14 accommodates filters at the mount-end and Sigma supplies a stencil for you to cut-out your own. This is no different to the Sony 14, but the ability to store a couple of these in the cap is a really nice an Art lens that’s also made in Japan, it won’t surprise you that the build quality is excellent and it’s weather-sealed throughout. So while the lens is undeniably substantial, especially with the tripod foot, think of it as being reassuringly hefty and designed to excel at a job – and while Sigma pitches it for distant astro-photography, you’ll see it also performs well in daylight, near and far, and even for vlogging if you let’s start with focusing and you’re seeing the Sigma 14 on a Sony A7 IV which I used for all my tests. This is a single AF area first in Single AFS mode where the lens is focusing very quickly and confidently without a wobble. Switch the camera to Continuous AFC mode and it looks equally good to me, and similar to the Sony 14 good measure, here’s the same test for video, again on the A7 IV in Continuous AFC mode, and again showing confident refocusing between the bottle close to the lens and the wall behind for a focus breathing test with the lens closed to f16 and manually focusing from infinity to the closest distance and back again. You’ll notice the field of view doesn’t actually change that much, but unusually that barrel distortion becomes more pronounced, making the centre appear to stretch further away. Not ideal, unless you like Warp Drive or Vertigo style special effects, but equally something you’re unlikely to come across when using the said, here’s the Sony 14 in comparison which exhibits a much more conventional reduction in the overall field of view without the stretching now for my Sigma 14 optical results and I wanted to start by showing you an image taken straight from the camera without any lens corrections, and now one with Distortion Compensation set to Auto on the Sony, which is how it’s meant to be I toggle between them, you’ll see there’s minimal correction taking place considering the extreme nature of the lens, just a mild tweak to compensate for some barrel distortion with an equally mild crop as a result. When I compare the coverage with compensation applied, it looks essentially identical to the Sony 14 so no compromise to worry this point on all my results are shown with Distortion Compensation set to Auto, again how the lens is designed to be says the lens is optimised for distant subjects like astro and I’ll be showing you some of that in a moment, but this should also make it adept at landscapes, so here’s my standard test scene, which you can compare against the same view in my other reviews. It’s angled so that details run into the looking at the lens wide-open to and if we zoom-in for a closer look in the middle of the frame where the camera was focused, you’ll see a tremendous amount of detail and there’s no significant boost to be gained by closing the out into the far corner unsurprisingly results in some darkening due to vignetting but there’s minimal loss of sharpness here, with excellent detail out of the you close the aperture one stop at a time, the vignetting quickly lifts, leaving a clean frame with a mild boost in detail at to f8. If you’re shooting a landscape, you’ll enjoy the best results with the aperture closed down a little, but the headline here is the lens performing very well at the maximum aperture. Comparing it to my results from the Sony 14 shows both lenses delivering similar detail and sharpness across the see how this translates to astrophotography, I headed up to the South Downs, the nearest darkish location to where I’m based in a five second exposure at 400 ISO with the lens wide open to where you can see the Summer sky, young Moon and light pollution of Brighton all conspiring against me, but there’s still some stars visible, and I’ve boosted the whites and highlights on the RAW file to make them detail in the middle is well-corrected as expected, and moving into the far corner also shows the stars remaining well-behaved. I’d say this is an excellent result for the Sigma lens, proving it’s a desirable option for wide-field so’s the Sony 14 seen here from the same location, albeit at a different time of year and mounted on the Alpha 1 rather than an A7 IV. Place the corner crops of the Sigma on the left and the Sony on the right, when both lenses are wide open shows little to choose between them, although with an aperture that’s two thirds of a stop faster, the Sigma will allow correspondingly shorter exposures or lower ISOs as a result. And don’t forget the physical extras on the Sigma, like the manual focus lock, wide focus range, filter holder and ridge to stop a heat strip from slipping. These all make it more desirable for astro for a quick portrait shot, taken as a selfie with the 14 of course wide-open to where you can get an idea not just of the broad coverage, but also the shallow depth of field in the closer shows the focused areas to be crisp and the blurred ones to be satisfyingly rendered, even with this potentially busy the heft of the lens, I couldn’t resist trying it out for a quick vlogging test, here using IBIS sensor shift stabilisation on the A7 IV alone, and what really struck me was the almost three dimensional look to the a steadier result, here’s some footage filmed with Active SteadyShot on the A7 IV, which takes a small crop in return for additional digital compensation. The view was so wide to start with that the cropped version is still pretty initially filmed this as a bit of a laugh, as I couldn’t imagine anyone actually vlogging with a lens this size, but the results looked so good, I repeated the test in The Lanes of Brighton, where again you’ll see the almost 3D pop of the subject with a beautifully rendered background behind again with both IBIS and Active SteadyShot, taking a mild crop to deliver smoother footage. The size and weight makes the lens less than ideal for this kind of thing, but I loved the results so wanted to show lens may be optimised for distant subjects, but still turns in respectable performance at close range. My ruler was photographed from the minimum focusing distance quoted as 30cm, where the lens has reproduced just under 30cm across the frame, and when closed to f8 here, the results are pretty crisp too right up to the this distance, the large aperture can also deliver more background blur than you might expect. Here’s my ornament test from near to the closest focusing distance with the aperture wide open, and taking a closer look reveals mostly well-behaved bokeh blobs. There’s minor textures in some of them, but it’s nothing like the onion ringing of others, and there’s no outlining to I close the aperture one stop at a time you’ll see the shapes becoming more uniform across the frame and occasionally hinting at the geometric shape of the 11-bladed comparison, here’s mild crops from the Sigma on the left and the Sony 14 on the right, both at their maximum apertures and closest focusing distances. They were taken at different times, but you can see their rendering styles are quite similar here, albeit with slightly larger blobs from the Sigma as you’d expect from its slightly larger the other end of the scale, here’s the Sigma 14 closed to f16 and pointed at The Sun, where you can see the aperture blades delivering well-defined diffraction for comparison, here’s the Sigma on the left versus the Sony on the right, both at f16 and on different days, but again you can see their diffraction spikes looking pretty similar for fun, here’s a video demo of the Sigma’s full aperture range from to 16 and back again, with the aperture declicked for smooth operation, where you can see the impact of the diaphragm system with point sources of light – albeit a slightly fuzzier one here due to the fact while Sigma is keen to tell you the lens is optimised for astrophotography, I had a great time filming with it day and night, even handheld. You’ve already seen how good it is for filming pieces to camera, but it was equally effective for huge dramatic views, and again with some opportunity for shallow depth of field effects from close prices on the Sigma 14mm DG DN Art at B&H, Adorama, WEX UK or Alternatively get yourself a copy of my In Camera book, an official Cameralabs T-shirt or mug, or treat me to a coffee! Thanks!Pages 1 2 3 “Art 50mm” for mirrorless. The new standard for artistic expression, presented by SIGMA. 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.

The reason is that I can take photos while talking to my children.

Pre-visualise the scene without having the camera to the eye Stewart Weir 50mm DG DN Art Special Impression Photography is more often about just being in the right place at the right time. The image above captures Folkestone harbour at the right time, towards the end of day as the clouds glow with the remnants last light. The SIGMA 50mm DG DN Art was the right lens needed to capture this moment. 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.
