SIGMA announce the new SIGMA 14mm DG DN Art - The world's first full-frame 14mm lens with an impressive aperture. 8 Jun 2023 104PM by ePHOTOzine Sigma 14mm DG DN Art Lens in Interchangeable Lenses Bring the night sky to life like never before with the SIGMA 14mm DG DN Art, the world’s first 14mm aperture lens for mirrorless cameras*. The lens has been designed from the ground up for wideangle applications such as astrophotography, landscapes, weddings and interiors, and is available in L-Mount and Sony E-mount. Thanks to advanced chromatic aberration and coma flare control the lens delivers exceptionally impressive edge-to-edge performance across all apertures, even when shooting very challenging subjects such as the night sky. The lens has an advanced feature-set including an aperture ring with both lock and de-click functions, a customisable AFL button, a Manual Focus Lock switch, a rear filter holder, and a built-in Lens Heater Retainer to hold a heat strip firmly in place. There’s also a newly redesigned front cap that securely locks onto the lens and features two compartments for storing sheet-type rear filters. With its ultrabright aperture and ultra-wide focal length this innovative and unique optic opens up a world of creative possibilities for nightscape, landscape, cityscape and interior photographers. * As an interchangeable lens for m irrorless cameras and SLR cameras excluding fisheye lenses, correct as of May 2023 Key features The world’s first full-frame 14mm lens with an aperture The SIGMA 14mm DG DN Art is the world’s first mirrorless lens with an angle-of-view this wide. The aperture is two thirds of a stop brighter than its predecessor the SIGMA 14mm DG HSM Art for DSLRs, which means it allows 58% more light on to the camera’s sensor. This makes it even better suited to photographing the night sky, as well as for using hand-held in dark environments. Optically optimised for astrophotography With its advanced optical design that includes 1 SLD, 3 FLD and 4 aspherical elements, the lens has been designed with astrophotography in mind. With a particular emphasis on optical quality at infinity focus, the lens has very well-controlled optical aberrations and sagittal coma flare, which ensures that bright points of light remain pin-sharp and round at all apertures and across the entire frame. The lens uses in-camera optical aberration control profiles to help correct for any distortion or vignetting, whereas optical issues that are more difficult to improve digitally, such as corner softness and chromatic aberration, are eliminated by the lens’s sophisticated optical design. Using optical aberration control selectively in this way helps to keep the size and weight of the lens down. A professional feature-set with superb build quality The 14mm DG DN Art has a professional feature-set that makes it easier for photographers and film-makers to achieve the best possible results. Built in to the barrel is an aperture ring, which can be set to auto for aperture control on the camera. With a very precise action, the ring can also be de-clicked if preferred, or locked in place so that it’s not accidentally knocked. At the front of the barrel is a Lens Heater Retainer, which was a feature introduced on the SIGMA 20mm DG DN Art. This helps hold a heat strip in place, which are often used by astrophotographers when shooting in cold conditions to prevent condensation build-up on the front element. The lens features a rear filter holder that allows sheet-type filters to be attached. Soft type filters are preferred by astrophotographers as they make stars appear softer, larger and brighter. Other types of sheet-type filter can also be used. A brand-new front lens cap has been specially designed with these types of filters in mind. Two filter slots are provided to store pre-cut sheet-type filters, allowing them to be carried with the SIGMA 14mm DG DN Art lens at all times. Previous lenses such as the SIGMA 14mm DG HSM Art used a push fit type cap. The new front cap now features a secure lock mechanism to prevent the cap from falling off unintentionally. An MFL manual focus lock switch can be found on the side of the lens barrel. This allows astrophotographers to find infinity then switch the MFL switch to Lock, which completely disables the focus ring. This means that even if the ring is knocked the focus will remain at infinity. As this type of ultra-wide-aperture lens is by nature relatively heavy, attaching the camera to a tripod using the camera’s tripod thread can make the set-up front-heavy, putting the thread under stain and making the camera unstable. So included with this lens is the TS-141 Tripod Socket, which ensures a more balanced set-up closer to the centre of gravity when mounted on a tripod. An AFL button is included on the lens barrel, which can be customised depending on the camera and system. The 14mm DG DN is fitted with Sigma’s new High-response Linear Actuator HLA motor, which delivers faster, smoother, quieter and more accurate focusing than a stepping motor. This is only the third Sigma lens to be designed with this technology, ensuring very responsive focusing in all shooting situations.

SummaryThe Sigma 50mm Art is without a doubt a very high quality standard lens with autofocus for Canon, Nikon, Leica L-mount or Sony full-frame cameras. You’d expect it to out-perform the cheaper Canon EF 50mm USM and Nikkor 50mm lenses considering it’s roughly twice the price, but the big surprise is how it also delivers better performance in most aspects than the Canon EF 50mm USM and the Nikkor 58mm and is neck-and-neck with Sony's FE 50mm ZA despite both these lenses coming-in at almost twice the price. And if you’re a Leica L-mount owner, it’s a bargain compared to the 50mm options from Panasonic and especially Leica itself. When you also consider Sigma offers a service paid to switch mounts should you swap camera systems in the future, there really isn’t any reason not to get the 50mm Art if you can afford it. The only downsides are greater longitudinal chromatic aberrations than the more expensive rivals and the fact the body isn’t weather-sealed. So the Sigma 50mm Art is a very good lens, out-performing models costing even twice the price. It sets a very high bar for price / performance ratio of 50mm lenses and easily keeps our Highly Recommended award even several years after its original it now!Check prices on the Sigma 50mm Art at Amazon, B&H, Adorama, or Wex.

Sigma 50mm Art review 6th September 2019 Written by IntroIntroQualitySamplesVerdictThe Sigma 50mm DG HSM Art is a standard prime lens from 2014 designed for full-frame bodies and available in Nikon F, Canon EF, Sony E and Sigma mounts, with a Leica L-mount version arriving later in 2019. A 50mm lens delivers normal’ coverage on a full-frame body and is ideal for general-purpose use, and becomes equivalent to 75mm on APS-C/DX camera bodies 80mm on Canon, making it ideal as a short telephoto for portraiture. Its bright focal ratio is good for isolating the subject against a blurred background and is brighter by 2/3 of a stop than lenses which allows for better background isolation and shorter shutter speeds and/or lower ISO values. The Sigma 50mm Art is also compatible with Sigma’s USB dock for fine-tuning or firmware updates, and if you change bodies, you can pay to have the mount swapped for your new a member of Sigma’s renown Art series the Sigma 50mm Art is expected to perform on a very high level. It is positioned roughly between standard 50mm lenses and the top-end models from Canon, Nikon, and Sony in price. The big question then is how does it to compare to those below and above it in price? Does it offer a sufficient step-up from normal 50mm lenses to justify the price, and does it give the pricier models a run for their money? To find out, Thomas and Gordon teamed-up to give the Sigma 50mm Art a real workout and compared it against a whole slew of other lenses including the Zeiss Otus 55mm Canon EF 50mm USM, and Sony FE 50mm ZA. We’ve completely updated our original review from 2014 with test-shots on the 46MP Nikon Z7 and the 42MP Sony A7R II. So if you’re interested in which high performance standard prime lens to choose for your camera system, you’ve come to the right place! Facts from the catalogAs usual I’ll have a look at the technical data of the Sigma 50mm Art first. I’ve rated the features with a [+] or [++], when it’s better than average or even state of the art, a [0] if it’s standard or just average, and [-] if there’s a disadvantage. For comparison I use the Sony FE 50mm ZA, Nikon Z 50mm S, Nikon AF-S 50mm Zeiss Otus 55mm and Canon EF 50mm USM and simply dub them “Sigma”, “Sony”, “Z-Nikkor”, “F-Nikkor”, “Canon”, and “Zeiss” to make the comparison easier to diameter x length The Sigma is a big and long lens at 85 x 98mm x for F-mount plus 47mm for the lens hood 96mm diameter. The F-Nikkor 73 x 54mm + 32mm and Canon 74 x 51mm are small in comparison. The Zeiss is the biggest lens 92 x 117mm + 32mm lens hood. Adding the necessary adapter to mount the Sigma, Zeiss, F-Nikkor, and Canon on a modern mirrorless camera body makes those lenses even longer by around 30mm. Of the lenses already designed for mirrorless bodies the Sony is also quite large at 83 x 108 + 53mm lens hood while the Z-Nikkor at 76 x 87mm + 40mm lens hood is of medium size. [-]Weight The Sigma is a pretty heavy lens at 805g plus 43g for the lens hood only topped by the Zeiss at 945g + 64g lens hood. The Canon and the F-Nikkor are the lightest of the bunch at below 300g. The Z-Nikkor with its focal ratio of is somewhat in between at 412g + 27g lens hood. The Sony is 780g + 33g lens hood. Keep in mind though that if you want to use the Sigma, Zeiss, Canon or F-Nikkor on a mirrorless body you need an adapter which weighs another 100 to 130g or in case of the Sigma get the respective mirrorless version which weighs 910g. [-]Optics All the modern designs since 2013 are pretty complex at 12 to 13 elements in 8 to 10 groups and employ aspherical elements. Only the F-Nikkor 8 elements in 7 groups and the Canon 7/6 are much simpler designs but even the Canon employs an aspherical element. [+] Closest focus distance of the Sigma is in manual focus with a magnification of 1 The Z-Nikkor yields 1 at the same distance while the others offer a maximum magnification of around 1 at to distance. The Sigma achieves a magnification of 110 at distance. [0]Filter-thread Sigma and Zeiss 77mm, Sony 72mm, Z-Nikkor 62mm, F-Nikkor and Canon 58mm. [+]Image stabilization No lens in this comparison has an optical stabilization. But the modern mirrorless bodies from Sony and Nikon provide built-in sensor-shift stabilization. [0]Auto focus all the lenses in this comparison except for the Zeiss have a built-in AF drive. Manual-focus override is by simply turning the focus ring. The Sigma, Zeiss, Canon and F-Nikkor have a direct linear mechanical coupling between the focus ring and the focus action. They also offer the distance and dof markings that normally come with lenses designed for DSLRs. The focus ring on the lenses designed for mirrorless camera bodies operate as focus-by-wire with no distance or dof markings. The Sony has a linear gearing while the Z-Nikkor has non-linear gearing which makes smooth focus pulling almost impossible for videographers. [+]Covers full frame/FX or smaller. Same with the alternatives. [+]Price The Sigma 690 EUR / 950 USD is more expensive than the 50mm lenses from Nikon 410 EUR/USD and Canon 300 EUR / 350 USD w/o lens hood or the Z-Nikkor 360 EUR / 600 USD. But the Sigma is comfortably cheaper than the Sony 1500 EUR/USD and especially the Zeiss 3200 EUR / 3600 USD. [0]The Sigma and the Sony come equipped with a nice padded pouch, the Nikkors have flimsier pouches and the Zeiss and Canon come without a pouch at all. All lenses also have their lens hood included reversible for transport except for the Canon where you have to buy the lens hood as an extra – which I would recommend to do. [+] Sigma’s service can change the mount of the lens between Nikon, Canon, Sony, Sigma, and L-mount at a cost. This is a unique feature that no other manufacturer offers. [++]Aperture ring Only the Sony and the Zeiss have an aperture ring. The Sony with 1/3 stop clicks which can be turned off for continuous, smooth, and noise-free operation. The Zeiss offers only 1/2 stop clicks which cannot be turned off. [0]Sealing The Sigma has no weather sealing which is a shame considering its premium status. The Sony and the Z-Nikkor have special weather-sealing throughout the construction but the Sony lacks a rubber sealing at the lens-mount. [0]The score in the “features-department” is 2[-]/5[0]/7[+]. On paper only the large size and weight is on the negative side, although for the money some weather sealing would have been nice. On the positive side is the unique option to get the lens-mount standard prime lenses with Nikon mount Above from left to right Nikon Z 50mm S, Sigma 50mm Art, Zeiss Otus 55mm Sigma and Zeiss in Nikon F-mount versionThree standard prime lenses with Canon EF mount Above from left to right Nikon Z 50mm S, Sigma 50mm Art, Zeiss Otus 55mm Sigma and Zeiss in Nikon F-mount versionAlternativesThere’s no shortage of 50mm lenses on the market, and many camera and lens companies actually offer a choice of apertures too. The versions are definitely worth considering they are smaller, lighter, cheaper, less obtrusive and often deliver similar – or even superior – image quality than their bigger brothers. The loss of 2/3 of a stop may not be as relevant as the marketing literature wants you to believe. But if you absolutely want or need or brighter then you have the following alternatives with autofocus Canon offers the EF 50mm USM at 300 EUR / 350 USD or the EF 50mm USM at 1350 EUR/USD. See Gordon’s Canon EF 50mm USM review. Full-frame Canon mirrorless owners can alternatively go for the native RF 50mm at a considerable 2300 USD; see Gordon’s Canon RF 50mm USM review. Nikon has the AF-S 50mm 410 EUR/USD and the AF-S 58mm 1600 EUR/USD. See my Nikon 50mm review and my Nikon 58mm review. Sony offers the FE 50mm ZA for 1500 EUR/USD. See my Sony FE 50mm ZA review. Samyang has the AF 50mm FE for Sony E-mount only from 2016 which sells for 480 EUR/USD. Leica L-mount owners have the Panasonic offers the Lumix S PRO 50mm for 2300 USD or the Leica Summilux SL 50mm for 5300 USD, making the arrival of the Sigma a very welcome budget’ alternatives include manual focus lenses or lenses with slower focal ratios or shorter focal length Sigma has their 40mm Art for 1200 EUR / 1400 USD. The lens is huge and heavy but optically excellent. See my Sigma 40mm Art review where it earned a Highly Recommended. With its shorter focal length you have to crop 25% to achieve the same angle of view as a 50mm lens which reduces the resolution of a 46MP full-frame image to 29MP. Sony offers the FE 55mm ZA for 830 EUR / 1000 USD. It is a much smaller and lighter lens than its bigger sibling but you lose 2/3 of a stop of light gathering power and suffer some reduction in background isolation. I’ll be soon completing my Sony FE 55mm ZA review. There’s also the budget but basic FE 50mm to consider. Nikon has come out with a new standard lens for their mirrorless system, the Z 50mm S costing 360 EUR / 600 USD. See my Nikon Z 50mm review. Samyang has several manual focus 50mm lenses one of which is the 50mm AS UMC which sells for around 350 EUR/USD. The 800 pound gorilla in the group of MF lenses is the Zeiss Otus 55mm and I wish it cost 800 pounds! At a price of 3200 EUR / 3600 USD and over 900g weight plus a completely different optical design than other “normal” lenses it set a new benchmark in 2013 on optical performance in this group. See my Zeiss Otus 55mm review where it earned a Highly Recommended. Zeiss also offers the manual focus Loxia 50mm f2 and the autofocus Batis 40mm accuracy and repeatability is critical to consistently produce sharp shots especially with large aperture lenses. Repeatability the accuracy of focus on the same subject after repeated focus-acquisition of the Sigma 50mm Art is good measured in Reikan FoCal with no outliers over a series of 40 shots. There is only a very slight focus variation whether the lens focuses from a closer distance or from lens focuses in around sec on a Nikon Z7 from infinity to 110 magnification, which is not bad. On a Nikon D800 it focused even faster in sec. The Sony and the F-Nikkor move in around resp. sec. Only the Z-Nikkor is faster at sec. The focus ring has no slack/play between its movement and the focus-action and a throw of around 90 degrees, which is very short for accurate focus wide open. The focus ring has a cm wide finely ribbed rubber surface that is easy to grip and moves smoothly albeit a bit tight. The other lenses have a smoother AF operation. The focus-ring turns the same way as on Canon and Sony lenses. Unfortunately that is the opposite direction to what Nikon users have come to you record video with the built-in microphone the focus-movement produces only a slight “clack” at the start and the end of the movement and the AF-drive itself is also not too annoying. The F-Nikkor has a more irritating focus noise while focus-operation of the Zeiss, Sony and Z-Nikkor is inaudible from the outside and if you record video with the built-in microphone. As you pull focus, you’ll notice some focus breathing the image of the Sigma 50mm Art becomes 7% more magnified when I adjusted the focus from infinity to This could be distracting when shooting videos but is par for the course most other lenses in this comparison increase their magnification between 5% and 7% except for the Z-Nikkor which shows almost no focus breathing lens needed some AF micro adjustment for optimal AF on my D800 depending on the distance from the subject. Fortunately the lens can be adjusted for four different distance ranges around 40cm, 70cm, and infinity if you get Sigma’s USB dock and use their optimization pro software. But beware this is a pretty tedious process. If you only use the AF micro adjustment in your camera then go for the adjustment which best matches your typical shooting distance with this check out my quality results!

The new SIGMA 14mm DG DN Art lens on a 61-megapixel SIGMA fp L camera bodySIGMA has just released the world’s first 14mm wide-angle prime lens, the SIGMA 14mm DG DN Art. As a landscape/nightscape photographer, this lens was a dream to use. While, at this time June 2023, there are no other 14mm lenses on the market, SIGMA set the bar high in terms of image quality, build and design. In this first look article, I’ll take you through real world situations and how this lens Impressions of the 14mm DG DN ArtRight out of the box and onto the SIGMA fp L camera, I noticed how nicely it sat in my hands. The removable tripod collar is a nice touch and came in handy each time I took the lens out for a shoot. With the ability to loosen the tripod collar and rotate the camera, there is no need for an L-bracket. This makes changing compositions a breeze. With the tapered design of the lens, holding the lens in your hand while shooting feels very natural. Allowing your thumb and middle finger to easily adjust the manual aperture ring as needed. After getting a good feel for the lens, I charged the batteries in the camera and out to shoot I tripod collar is extremely useful in the field, allowing for a sturdy base and easy changes from horizontal to I am testing out a lens, I always want to see what it can do at the extremes. The SIGMA 14mm DG DN Art, being a prime lens, helped to minimize the issues most lenses face when pushed to the limit. The extreme in this case was the super wide f-stop. This is something we have never seen before on a 14mm lens. I knew this would come in great for low-light situations and night photography, but I wanted to test it in more normal settings as well. Using the lens at definitely allowed me to use super-fast shutter speeds. Even though my images were shot on a tripod, these fast shutter speeds would also allow for hand-holding in many situations if in front of this deli with the sunset behind it was a good chance to open the lens up and grab some shots to get acquainted with the lens. I focused on the brick building in the center and the lens performed very well at this distance. I was roughly 15 feet away from the doors of the deli. Everything is sharp at this 1/2000s, ISO 200 – SIGMA fp LTesting the new lens at the maximum apertureDown on the docks at the lake near my home at sunrise gave me a good opportunity to get a bit closer to my subject with the 14mm DG DN Art lens wide open. Taking full advantage of the 14mm focal length allowed me to get down low on the dock, and focus on the “B” on the back of the boat to see how the lens performed wide open at a closer range. I was surprised that at approximately 3 feet 91cm from the focus point, the lens did really well and the gradual transition from sharp to out-of-focus is very pleasing to the eye. The image is very sharp where I want the viewer to look first, and then the softness as the viewer follows the dock into the sunrise works 1/5000s, ISO 100 – SIGMA fp LI had two more tests for the SIGMA 14mm DG DN Art lens at its widest aperture. First was this gorgeous church interior in Western Kansas. Having visited these churches several times before, I knew they were open most of the time and would make a great subject to test a lens of this focal length. Most of these small towns where the churches are located are home to only a few hundred people at most. I had the church to myself and was really able to take my time and focus on the performance of the 1/60s, ISO 100 – SIGMA fp LIn this shot, I’m on the balcony looking down with my focus being dead center on the altar. Everything on the walls front to back is in seeing this incredible performance I kept my fingers crossed for clear skies later that night to put the lens to the ultimate test. Sometimes in daylight situations, the brightness of a scene can minimize imperfections. Another things to note is that when testing a lens of this caliber, these images are not cropped. This is the only way to truly show edge-to-edge performance. This brings me to my final test at Venus setting in the western sky, slight air glow to the north, this old wooden church made the perfect subject to test the SIGMA 14mm DG DN Art at night! 15s, ISO 8000 – SIGMA fp LOne of the biggest issues night photographers have is coma stretching of stars in the far corners of a star filled sky. Sometimes the coma can look like spaceships, or comets, depending on the quality of the lens. I made sure to focus on the top of the church because if there was any coma, by focusing closer, it would have magnified it in the stars. When I got home and reviewed these images on my computer, it was a breath of fresh air to see the stars in the corners are about as perfect as you can get. There is no coma even at I had to look at the other images I took to see if this one was just a fluke. It wasn’t. All the images I shot that night looked great with the lens wide 15s, ISO 6400 – SIGMA fp 20s, ISO 6400 – SIGMA fp LMore helpful features of the 14mm DG DN Art lensAnother wonderful feature of the lens is the MFL manual focus lock. Once I dialed in my focus, I could lock the focus with this switch on the side of the lens. It’s done internally so even if I accidently move the focus ring on the lens, the focus doesn’t Manual Focus Lock makes it easy to keep your focus steady, even if you accidentally move the focus in some wide-angle cityscapes was fun too. I don’t know just how close this lens can focus but it does focus pretty close. I’d say it’s less than a foot Editor’s Note minimum focus distance is inches exactly!. This allows for some really wide and cool 1/6s, ISO 3s, ISO 100The examples above show you just how clean the image is in both the top and lower portions of the single frame exposure when the lens is stopped down a bit. This could potentially eliminate the need to focus stack, depending on the shooting 25s, ISO 100Long exposures in an urban area are fun to experiment with, and thanks to the sturdy tripod foot and MFL switch, it’s easy to get sharp shots featuring lots of vibrant movement from the busy lens also has an Autofocus Lock feature and is placed right where your thumb would sit when holding the lens. This is really nice when you don’t want to switch the camera to manual focus to lock your focus. By just pressing in on the button, your focus will lock, and when you release you can re-focus like autofocus lock AFL button is easily accessible and customizable depending on the camera body you’re it is with all SIGMA Art lenses, the 14mm DG DN Art is weather sealed against dust and moisture. When it started to rain while I was shooting this image I didn’t need to be too concerned. The rain was light and didn’t last too long. Having a well built, sealed lens gives me peace of mind when the elements are not 25s, ISO 6 – SIGMA fp LThe SIGMA 14mm DG DN Art is dust and splash-resistant for use in rugged environments and inclement thing some most landscape photographers enjoy is a lens with a nice sunstar. This lens has a minimum aperture of F16 which is small enough to create a nice sunstar. A sunstar is basically the light going through the aperture and being spread out across the blades inside the lens. The number of blades in your lens will determine the number and quality of points on your sunstar. Not all sunstars are created equal, and some are much better than others. The SIGMA 14mm DG DN Art lens, when stopped down to F16, does a fantastic job with this and adds a nice element to the 1/25s, ISO 100 – SIGMA fp LFinal thoughts on the SIGMA 14mm DG DN ArtFrom the moment I opened the box, and during my time using the SIGMA 14mm DG DN Art lens in many different locations and elements, I’m not sure I can find any faults with this lens. Yes, it’s a tad on the heavy side, but when you consider the aperture and the super wide-angle of view, it has to be. Yet, it’s well-balanced and feels good when you’re shooting with it. I’m looking forward to getting out a few more times with this lens. I can think of a lot of different things to shoot with this lens, from the city to dark, desert 1/320s, ISO 1s, ISO 1/200s, ISO 200How would you use this lens to take your photography to the next level?

Gary Wolstenholme reviews this new premium 50mm lens from Sigma, with a bright f/ aperture. 2 May 2014 120PM by Gary Wolstenholme Sigma 50mm f/ DG HSM Art in Interchangeable Lenses Handling and Features Performance Verdict Specification Sigma has added to their 'Art' range of fast aperture lenses with this new 50mm f/ lens, which will be available to fit Canon, Nikon, Sony and Sigma SLR cameras. This lens costs around £850, which seems like an awful lot for a 50mm f/ lens. However, this lens is pitched as a premium optic to compete with the likes of Nikon's 58mm f/ lens, or Canon's 50mm f/ which both cost well over £1000. In this review, we'll take a look at how it performs. Sigma 50mm f/ DG HSM Art Handling and Features Those expecting a classic, compact 50mm f/ lens will be taken aback by the size and weight of this optic. It tips the scales at 815g, is almost 10cm long without the hood and takes 77mm filters. Even so, the lens balances well with the Canon EOS 5D Mk III body used for testing. Build quality is excellent, with high quality plastics with a brushed metal effect finish used for much of the lens barrel and brass used for the bayonet, which adds to the quality impression the lens conveys. However, no claims are made about the weather resistance of the lens. A silent HSM focusing motor powers the focusing mechanism, which is very quick to confirm focus and accurate, even at maximum aperture. If your sample of this lens does exhibit focusing errors, this lens supports Sigma's new USB Dock accessory, which allows focus adjustments and firmware updates to be applied to the lens, quickly and easily. Focusing is performed internally, so the 77mm filter thread does not rotate, making this lens ideal for use with polarising and graduated filters. The supplied petal-shaped hood fits to the front of the lens via a bayonet fitting. Full time manual focus can be applied by simply adjusting the focus ring at any time. Manual focusing is a pleasure as the focus ring is very smooth to operate and quite heavily damped. Closest focusing is 40cm from the sensor plane, which is fairly typical for a lens of this focal length and aperture. Sigma 50mm f/ DG HSM Art Performance As far as sharpness is concerned, this lens puts in an excellent performance, especially in the centre of the frame. At f/ sharpness in the centre is already outstanding, although clarity towards the edges of the frame lags behind somewhat. Sharpness towards the edges of the frame improves as the aperture is stopped down, reaching very good levels by f/ and outstanding levels by f/4. MTF How to read our charts The blue column represents readings from the centre of the picture frame at the various apertures and the green is from the edges. Averaging them out gives the red weighted column. The scale on the left side is an indication of actual image resolution. The taller the column, the better the lens performance. Simple. For this review, the lens was tested on a Canon EOS 5D Mark III using Imatest. Chromatic aberrations are virtually non-existent, with Imatest only able to detect fringing of a quarter of a pixel width towards the edges of the frame at f/ This is exceptional performance, which will allow shooting of high contrast subjects with no qualms or worries. CA How to read our charts Chromatic aberration is the lens' inability to focus on the sensor or film all colours of visible light at the same point. Severe chromatic aberration gives a noticeable fringing or a halo effect around sharp edges within the picture. It can be cured in software. Apochromatic lenses have special lens elements aspheric, extra-low dispersion etc to minimize the problem, hence they usually cost more. For this review, the lens was tested on a Canon EOS 5D Mark III using Imatest. Falloff of illumination towards the corners of the frame is fairly typical for a lens of this focal length and maximum aperture. At f/ the corners are stops darker than the image centre and visually uniform illumination is achieved with the aperture stopped down to f/4 or beyond. Imatest detected barrel distortion, which is virtually indistinguishable. This low level of distortion should rarely require correction, but if it does, you'll be glad to know the distortion pattern is uniform across the frame. A deep petal-shaped hood is supplied with this lens, which does a good job of shielding the lens from extraneous light that may cause loss of contrast or flare. Even when shooting into the light, contrast remains good and flare is virtually non-existent. Sigma 50mm f/ DG HSM Art Sample Photos Value For Money On paper, seeing this lens simply as another 50mm f/ lens, the £850 asking price does seem a little steep. With the performance this lens delivers taken into account it makes much more sense, representing very good value for money. For example, comparisons may be made between this lens and similar optics, like Canon's 50mm f/ which costs around £1245, and Nikon's 58mm f/ which costs around £1450. Sigma 50mm f/ DG HSM Art Verdict Overall, with this lens Sigma have created a lens which performs well in terms of sharpness and other optical attributes, for a fairly reasonable price. This combination of price versus performance will almost certainly win many fans for this lens, even despite its large size and weight for a 50mm optic. The Sigma 50mm f/ DG HSM Art is a lens that delivers outstanding performance at a reasonable price. Sigma 50mm f/ DG HSM Art Pros Outstanding sharpness in the centre at f/ Outstanding sharpness across the frame when stopped down Good build quality Virtually no CA or distortion Fast, silent focusing Reasonably priced when compared to similar alternatives Sigma 50mm f/ DG HSM Art Cons Quite large and heavy for a 50mm f/ No weather sealing FEATURES HANDLING PERFORMANCE VALUE FOR MONEY VERDICT Sigma 50mm f/ DG HSM Art Specifications ManufacturerSigma General Lens MountsNikon AFCanon EFSigma SAL-MountSony ASony E MountSony FE Mount Lens Focal Length50mmAngle of Aperturef/ Aperturef/16Filter Size77mmStabilisedNo35mm equivalentNo DataInternal focusingYesMaximum magnificationNo Data Focusing Min Focus40cm Construction Blades9Elements13Groups8 Box Contents Box ContentsFront & rear lens caps and lens hood LH830-02 Dimensions View Full Product Details Support this site by making a Donation, purchasing Plus Membership, or shopping with one of our affiliates Amazon UK, Amazon US, Amazon CA, ebay UK, MPB.
