Review: Sigma 14-24mm f/2.8 DG DN Art

Review: Sigma 14-24mm f/2.8 DG DN Art

Sigma has slowly morphed over the past several decades from a budget lens maker into one of the premier lens makers in the industry. Their Art series lenses have continually raised the bar for high quality, yet reasonably priced lenses, and their first few mirrorless-specific entries have also been outstanding. Today I’m looking at one of their newest lenses, the 14-24mm f/2.8 DG DN Art, a high-speed ultra-wide angle zoom lens that uses a new optical design from their DSLR 14-24mm lens. The result is one of the most stunning optics I’ve had the pleasure to review in the 8 years I’ve been running this site. Let’s dive in.

Before we get into the lens details, I’d like to talk about the various incarnations of ultra-wide zoom lenses. In the past 15-20 years, this range has seen quite a bit of flux. The industry has standardized pretty well on the 24-70mm range for standard zoom lenses of the f/2.8 variety, and 24-105mm for f/4, with a bit extra reach in exchange for a loss of a stop of light, but the ultra-wide segment is a bit more variable.

The traditional ultra-wide zoom has gone from 16 or 17mm to around 35mm at the long end for a while. Lenses that went even wider were a fairly rare thing, with the original Sigma 12-24mm f/4.5-5.6 being one of the early examples of the extreme ultra-wide segment. Since then, the industry has sort of moved to two extreme ultra-wide zoom ranges: the 12-24mm f/4 type lens, such as Sony’s very good 12-24mm f/4 G, and the not quite as wide, but faster 14-24mm f/2.8 range. These extreme ultra-wides fill much the same role as the traditional 16-35mm f/2.8 lens, but offer that extra width that pushes the envelope a bit, while sacrificing a bit of range on the long end, as well as the ability to use screw-in lens filters. At the end, we’ll discuss those tradeoffs with regards to this lens’ competition.

Construction and Handling

The Sigma 14-24mm f/2.8 is a lens that is both small and large, depending on your perspective. In absolute terms, the lens is fairly large and moderately hefty, with a large, bulbous front element, an approximately 5 inch length and a weight coming in at a substantial 795g. Compared with the svelte Tamron 17-28mm f/2.8, it’s nearly double the weight and a good bit larger as well, while being about 115g heavier than Sony’s 16-35mm f/2.8 GM.

However, compared to other full frame 14-24mm lenses, it’s actually quite small. Nikon’s venerable 14-24mm f/2.8 is 200g heavier and a half-inch larger in diameter, while Sigma’s own DSLR version (with a different optical design) of the 14-24mm f/2.8 is a whopping 1150g. That extra few mm of width compared to a traditional 16-35mm results in a significant increase in size and weight, but the Sigma 14-24mm DG DN manages to keep that size increase fairly manageable.

With all that said, the lens balances quite well on my A7R IV, and I was pleasantly surprised at how little the size and weight is really felt in use.

Sigma 14-24mm f/2.8 DG DN Art

The Sigma 14-24mm f/2.8 DG DN is, like all of Sigma’s Art series lenses, constructed with tight tolerances and a very solid-feeling build. The lens is predominantly finished in high-grade plastics, with the closest portion of the lens barrel constructed of metal. The fit and finish of the lens is impeccable. Most apparent of the high quality of the build is the smoothness of both the zoom and focus action. This is probably the smoothest zooming lens I’ve ever used. It’s like the lens elements are on silky, well damped rails. It’s just exceptionally smooth. The focus ring is similarly smooth and nicely damped, though like almost all E-mount lenses, it’s focus by wire. The lens includes an AF/MF switch on the side, which sits above a programmable lens button marked AFL, but this can be assigned to any function in the camera’s menus. This makes the Sigma one of the few non-Sony lenses to include the extra programmable button.

Autofocus

The Sigma 14-24mm f/2.8 is a native E-Mount lens, and overall it focuses like one. The lens focuses quickly and accurately in continuous AF. In single-shot AF, the lens isn’t a speed demon, with a fairly deliberate focus action before locking. I’m not sure why it’s notably slower in single shot than it is in continuous, but it’s definitely something I noticed. In practice, for this type of lens, that more deliberate single-shot AF isn’t an issue, but it’s worth shooting in C-AF if focus speed is of prime importance.

Filters

This is not a normal section in my lens reviews, but given that those in the market for a top-notch ultra-wide often need filters, it bears discussing. Because of the extremely wide 14mm focal length and the resulting bulbous front element, the Sigma 14-24mm f/2.8 can’t take traditional screw-in filters. This is true of essentially all lenses that are 14mm or wider, but it is definitely a down side. I am one who uses a polarizing filter quite often, as I shoot a lot of waterfalls around Ohio, and a polarizing filter can help to dramatically cut glare from wet rocks.

As such, I have employed one of the few external filter systems available for the Sigma 14-24mm. In my case, I’m using the Nisi S5 filter holder with their 150mm round landscape filter. I’ll give a quick overview of this filter system for those who may be interested in using external filters with the 14-24mm. The Nisi S5 is not a cheap, nor discreet solution. It uses 150mm round polarizing filters (and 150x150mm square filters if using the square filter holder), and the holder with a polarizer costs between $450 and $500 depending on which polarizer you get. As such, if you need a polarizer regularly on a lens like this, be sure to count the cost of a filter system into your decision-making process.

Despite the large size of the filter holder, if using just the round polarizer, you can utilize the Nisi 150mm filter cap to protect the filter while mounted to the holder, and add any generic 100mm slip on cap on the rear opening to protect the system and filter. With the filter protected, I can fit the whole thing in the front pocket of my shoulder bag, making it no less convenient than a screw in filter.

The Nisi S5 system is quite easy to use in the field, and can be attached with ease in a matter of seconds. You simply slide the opening at the rear of the filter holder over the hood, with the four small alignment tabs towards the indented parts of the lens hood. This alignment is shown below without the filter installed, but you can attach it without removing the polarizer if needed.

You then simply tighten the rear locking ring by rotating it about 30 degrees, which locks evenly around the hood. A thumb screw is present as well, which doesn’t attach the holder to the lens, but rather prevents the unlocking ring from moving and accidentally unlocking the holder from the lens.

With the polarizer installed, the filter system does not vignette at all, even at 14mm. The polarizer can be rotated by either of the two geared wheels, which move smoothly and precisely for setting polarization. Though not shown in the images here, the holder also comes with a square filter attachment which very quickly snaps on to the outer portion of the holder with a spring-loaded knob. Two square 150mm x 150mm filters, such as neutral density or graduated neutral density filters can be slid into the square holder. The square holder can then be rotated as well, and the rotation is independent of the polarizer rotation. It’s a slick system, though you pay for it.

It’s also worth noting that Sigma has a nice flip-lock system for securing rear filters, which can be very useful for using neutral density filters. The lens includes a template for cutting ND film gels to fit this rear filter slot, though a few filter makers have created optical glass rear filters for the Sigma 14-24mm. I use the Kase glass filters. They’re a little fiddly to install, but work well, with essentially zero impact image quality. Be sure to watch the thickness of the rear filters, though. Try to stick to filters that are 0.3mm or thinner, as thicker filters start to induce substantial field curvature, which can negatively affect edge sharpness.

    Hello Jordan,
    I contacted you yesterday regarding the Sigma 14-24 and the Tamron 17-35. Your review definitely makes clear which you find is best and I take that to mean, in particular, when they are challenged by a 60MP sensor! That still doesn’t totally answer my question from yesterday: Is the Tamron, in its own right, up to the 60MP demands. Seeing you use some images from it in your Sony A7R-IV review sort of says “YES”. But after reading the Sigma review, I almost read a “No”. Hope you are following.

    45 to 55 years ago I was involved in the Redwood National Park creation and later its expansion. I donated over 5,000 images to them. They have just awarding me a very small contract to revisit a few places I can still access and show how the landscape has changed over a 50+ year time. It is unusual I think that the same photographer (now at 77) can once again photograph places within the park that only I and a few others saw before they were often compromised by logging, etc. before being protected. Can still hike 10-12 miles and 2-3,000 foot elevation elevation changes in a day hike, so still in decent shape.

    I used a Hasselblad 500C, Nikon F and even a 4×5 briefly to do that early work. So I’m planning on acquiring the Sony A7R-IV for the camera and still deciding on lenses. (Current camera is aging Fujifilm X-Pro 1 and I believe a very good sample of the 18-55 F/2.8-4 lens). I’ve created numerous panorama shots in portrait orientation at 18mm that look quite good. I believe the Sigma could give me great “breathing” room in tight quarters!

    You do not mention 2 other aspects of the 14-24 Sigma I’d love to hear about: using both camera & lens in wet conditions and using it in APS-C crop mode, where you could get 36mm at 26MP.

    Thank you for taking time to guide me here.

      For your first question, is the Tamron up to the 60 Megapixel demands? The answer is: Mostly. Over the majority of the image frame, it is definitely up to the task. Only at the edges and corners of the frame does it falter a bit on the A7R IV. It’s still ‘good’, it’s just not ‘great’ there. For most shots, it will make a pretty negligible difference, unless you’re printing huge and have detail at those edges. Even then, again, it’ll be fine, just not the biting sharpness at the edges that the Sigma gets you. I switched from my Tamron because the Sigma was able to basically quell my search for one of the ultimate landscape primes, since it performs as good or better than them anyway. It’s also wide enough that I was able to swap both my Tamron and my Voigtlander 12mm and 21mm f/3.5 and not really feel like I was losing anything at all, and was in fact gaining a image quality in the process (though I also added a Voigtlander 15mm, which I will use when I want to travel with three small primes….15, 40, 90…using APS-C mode when needed for 22., 60 and 135mm).

      I haven’t used the lens in wet conditions (and I don’t generally shoot much in the rain.) The Sigma does have a rubber gasket on the mount and promises weather sealing, but I take all of those claims from any manufacturer with a grain of salt.

      In APS-C mode, it works great. The lens can easily resolve the density of the A7R IV sensor, so it looks fantastic in APS-C mode. (I accidentally turned it on at one point in one of my shoots, such that one of the sample images is in APS-C mode).

    What lenses are your other small primes ?

    15mm Voightlander
    40 ?
    90 ?

    1. Jordan Steele Avatar

      Yes, the 15mm Voigtlander (review coming at some point), Voigtlander 40mm f/1.2 and Contax G 90mm f/2.8.

        Ahh I figured the 40 was a Voigtlander could not figure out the 90.
        Thought it might be the macro lol

    I like my 16-35 F4. Light, takes filters. Cheaper and I like the images that come out of it on my A73

    1. Jordan Steele Avatar

      The 16-35mm f/4 is a good lens, though it is only $50 cheaper. The 16-35 gives a nice range and is more convenient with use of filters, but it isn’t in the same league optically. I owned the 16-35mm f/4 for several years, and sold it for the Tamron 17-28mm, which was notably better than the 16-35mm at the edges of the frame, and the Sigma 14-24mm is yet another step up over the Tamron. The Sigma is sharper at f/2.8 at the edges throughout the shared focal range than the Sony 16-35/4 is even at f/8. These differences may not be majorly important when shooting on a 24MP body like the A73, though they would be noticeable (I could see a difference between the Tamron and Sony when I was shooting with the A73), and the Sony 16-35mm is definitely quite good at the wide end of the range when stopped down a little. On a higher megapixel body, however, the difference between the Sony and Sigma would be rather substantial.

      With all that said, the Sony 16-35mm is a very nice lens and is certainly capable of creating great images. I used mine to great effect for about 4 years, and really liked it. Buying new now, I’d lean towards the Tamron if you want a smaller lens that takes screw in filters, or the Sigma for the wider field of view and the best optical quality.

    Have you had any issues with the Kase rear filters breaking?

    1. Jordan Steele Avatar

      I have not as of yet, though I have seen several reports of people who have had it happen. To be fair, I also have only used them a handful of times so far. We shall see in the long term.

    Thanks for the review.

    Sigma has another UW lens 14mm f1.8. How would you compare both lenses for Leica SL?

    1. Jordan Steele Avatar

      Unfortunately, I haven’t had a chance to try out the 14mm f/1.8, though I’ve heard good things. This is just my impression from reading the reviews of others, but from what I have heard, the 14-24mm is sharper than the 14mm f/1.8 and has better chromatic aberration control. The f/1.8 is f/1.8, though. I think if your prime reason for buying a lens in this width is for astrophotography, the f/1.8 aperture of the prime may well serve you very well, but outside of that, I don’t see a lot of reasons to go that route. You really don’t gain anything outside of lens speed, and you lose the 15-24mm range, lose a little sharpness and gain a fairly hefty amount of weight, as the 14-24mm is significantly smaller and lighter.

    Thank you for the thorough review, Jordan. I just acquired the Sigma 14-24 from Guy on Fred Miranda. I have never used filter holder before. I am not interested in using the rear filter slot. So you have the NISI S5 holder and their CPL, which ND filters did you get?

    Thanks,

    Douglas

    1. Jordan Steele Avatar

      I’m using the Kase rear filters right now for NDs. Mine haven’t broken yet, but from what I’ve seen, it’s likely only a matter of time. I do have the new Aurora magnetic rear filters coming soon, which should be super easy to swap on the rear, and more robust with the magnetic frame. I don’t plan on purchasing a front ND filter to us with my Nisi S5 system, as I like just having the threaded CPOL with the NISI cap on it, so I can shove it in my bag and not worry about the square filter holder.

      I can’t believe Guy actually sold his 14-24…he was super high on it…but he doesn’t keep many lenses for that long.

    This is an excellent review. Thank you for info on the Nisi filter holder. This is exactly the type of review that I was looking for. I have the rear attachable ND Filters, but the polarizing lens with the Nisi is what I’m after. I read some negative reviews about the Nisi and was very indimidated to buy. After seeing your review, I think Im going to give it a try. Thank you for an excellent thorough examination of the 14-24 DG DN Art for sony A7IV. I have the same setup, and am very excited that this has worked well for you.

    Hello!

    I have been endlessly searching for the optimal lens for real estate photography/videography. $1300 was certainly way above what I could afford but I was willing to invest and sacrifice for the future. I went back and forth with Sony 16-35 f2.8 GM, Sony 16-35 f4, Tamron 17-28 f2.8 and I couldn’t make a decision which lens to get until I came across Sigma 14-24 f2.8 and read so many promising reviews that I jumped to conclusion quickly and purchased it. Now, I have been concerned after coming to the realization that although this lens has exceptional image quality, sharpness and all the rest, when it comes to real estate photography/videography, from what I have been reading, it is vital to have a polarizing filter to remove reflections off the floors etc.

    What should I do? GM is very expensive but is able to attach polarizing filters, I don’t want to compromise image quality for going with a lesser quality lens. I guess my question is what is the best lens for real estate photography/videography when all things are considered?

    Thank you for your time!

    1. Jordan Steele Avatar

      This is definitely a personal decision. The cheapest option is to pick up an external filter holder for your 14-24mm such that I discuss in this review (see first page discussion). I use the Nisi S5 filter holder with their 150mm circular polarizer, and it works very well. The filter is obviously very large and expensive, but it attaches quickly in the field and has been easier than expected. However, the 16-35mm GM is going to give you still very good image quality and the filter situation is definitely more convenient. You do lose 2mm of width, which may be important to you for real estate photography.

    Hi there – Thanks for the review. Any way you can link to the filter adapter and holder? I have a 150mm ND already but need the adapter and 150m holder. Its crazy, but cant find them! Thanks
