Introduction

The Sigma 35mm F1.4 DG DN Fine art is a designed-for-mirrorless companion to the company's first Global Vision lens, the 35mm F1.iv DG HSM Art from 2012. It's bachelor for both the Fifty-mount shared by Leica, Panasonic and Sigma, as well as for Sony Due east-mount and volition work on both full-frame or APS-C cameras.

Its 35mm focal length and bright aperture make it well-suited to weddings, events and street photography, where its smaller, lighter design relative to adapting the 2012 version to mirrorless cameras is a definite plus. And it has potential as a video lens besides, although with a caveat which we'll talk over shortly.

Available from mid-May 2021, list pricing is set up at $899.

All images edited in Adobe Camera Raw 13 with adjustments limited to white balance, exposure, highlights, shadows, white and black levels. Sharpening and racket reduction at ACR defaults.

The 'original' 35mm F1.4 Art from 2012 was designed for use with D/SLR cameras, whose sales at that point withal dwarfed those of the fledgling mirrorless market place. Information technology was subsequently modified for compatibility with Due east-mount and L-mount mirrorless cameras as well, but this compatibility came at the expense of increased weight and barrel length, to account for the decreased flange-back distance of the mirrorless systems.

By contrast, the new lens is designed specifically to take advantage of the shorter flange-back altitude of mirrorless cameras.

Information technology's non quite the night-and-24-hour interval difference we saw with the recent Sigma 85mm F1.4 DG DN Art, but it's nevertheless quite noticeable. Compared to the earlier versions of the 35mm F1.4 Art lens, this new model has shrunk past 8mm (0.3") in length, and shed a non insignificant 110-115g (3.nine-4.1 oz) in weight.

As well as the earlier lens, which remains available as of this writing for a discounted price of $799, the new 35mm F1.four DG DN has several other direct competitors. The Sigma 35mm F2 DG DN and 35mm F1.2 DG DN for example are available for both E-mount and L-mount. And for Sony shooters, the fantabulous Sony Iron 35mm F1.4 Thousand Chief lens is definitely worthy of consideration.

Sigma's 35mm F2 is more than consumer-friendly, with a slightly less vivid aperture and weather-sealing simply at the lens mount, but it's smaller, lighter and at $639, costs almost a third less.

The Sigma 35mm F1.two, meanwhile, is a lot larger, weighs nearly twice as much and at $1499 costs around two-thirds more than the F1.iv. Just you also become an even brighter aperture with shallower depth of field and a quick HSM autofocus drive.

And for Sony E-mountain shooters, the Gold Award-winning Sony Atomic number 26 35mm F1.4 GM strikes us as nearly-perfect if you can stretch to its $1399 cost-tag. Its focal length and maximum aperture are identical, but information technology's well-nigh twenty% lighter, 16mm (0.6") shorter, focuses significantly faster and matches or exceeds the Sigma's image quality in all respects.

Handling

The Sigma 35mm F1.4 DG DN Art isn't quite every bit compact and lightweight as nosotros might take expected, given that it's designed specifically for mirrorless. Compared to the original DSLR-oriented 35mm F1.four, its butt bore is near indistinguishable and its weight has only dropped by effectually 20-25 grams (0.7-0.9 ounces). Every bit noted in the previous department, the size and weight advantage versus the mirrorless variant of Sigma'south older design is rather more noticeable, yet.

Residuum of the Due east-mountain version on our Sony a7R Four body is fairly good. It's a little scrap front-heavy, largely considering while its weight hasn't fallen much, mirrorless bodies tend to be a chip lighter than DSLRs. But regardless, we didn't notice the pairing uncomfortable to shoot with. With that said, information technology might prove a bit ungainly with smaller, lighter bodies similar the original Sony a7/R.

On larger L-mount bodies like Panasonic'south S1 and S1R, the Sigma 35mm balances really nicely: you lot may find it a scrap front end-heavy on the more than petite S5, but in general, the well-sized grips on Panasonic'southward cameras aid make this lens experience a bit less heavy than information technology is.

Build quality is good, every bit nosotros've come to expect from Sigma'due south recent prime lenses. The magnesium blend-bodied 35mm F1.four feels very rugged, with a well-synthetic, premium feel. Its physical controls – and peculiarly the large, nicely-damped, buttery-smooth focus ring – reinforce that feeling.

Also as the focus ring, there are five other controls. An discontinuity band allows y'all to punch in your called aperture directly, and an unlabeled switch on the right side of the lens barrel can be used either to lock the band in its Car position or, thoughtfully, to lock it out of the Car position then yous don't accidentally stray beyond F16 into machine way.

The 'Automobile' position on the aperture ring will command aperture, well, automatically if you're in Program Auto or Shutter Priority modes, for example, merely will simply pass off aperture control to a photographic camera command dial if y'all're in Aperture Priority or full Transmission control.

On the left side of the barrel, summit to bottom, you'll discover a focus way switch, an autofocus lock button and a "Click" switch. This final tin can be used to de-click the discontinuity ring for polish, stepless aperture control. Every bit for the AF lock push button, information technology'southward customizable and can be changed to provide for various other functions, although the precise pick on offering will be dependent upon your camera body.

There's no in-lens paradigm stabilization, though this isn't an peculiarly common feature on 35mm primes (Catechism and Tamron offering exceptions hither). The Sigma does include comprehensive sealing confronting dust and wet. In all there are eleven seals, and these protect every switch, ring, button and bring together between components, likewise every bit the interface betwixt lens mount and camera body.

Up front, there's a 67mm filter thread. This is both the same size used in the SLR-oriented lens from 2012, and too a common size that should prove easy to find at an affordable toll.

It's too worth noting that the Fifty-mount variant of the Sigma 35mm F1.4 DG DN supports the company's optional USB dock, which tin can exist used both to update firmware as necessary, and to tune the speed/sensitivity of the focus band to your tastes. As of this writing, no equivalent dock accessory is bachelor for Sigma's East-mount lenses, but firmware tin can be likewise updated via the photographic camera for both E and L-mounts.

Autofocus and focus breathing

The Sigma 35mm F1.4's autofocus is driven by a stepping motor, but since it has to move only a single focusing element, focusing speeds are reasonable and focus transitions in video are very polish. Nonetheless, stills shooters used to faster, more modern linear motor speeds may be disappointed by acquisition and continuous focusing speeds.

Macro focusing is possible to a respectable minimum distance of 30 cm (eleven.8"), which is sufficient to provide a maximum magnification of 0.19x (1:5.4).

If you adopt to utilise AF to make it the ballpark and so fine-tune focus manually, yous'll be pleased to hear that direct manual focus is available at all times just by rotating the focus band, with no need to flick switches first. Of course, you can too disable autofocus entirely with the focus way switch if you want to forego AF altogether.

The only meaning bad news on the focusing forepart will be of relevance to videographers, rather than notwithstanding shooters. Unfortunately, the 35mm F1.4 DG DN exhibits quite heavy focus animate, which gives the impression that yous're zooming in and out as the focus altitude is adapted. The practiced news for video shooters, at least so long as you tin live with the focus breathing issue, is that AF is very serenity.

And in fairness, Sigma's strongest E-mountain rival, the otherwise-superb (and much more expensive) Sony 35mm F1.iv K Master besides shows significant focus breathing, albeit not quite as strongly equally in this lens. Only it still feels like a chip of a missed opportunity for Sigma to differentiate itself from its rival, and is something of an Achilles' heel on the video forepart.

Image quality

Since the launch of its Global Vision program in 2012, Sigma has built a reputation for great image quality. Every Global Vision lens is individually checked for optical defects on a custom-made, in-business firm testing rig, and that coupled with excellent optical designs has seen some of its lenses outperforming fifty-fifty showtime-party drinking glass. In most respects, the Sigma 35mm F1.iv DG DN doesn't disappoint either, with but a couple of minor concerns and very impressive sharpness fifty-fifty when shooting wide-open up.

Sharpness

ISO 100 | 1/1600 sec | F4 | Panasonic S1R

When focused in the center of the frame, the Sigma 35mm F1.four delivers great detail and fifty-fifty the corners are only very slightly softer wide open up. There'south a slight brume to the image, or loss of contrast, wide open, but stopping downward just slightly to F2.8 is sufficient to get a beautifully sharp epitome across the whole frame. Peak sharpness is reached by F4.

Alternatively, focusing in the corner does help slightly if that's where you most need sharpness and you prefer to shoot wide-open rather than stopping down a little. Put another way, any edge softness that you run across wide open in brick wall shots focused at the middle is likely irrelevant if you utilise a modern mirrorless system and identify your AF point at the precise location of your off-centre subject.

Bokeh

The 35mm F1.four DG DN'southward 11-bladed discontinuity yields nicely-rounded bokeh non just wide-open up, but even as you stop downwards to F4. And that bokeh is very clean, also, with no visible onion ring or soap bubble effects. Sigma has come a long way in ensuring that bokeh that does not appear busy even at the macro level in recent designs, and it shows; viewing the image in its entirety below, the out-of-focus background appears pleasingly smooth.

True cat's center effect is an consequence, though, yielding football game-shaped (or for not-Americans, rugby brawl-shaped) bokeh, and not but in the corners only well-nigh to the center of the frame at F1.4.

Stopping down helps, but cat's eye is e'er a factor with this lens. Depending on your tastes and subject matter, it tin either lend a dynamic look to your images or you lot may feel that it's busy and distracting.

Flare, ghosting and sunstars

Sigma includes an upgraded plastic, petal-style lens hood in the bundle with its new 35mm F1.4, and it features both a very nice, partly rubberized butt and a more than secure button-locked bayonet attachment.

Lens flare is very well controlled, merely with the sun in or well-nigh the frame, y'all can nevertheless get quite a flake of ghosting. Sunstars are quite well divers when stopped downwardly, providing a squeamish effect so long as you can live with the ghosting that comes hand-in-hand with them.

The 35mm F1.4 DG DN Art is decumbent to a piddling bit of longitudinal chromatic aberration, also known as LoCA, although this is common for about lenses of this type (and its performance is far meliorate than the original 2012-era 35mm F1.4 Art lens for D/SLR). Where it appears, LoCA presents as magenta fringing in front of the focus plane, and green fringing behind it, and these colored fringes tin can be tricky to get rid of in post-processing.

Conclusion

What nosotros similar What we don't
  • Good build quality
  • Comprehensive weather-sealing
  • Lockable, declickable aperture ring
  • Customizable AF Lock button
  • Very quiet autofocus
  • Actually sharp, even wide-open up in the corners
  • Very make clean, nicely-rounded bokeh, fifty-fifty stopped down
  • Nice sunstars
  • Slap-up flare resistance
  • Rubberized, lockable lens hood
  • Not significantly smaller or lighter than its DSLR equivalent
  • Autofocus speed is on the tiresome side
  • Heavy focus breathing
  • Slight loss of contrast wide open
  • Prone to true cat's center bokeh fifty-fifty towards the centre and when stopped down
  • Some longitudinal CA visible as magenta / green fringing
  • Prone to ghosting

Given that the Sigma 35mm F1.four DG DN Fine art is bachelor on two competing lens mounts, our last thoughts depend to some extent on which mountain you're shooting with.

Of form its prototype quality, AF performance, handling and build are essentially identical on both mounts, but the competition on each mount differs, and E-mount shooters have access to Sony's truly excellent 35mm F1.4 G Principal lens, albeit at a higher cost-tag than Sigma's rival.

Both Eastward-mount and L-mount versions of the Sigma 35mm F1.4 are very sharp lenses, and in nigh respects tin can deliver bully image quality fifty-fifty when shooting wide-open. Although there are problems with ghosting and cat's center, in many situations you'll be able to work effectually these.

And while it's mayhap a tad front end-heavy on smaller bodies, handling is otherwise excellent. We're fans of the lockable aperture ring, silky-smoothen focus ring and rubberized, lockable lens hood in particular.

A bigger business is the Sigma's modest autofocus performance, specially when compared to Sony'southward very swift-focusing G Master lens if you're an E-mount shooter. And videographers volition besides desire to bear in mind its significant focus breathing, although that's too an outcome for the Sony lens to a somewhat lesser extent.

If you're an 50-mount shooter, the Sigma 35mm F1.iv represents a very nice option for achieving a shallow depth-of-field and overall good image quality while staying on a reasonable budget. The Sigma 35mm F1.two DG DN is besides worthy of consideration, merely you lot'll have to spend a lot more and work out your biceps for the benefits it tin can bring.

But for E-mount shooters, nosotros think the Sony 35mm F1.four GM represents an even better option thanks to its smaller, lighter torso, faster AF, lack of ghosting and bottom cat's eye and fringing; if y'all can tummy the substantially higher price.

If it's simply beyond your budget, though, at that place's certainly enough to like in the crisp results delivered by the Sigma, fifty-fifty when shooting broad-open up.
