I’ve lengthy been a fan of 35mm prime lenses; one was at all times glued to considered one of my DSLRs once I shot weddings and occasions, and it is an excellent focal size for environmental portraits, journalism, documentary work and journey.

So when Sigma introduced this 35mm F2 DG DN, I used to be fairly excited. The gold-award profitable 35mm F1.four Artwork is spectacular, however on the cumbersome facet (to say nothing of the heft of the also-fantastic 35mm F1.2 DG DN Artwork). For a lot of my capturing, I’d fortunately commerce a cease or so of sunshine for a package that is simpler on each my again and pockets. However are there another compromises to be discovered? Let’s discover out.

Dealing with

The included hood is made completely of metallic.

When it comes to measurement, the Sigma 35mm F2 DG DN is what I’d describe as ‘excellent.’ On Sony’s newest mirrorless our bodies, it balances fantastically, and I’d anticipate it to mainly disappear if mounted on considered one of Panasonic’s bigger S1 or S1R cameras. There’s loads of room for the clicky aperture ring, and the main target ring is admittedly properly damped.

The outside is sort of all metallic, which supplies a really stable really feel, although it could ding or dent extra readily than plastic. Alternatively, we observed no points with scratches or paint rubbing off throughout our time with it.

The remaining management level apart from the rings is the AF / MF swap on the left facet of the lens barrel. The swap materials itself is plastic, but it surely requires a great quantity of effort to toggle it from AF to MF and again once more.

You may also see the prominently featured ‘MADE IN JAPAN’ lettering inside a stylistic metallic cutout (it is only for seems, it isn’t a 3rd management ring).

I prefer it when a lot of these compact, carry-everywhere lenses are no less than considerably weather-sealed, and that is the case with the Sigma right here. There is a gasket across the mount to assist maintain moisture and mud from stepping into the digicam or lens.

Along with the included metallic hood and plastic lens cap, Sigma has included a nifty magnetized metallic lens cowl with felt backing on the facet dealing with the lens. For an added charge, they will promote you a dongle to connect it to your digicam. It is a neat contact, although the felted facet is a little bit of a fuzz magnet in the event you’re like me and maintain lens caps in your pockets.

On the entire, the Sigma 35mm F2 DG DN feels impressively well-built, and it needs to be: its $639 asking value is not astronomical, but it surely’s not precisely chump change both.

Now, nobody is anticipating to be capturing peak motion sports activities with a 35mm prime (normally), however this kind of lens wants to have the ability to sustain with youngsters and other people, significantly for occasion images. Fortunately, the Sigma 35mm F2 DG DN and its stepper motor are as much as the problem.

The Sigma 35mm F2 DG DN’s STM (stepper) autofocus motor can simply sustain animated topics.

It isn’t lightning fast, by any means, however racking from minimal focus distance to infinity in round one second (on a Sony a9 II) needs to be quick sufficient for human topics shifting at regular human velocities.

On Panasonic our bodies, the place customers could also be accustomed to even sooner focusing lenses due to these cameras’ DFD contrast-detection AF methods, the 35mm could appear slightly gradual, however once more, to not the diploma that it might be an issue.

In the event you plan to make use of the Sigma 35mm F2 DG DN for video work, bear in mind that the lens reveals important focus respiration (which means the sector of view will change noticeably as you focus the lens).

Picture high quality

It is probably not essentially the most bitingly sharp lens we have seen, however the Sigma 35mm F2 DG DN turns in fairly nice picture high quality in most respects. Even on a 61MP Sony a7R IV, which gives the very best decision you will get in a full-frame digicam on the time of this writing.


ISO 100 | F8 | 1/160 sec | Sony a7R IV

For panorama work at smaller apertures, the Sigma 35mm F2 DG DN is fairly sharp, even throughout the body at 61MP. As you progress to nearer distances and wider apertures, sharpness stays sturdy on the airplane of focus. This lens is an particularly good match for customers with 24MP cameras, and can proceed to offer good outcomes do you have to get a higher-resolution physique a while down the road.

Vignetting and distortion

Most (if not all) mirrorless lenses nowadays are designed with a point of software program corrections in thoughts. Certainly, the Sigma 35mm F2 DG DN has a built-in profile that is baked into Uncooked information from each Sony and Panasonic cameras.

That stated, the built-in profile leaves behind some distortion and vignetting (the latter of which you can even see within the picture of the leaves above) which you’ll or might not discover distracting.

On this, the best {photograph} I’ve ever produced bar none, you possibly can see that there’s some barrel distortion pushing the vertical and horizontal strains out close to the perimeters of the body.
ISO 100 | 1/125 sec | F2.8 | Sony a7R IV

As a matter of private style, I typically like having some vignetting in my photos. Distracting distortion is one other story; this seems like pretty easy barrel distortion that may very well be taken care of in publish with out an excessive amount of effort, and for one thing resembling architectural work, I’d achieve this. For photos of individuals or with out straight strains close to the perimeters of the body, I discovered it to be much less of an issue.


The bokeh, or out-of-focus traits of the Sigma 35mm F2 DG DN is likely one of the lens’ sturdy fits. As you possibly can see within the picture beneath, the out-of-focus highlights are freed from distracting onion-ring patterning, although they do have a faint ring across the periphery. The ‘cats-eye’ impact is robust, although, so if that is not your factor, greatest to take a look at different choices.

ISO 100 | 1/100 sec | F2 | Sony a7R IV

As you cease down, the cats-eye impact diminishes, and out-of-focus highlights stay spherical due to the 9 rounded aperture blades. Even at F11, you will not see the highlights taking up any kind of polygonal form. The result’s a clean background, even when it is fairly busy in actual life and also you’re capturing at a average aperture.

Whereas I may have blurred the background to oblivion through the use of a wider aperture, I needed some context to indicate that there is greater than only one bottle on a pole on this neighborhood backyard. On the identical time although, the background stays fairly clean, spectacular given how busy it’s.

Flare and sunstars

Regardless of its rounded aperture blades, the Sigma 35mm F2 DG DN is able to some respectable sunstars at its smallest apertures. Having an odd (versus even) variety of aperture blades means you get double the variety of star ‘spikes’; so eighteen in complete, and so they’re fairly well-defined if that is what you are in search of.

ISO 250 | 1/80 sec | F16 | Sony a7R IV

On the draw back, you possibly can see some distracting inexperienced flare within the decrease left nook of the body, which is an odd form and can be a ache to take away in the event you discover it troublesome. Distinction stays pretty excessive, although, even with the solar within the body. Generally capturing, the deep lens hood does a great job of retaining any flare artifacts at bay.

Lateral and longitudinal chromatic aberration (fringing)

The 35mm F2 DG DN controls lateral CA (the kind of fringing round high-contrast edges close to the perimeters of the body) rather well. On the draw back, there’s a truthful quantity of longitudinal CA (inexperienced / magenta fringing in entrance of and behind the airplane of focus) left behind.

There’s sturdy magenta and inexperienced fringing on the excessive distinction edges of the handlebars and brake cables. This could be a actual ache to take away. Click on-or-tap-through to see full-size.
ISO 100 | 1/250 sec | F2 | Sony a7R IV

As you possibly can see within the full-size model of the picture above, there may be some sturdy fringing round high-contrast edges, and in the event you look again on the bokeh part, you possibly can even see fringing in some situations in out-of-focus background highlights (which retains the already clean bokeh from being as clean because it may very well be). Whilst you may have the ability to take away the strongest fringing simply surrounding the main target airplane in publish, eliminating it on background or foreground highlights is an actual ache.

What we like What we do not
  • Good general sharpness
  • Wonderful construct high quality and really feel
  • Easy bokeh
  • Respectable sunstars
  • “Excellent” measurement
  • Colour fringing may very well be higher managed
  • Vignetting and distortion could also be a tad a lot, even with corrections
  • Flare might be distracting

In a nutshell, the Sigma 35mm F2 DG DN is a extremely stable lens for an inexpensive value. You get distinctive construct high quality, sharpness that holds up properly even on a 61MP sensor, and clean bokeh.

Sony customers may wonder if to get this or spend the small quantity of additional money for Sony’s personal FE 35mm F1.8. Whereas neither lens controls chromatic aberration (shade fringing) very properly, we have discovered that our overview copy of the Sony lens is noticeably sharper, has a sooner autofocus motor and naturally, permits a 3rd of a cease extra gentle. Alternatively, the Sigma has barely smoother bokeh and we favor its construct high quality and design. It could, although, simply come down as to if you like the customizable button on the Sony or the aperture ring on the Sigma.

ISO 100 | 1/160 sec | F2.8 | Sony a7R IV

For Panasonic L-mount customers, this Sigma lens is the one compact 35mm sport on the town – there are bigger Sigma 35mm F1.four and 1.2 Artwork choices in the event you so want, and people ought to stability fairly properly on the bigger S1 and S1R our bodies. The Sigma 35mm F2 will stability significantly properly on an S5 although, in the event you’re seeking to construct out a compact Panasonic L-mount package.

Total the Sigma 35mm F2 DG DN is simple to advocate in the event you’re available in the market for a quick, compact 35mm prime lens for all types of capturing. It is simply a top quality, good-handling lens that produces beautiful photos.
