The scent of saltwater wafted over the open deck of the ferry carrying me throughout the Salish Sea. It was an overcast morning, the sunshine was dim and moody, particularly because it filtered by way of the open home windows of the boat. I used to be on my technique to photograph landscapes on San Juan Island, however the photos I ended up taking over the ferry would turn into a few of my favorites of the journey, thanks to 2 lenses seemingly purpose-built for the setting.
Vying for house in my Wandrd Prvke digital camera bag have been Sigma’s latest full-frame Artwork lenses, one mounted to a Nikon D850, the opposite a Canon 5D Mark IV. These have been huge lenses on huge cameras, and as assessment models for each weren’t accessible in the identical mount, carrying two digital camera our bodies was a necessity. The Nikon was fitted with the 28mm F1.four Artwork, a quick, wide-but-not-too-wide prime lens that provides a flexible focal size for every thing from landscapes to environmental portraits.
The Canon held the 40mm F1.four Artwork, a focal size that sits considerably awkwardly between the extra normal 35mm and 50mm. It appears Sigma is attempting to hit each doable focal size with its Artwork sequence. There at the moment are six prime lenses — all with quick f/1.four apertures — simply within the 20 to 50mm vary (and plenty of extra outdoors of it).
Sigma additionally continues to maneuver ever higher-end territory. The primary Artwork prime, the 35mm, launched at $900 and may now be picked up for as little as $650. It’s a relative discount. Each the 28mm and 40mm, nevertheless, value $1,399. The 40mm will obtain its personal assessment shortly, however for now let’s give attention to the 28mm. As a result of value, it received’t be for everybody – nevertheless it’s my new favourite wide-angle prime.
High quality and character
Sigma’s Artwork lenses have at all times been technically glorious — some are virtually too good — and the 28mm is not any exception. It’s sharp, with solely minor barrel distortion. You’ll wish to do digital correction in the event you want a superbly flat horizon, however that’s a straightforward repair. Chromatic aberration is minimal, although I did discover it within the type of purple and inexperienced fringing on the periphery of the picture or in defocused areas when capturing at wider apertures. It’s actually not prevalent in each scene, however you’ll see it on high-contrast edges, corresponding to darkish tree branches in opposition to a vivid sky or white flower petals in opposition to a darkish forest flooring. It doesn’t utterly disappear at small apertures, both, though it’s lowered and far simpler to appropriate.
Nonetheless, efficiency is nice total. That’s due to a sophisticated optical design composed of 17 parts in 12 teams. It’s a number of glass, and an extra 5 parts over the 35mm Artwork — so worth distinction begins to make sense. The lens additionally weighs practically 2 kilos, which is the worth you pay for high-quality optics. Sigma says it exams each single lens earlier than it leaves the manufacturing facility to make sure it meets requirements.
Within the age of Instagram, the place images are sometimes considered at not more than 1,080 pixels large, what issues most in a lens is just not sharpness, or some other empirical measurement of picture high quality, however character. Character is a loosely outlined time period that may imply various things to totally different individuals. And I really like what I get from the 28mm Artwork.
Sigma has transitioned from a finances purchase to premium model.
With most lenses, I often discover the candy spot to be a cease or two down from the utmost aperture. That’s not the case with the 28mm. This can be a lens you’ll want to shoot large open as a lot as you’ll be able to, although that has nothing to do with technical picture high quality.
At f/1.four, there may be important vignetting that may make topics close to the middle of the body seem to “glow” in relation to the darker corners. By Sigma’s personal admission in its printed vignette measurements, relative illumination drops to simply 20% close to the sting of the body. That’s, from a technical standpoint, not good. But it’s a lovely search for portraits and may add a moodiness to landscapes. You possibly can, after all, take away this in submit, or simply cease all the way down to f/2.eight and the lens clears itself up.

The way in which focus drops off previous the depth of discipline can be pleasing. It appears to be like “pure,” much like what I’ve seen with the Olympus 17mm F1.2 Professional, solely much more so due to the higher depth of discipline management of the full-frame format. The aperture makes use of 9 rounded blades to keep up round bokeh even when stopped down, and all the background has a slight twist to it that wraps across the topic. Along with the sturdy vignette, this attracts your eye to the middle of the body. Sure, it considerably limits your composition selections — place your topic too far off-center, they usually’ll fade into the vignette — however the look is beautiful for the fitting topics and scenes.
One of the best Sigma autofocus but
One of many causes I want to shoot stopped down quite than large open, significantly with third-party lenses, is that autofocus simply isn’t dependable at large apertures the place the depth of discipline is so shallow. However the 28mm Artwork carried out nicely. Mounted to the Nikon D850 — which, granted, has the most effective DSLR autofocus methods round — it was correct virtually 100% of the time, even in low mild. There was by no means a problem with front- or back-focusing like I’ve seen on different Sigma lenses.
The velocity of the autofocus is value stating. This lens makes use of the newest model of Sigma’s Hyper Sonic Motor (HSM), which now has an up to date algorithm for sooner efficiency. Whereas quiet, the motor has a lot torque that you could typically really feel it by way of the digital camera physique. The place some lenses slide into focus, this one jumps. I by no means seen it trying to find focus, though it would decelerate as accessible mild decreases, as will any lens.
As a result of I shot them side-by-side, I seen the 40mm Artwork was slower to focus. However I used to be capturing it on a special digital camera, so I can’t say for positive whether or not the lens or the digital camera was at fault. As for the 28mm, although, I can say it performs no less than in addition to first-party lenses on a Nikon DSLR, and that’s fairly an achievement.
Autofocus performs no less than in addition to first-party lenses on a Nikon DSLR, and that’s fairly an achievement.
That’s to not say you should have excellent outcomes each time. At f/1.four, you’re coping with a shallow sufficient depth of discipline that the topic could drift barely out of focus because of its, or the digital camera’s, motion. I might additionally prefer to see how nicely this lens performs on a Sony mirrorless digital camera with Eye AF, which I think about would make it much more correct for portraits than utilizing a manually chosen level in a DSLR focus system.
The Sigma 28mm F1.four Artwork is attention-grabbing in that, not like the 105mm F1.four Artwork, it isn’t attempting to be excellent. As a substitute, Sigma allowed it to vignette large open like we might count on from a wide-angle, wide-aperture lens. I believe that was a superb choice, though I’m positive some photographers would disagree.
However in the event you don’t like vignetting, no less than it’s simple to appropriate in submit. The chromatic aberration is a bigger drawback as a result of it’s harder to appropriate. Nonetheless, in most scenes, it received’t be an issue. You might use a smaller aperture when photographing topics with high-contrast edges to assist preserve it below management.
Whereas not excellent, that is the most effective wide-angle prime I’ve utilized in latest reminiscence, maybe ever. The autofocus is fast and pictures are sharp the place they need to be, and fantastically tender the place they shouldn’t be. It’s a traditional focal size mated with a quick aperture that collectively make for a versatile lens that’s nicely suited for a lot of duties. It’s accessible in Canon EF, Nikon F, and Sony E mounts, plus a Panasonic/Leica L-mount model will arrive later.
Are there higher alternate options?
At $1,400, it’s arduous to name the Sigma 28mm F1.four Artwork a finances possibility, nevertheless it’s cheaper than theNikon AF-S 28mm f/1.4E at an MSRP of $2,000 (typically on sale for round $1,800). It’s also lower than the opposite multi-mount 28mm f/1.four in the marketplace, the $four,990 Zeiss Otus.
Nonetheless, if a large angle with a quick aperture is what you’re after, you must also have a look at the Sigma 24mm F1.four Artwork. That is an older lens that isn’t constructed with the newest tech Sigma has to supply, nevertheless it’s been nicely acquired by reviewers and prospects alike. Oh, and it’s $849. I want the 28mm focal size as I discover it to be barely higher for environmental portraiture, however 24mm is perhaps higher for landscapes, interiors, or structure.
How lengthy will it final?
Like different lenses within the sequence, the 28mm F1.four Artwork is weather-sealed and well-made. It ought to maintain as much as years use and can doubtless outlive no matter digital camera on which it’s mounted.
Must you purchase it?
Sure, in the event you can afford it. This is among the finest wide-angle lenses I’ve used.
