Sigma 28-70mm f2.8 DG DN review
Summary
The Sigma 28-70mm f2.8 DG DN Contemporary provides the allure of a bright, fast aperture zoom at a more affordable price and hoy burden than traditional 24-70 2.8 models. Compared to Sigma's possess 24-70 2.8 DG DN Artistic production, the 28-70 Contemporary sacrifices those 4mm at the comprehensive-end to save roughly 20% in price and lose almost half the weight. If you'Ra satisfied by the 28-70 zero in a general lens, the Sigma DG DN is steep in the middle and only softens in the uttermost corners with the aperture wide-open, where you'll also notice darkening due to vignetting. Conclusion the aperture to f4 improves vignetting and sharpness, and by f8 the image becomes consistently bright and sharp across the frame. If you're shot closer subjects like portraits, the background rendering can glucinium attractively entire at f2.8, and spell there's textures within bokeh blobs, IT's no worse than most zooms with akin ranges. Meanwhile the build quality is fine, although it's exclusively sprinkle and moisture-sealed at the mount. Ultimately the Sigma provides a powerful alternative to larger, heavier and more expensive zooms spell maintaining decent results, but compare intimately to the likewise-specced Tamron 28-75mm f2.8.

Sigma 28-70mm f2.8 DG DN review -
- Written aside
Intro
The Sigma 28-70mm f2.8 DG DN is a all-purpose-purpose zoom lens for pregnant-redact mirrorless cameras, and at the time of writing, available in Sony e or Leica L mounts. Announced in February 2021 at a Mary Leontyne Pric of $899 surgery 759 pounds, the Sigma 28-70 provides a more low-priced alternative for those who want a walkaround zoom with an f2.8 aperture but can't stretch to pricier not to acknowledgment heavier models that zoom wider to 24mm.
Sigma loaned me a last production sample in the Sony e-climb down and in the video below I'll show you how it performs for landscapes, portraits, close-ups, and general use. If you opt to read a written version, keep scrolling!
For starters, here's the optical range in practice, starting at 28mm for standardized broad views, ahead zooming into 70mm for short telephoto reporting. By starting at 28 rather than 24mm, Sigma's been healthy to reduce the cost and weight.
The 28-70mm f2.8 Decigram DN measures 72x102mm and weighs 470g. Compare that to the 24-70mm f2.8 DG DN Art, launched just over a year earlier, which is noticeably large at 88x123mm and getting on for double the slant at 835g. The new 28-70mm also uses smaller 67mm filter threads versus 82mm happening the 24-70 Art, although is single atmospheric condition-sealed at the mount versus the whole Art lens system. Price-wise the 24-70 2.8 DG DN Art costs $1099 or 1049 pounds, making IT roughly 200 bucks or 300 pounds Thomas More pricy than the 28-70 Contemporary version. Some are significantly cheaper than Sony's have FE 24-70mm f2.8 G Master which sells for around 2000 dollars or pounds and weighs 886g.
Starting a infinitesimal less wide to save free weight and money International Relations and Security Network't a unaccustomed mind. Tamron's first native e-mount lens was the 28-75mm 2.8 Di 3 RXD launched around three years earlier and currently costing $879 Beaver State 699 pounds. Mensuration 73x118mm and deliberation 540g, it's a bitty longer and a tad heavier than the Sigma 28-70, but it's roughly in the same ballpark in size, weight and price. I've fully reviewed the Tamron 28-75, as well as the Sigma and Sony 24-70's at cameralabs.com and will update my review of the new Sigma with direct comparisons as shortly as I can.
Some the Sigma and Tamron f2.8 zooms are designed not exclusively as igniter and Sir Thomas More affordable alternatives to 24-70mm f2.8 models, but likewise as footmark-ups from budget kit up zooms like Sony's own Fe 28-70mm f3.5-5.6 which costs roughly uncomplete their price but suffers from a dimmer and variable aperture that's two whole stops slower at the womb-to-tomb-end. Okay let's see what the new Sigma's all about.
From the side the Sigma 28-70 is pretty aboveboard. A short cuspidated thrust connected the zoom along ring gets you from the wide to the long-end with the barrel extending aside 23mm. There's only one turn on the barrel which toggles between manual or autofocus, while at the remnant is a smooth assisted focalisation ring. On that point's no optical stabilisation, so anti-shake has to be provided by your body.
Sigma supplies a stupid plastic flower petal lens hood that can live fitted rearward over the barrel for transportation, piece an equally robust spring-laden cap clips onto the 67mm filter wind.
At the lens mount you'll find a rubber cringle providing some dust and wet resistance, but unlike the 24-70 2.8 Art interpretation, this doesn't extend to the rest of the lens, then use with forethought in bad atmospheric condition. This is the same plan of attack as Sigma's recent DG DN Contemporary prime lenses, not to mention Tamron's 28-75.
Instantly for focusing on the Sony A1 using a centric area and single AFS way at 70mm f2.8 and you can see there's a minor contrast-founded wobble at each focus-pull to confirm, but the process is still fairly swift and silence too. Switching the A1 to Continuous AF mode though forces the body to consumption phase-detect AF exclusively which present is refocusing perceptibly faster than before, and in my tests didn't reduce truth. So it can be worth experimenting to find the best mode.
Here's the electron lens once again at 70mm f2.8 with continuous autofocus and wide area working fine with the A1's eye spying trailing me effortlessly around the couc. Notice the almost complete absence of concentre breathing here which I'll talk about Sir Thomas More in a consequence.
70mm f2.8 isn't in particular demanding for sports operating theater wildlife, but I tried it out on the A1 with Brighton's seagulls and in these sequences you give the sack see the lens successfully trailing the eyes of the birds Eastern Samoa they swooped past at close range. Keep an eye on your chips and donuts!
In my final focus test I wanted to check for respiration where the magnification derriere depart Eastern Samoa you focus. Here's the lens at 24mm, focusing 'tween infinity and the nearest distance and back again, and patc there's a insignificant change in magnification it's fair well-behaved.
Set the lens to 70mm though and as you focus from the furthest to the closest and back again, the genus Lens is impressively bereft of breathing with the magnification essentially remaining timeless passim – great intelligence for videographers.
Now for a short range portrait test, here with the Sigma 28-70 at 70mm f2.8 where as you've seen before it's possible to achieve a decent subject breakup without completely destroying the background or context. The rendering of indistinct areas here also looks nice and smooth
If you prefer more in focus, here's how the lens looks closed one block off to f4 and even when viewing the full image I'd suppose the rendering in the setting has become noticeably busier.
Let's claim a closer attend with the f2.8 shot connected the left and the f4 version connected the right where IT's clear the f4 version looks crisper on my eyes. I think my Lens and body combination are fractionally mis-focusing at f2.8 when using optic detection, and repeating the tests didn't improve the final result. In contrast at f4 the inside information more or less my eyes get over a lot crisper, although I personally now find the rendering in the background busier and inferior attractive. To be unbiased the f2.8 version looks tight when viewed in closing off and don't forget I'm also showing you results exploitation an unforgivingly high resolution sensor, but in my portraiture tests the lens lacked the dead subject crispness of high-end lenses when nip wide-gaping.
Interpreting of blurred areas is always something I like to test and compare so here's the 28-70 2.8 at 70mm, guessing from the closest centerin space at this focal length, quoted as 38cm.
In price of the superior of rendering, there's stripped outlining, merely well-defined evidence of onion plant-ring patterns inside the blobs. IT's not perfect but to constitute fair a akin sum of onion-ringing is also visible on the Tamron 28-75 and even on the more big-ticket Sigma and Sony 24-70 2.8 models. If you prefer electric sander bokeh blobs therein kind of office, you'll be finer served by a prime lens than any of these zooms.
For one more bokeh comparison, here's the Sigma 28-70 at 28mm f2.8, as close atomic number 3 IT can focus at that focal length, quoted equally 19cm. There's still some texture within the blobs, but it's still a fairly attractive solution and I enjoyed the potential for shallow deepness-of-field effects when shooting at close stray. Remark the lens does become softer in the corners the finisher you focus.
Atomic number 3 for actual big reproduction, present's a ruler guess from as close As the lens would focus at 70mm, and at f2.8 notice how the details towards the edges have become quite soft. Closing the aperture step by step improves the abut performance only even at f8 it's still soft at the extremes. So stop downfield if you're archiving flat subjects, but if the main submit's only midmost you can get absent with larger aperture.
Zoomed to 28mm you can get surprisingly close to the subordinate and still enjoy a sharply centre, but the quality greatly deteriorates as you move towards the edges, especially at epic apertures. Closing the aperture bit by bit improves the bite away from the rivet, but on that point's still a tidy sum of optical aberration here so it's best used for subjects that are kept in the intermediate.
Now for the tone at landscape distances, starting with the lens system at 28mm f2.8, and wish totally my shots in this review, it was taken with the Sony A1 using the default option lens system corrections, so Shading and Purple-red aberration compensation set to Auto and Distortion gear up to Off.
Taking a snuggled look in the midst reveals plenty of fine details even with the aperture wide-open, and closing the aperture makes little difference to the quality.
As you move into the corners, the acuteness remains within reason duplicable, with soft only really coming into court in the very extremes. The biggest issue though is vignetting, or darkening in the corners, even with shading compensation overturned on. Shutdown the aperture one stop to f4 greatly alleviates vignetting, while closing another stop or cardinal also boosts the sharpness in the far corners.
Next here's the though at 50mm, roughly mid-room through the range, and with the aperture wide-open to f2.8.
Taking a close look midmost again reveals squeamish fine details even coupled with the high res A1 body, and closing the aperture International Relations and Security Network't necessary to further the detail.
Moving into the corners shows the electron lens is roughly maintaining a good degree of detail, although with the aperture open on that point's a little softness in the extreme corner plus close to darkening attributable vignetting. As before, closing the aperture gradually improves the quality, brightening the corners and boosting the detail. If you'Ra a picture element-peeper with a high-reticuloendothelial system body, it's definitely worth shooting elaborate views at f5.6 or f8 rather than panoramic-undetermined.
And finally here's the view at the weeklong-finish of the wander, at 70mm and again open to f2.8.
Looking closer in the central again shows modest detail which again looks pretty well out of the gate at f2.8.
Moving into the corner again shows some softness and darkening at the extremes, which as before step by step improves as you familiar the aperture. Again things are looking good across the frame at f5.6 and f8.
