Sigma 28-70mm f/2.8 DG DN Overview

The 28-70mm f/2.8 DG DN Contemporary Lens for Sony E-Mount from Sigma is a versatile wide-angle to portrait-length zoom characterized by its f/2.8 constant maximum aperture. The design suits working in available lighting conditions while affording increased control over depth of field.

Each optical surface features Super Multi-Layer and Nano Porous coatings to improve contrast and color rendering by suppressing lens flare and ghosting for optimal light transmission, and an added water- and oil-repellent coating on the front optic helps keep the lens free from smudges and droplets. The weather-sealed design benefits working in trying environmental conditions, and a nine-blade rounded diaphragm contributes a pleasing bokeh quality when using wider apertures.

  • Standard zoom for full-frame E-mount mirrorless cameras
  • 42-105mm equivalent focal length when used on an APS-C camera
  • Constant f/2.8 maximum aperture for Low light use and depth-of-field control
  • Two F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements reduce chromatic aberrations and color fringing
  • Three aspherical elements control spherical aberrations and distortion
  • Both Super Multi-Layer and Nano Porous coatings minimize lens flare and ghosting and produce contrast-rich and color-neutral imagery
  • Integrated stepping motor and optimized AF algorithm provides quick and quiet autofocus
  • 28mm minimum focus distance: 7.5", 1:3.3 magnification
  • 70mm minimum focus distance: 15", 1:4.6 magnification
  • Rounded nine-blade diaphragm for a pleasing bokeh quality

Sigma 28-70mm f/2.8 DG DN Reviews

Perfect Travel Lens Along with the Sigma 16-28

By Floyd
Rated 5 out of 5
Date: 2023-03-02

Let me start this review by saying I've been a photographer for over 50 years. I am NOT a Pixel Peeper but when it comes to lenses I know and appreciate good glass. My wife and I have several trips planned to go to Europe over the next year or so. I decided I wanted to shoot Full Frame for these trips and wanted to travel light. I had my Lumix S5 for 2 years but with the new S5 MK II with Phase Detection Hybrid AF (FINALLY) I traded it in with the 20-60 Kit Lens for the S5 MK II Body only to build a new "Travel Kit". (A side note, I never really understood that 20-60mm Kit lens, it was neither wide enough and just never long enough and at f3.5 only at 20mm, f5.6 after that, it was not very fast. I also did not like the barrel extension for such a limited range lens). I did keep my Lumix 70-300 f4.5 which is an extraordinary lens. I bought this Sigma 28-70mm f2.8 to compliment my other recent purchase of the Sigma 16-28mm f2.8. These two lenses combined give me an ideal focal range from 16-70mm in a compact, light weight form factor. Like the Sigma 16-28 here are the Pros of this lens: Compact, lightweight lens with excellent construction Includes some weather sealing at mount, enough for my needs, While traveling for pleasure I don't shoot in torrential downpours. ...who does? Super Fast, Smooth and Quiet Autofocus for both Photos and Video High magnification figure for very nice close up shots Excellent flare resistance yet it still produces decent starburst effects when wanted CA is well controlled Excellent sharpness and contrast across the frame even wide open Weight under 500g which for me is a Big PLUS Very Pleasant Bokeh The ability for the S5 MK II In-camera distortion & vignetting correction makes this lens even better. So with the S5 MK II at under 750 grams w/ Battery, the 2 Sigma lenses combined at 920 grams I've got a Travel Kit that weighs well under 4lbs. This might even make me decide to add my Lumix 70-300 to the kit. I've only take a couple of dozen test shots around our home and town and can say I am very pleased with this lens. Excellent overall quality and value!

Kind of Astonishing

I'm not big on pixel-peeping. I haven't found many surprises over the years. I once owned three different Nikon F wide-angle zooms at the same time, and try as I might I could not find much difference in the image quality among them. However, when I received a Sigma 28-70mm f2.8 DG DN from B&H a couple of days ago, I had to test it. I put a Sony A7C on a heavy Manfrotto and used my usual testbed: an entire wall of books. I tested the Sigma lens at 28, 35, 50 and 70mm -- f2.8 through f16. I didn't expect much; was surprised by the results. The Sigma gave close-to-excellent to excellent resolution ACROSS the image at 28mm f2.8, and became quickly better at the higher f-stops. I got similarly very good to excellent results across the image at 35, 50 and even at 70mm. I have never seen a lens perform better across the image. I proceeded to mount a Sony Sonnar T* FE 35mm f2.8 ZA on the camera and did the same test. I then compared the Sony results to Sigma's results when set to 35mm. To put it bluntly, the Sigma put the Sony Sonnar to shame. The Sigma's results at f2.8 were better across the image than the Sony's results were at f11. When I compared both lenses' f2.8 results, the Sony simply could not compete. It could not quite match the Sigma for crispness even at the center; in the middle areas the Sony was noticeably inferior; and at all four corners its results were downright blurry, while the Sigma remained only slightly less crisp than it was at the center. Maybe I have the world's best Sigma 28-70 f2.8 and the world's worst Sony Sonnar 35mm f2.8. I'm simply stating my surprising results.

Blown away with its quality

Great, sturdy build quality. More than happy with the images that I'm able to capture. Versatile focal length as well. Definitely recommended!

The best budget f2.8 zoom lens

By kai

Give the small size and weight, and the price, it sure has compromise. But after use it long enough I can not find a better replacement. I have used Tamron 28-75 verson one and version two, Sigma 24-70 and this 28-70. Each lens has its strong point. To me Tamron version two and sigma 24-70 has no real weakness regard image quality. But this sigma 28-70 also has some advantages. First It is the lightest f2.8 standard zoom lens. It is close to half the weight of many brand's 24-70 f2.8. And it is compact as well. Make it a great lens for long day video work. Second it has the smoothest zoom ring I ever used. Man you can really pull out some zoom in and out in video that looks like you have a servo zoom lens. It is that good feel. Tamron 28-75 is not on par at this regard. Third it looks parfocal to me. Forth it has very minimal focus breathing. Fifth the flare resistant is very good. So what is the compromise. Frst it is not 24mm. Second the dark edge is very noticeable even when I shooting video 16:9. Third and it is the almost a deal breaker to me. Miserable close up image quality at 70mm. I shoot a lot of food, I find my image looks so soft. I never had that impression when I had sigma 24-70 or tamron 28-75. So I did some quick test. Man at 70mm f2.8, the close up image quality is really bad. Even at f8 it is still not as good as other lens. From 28-50mm, the close up performance is a lot better. But consider I am a hybird shooter, video is just as important as photo.And this lens offer so many strong performance regard the video features. I just simply can not find a better replacement. You might say new sony 24-70 is better. But from reviews I watched, it is not like new Sony will surpass sigma 28-70 in every feature.

Autofocus issues

This is a great lens for the price and the size/weight makes it a great choice for travel... if you get a good copy of the lens. The specific copy of the lens I received unfortunately had some autofocus issues and it struggled to capture a sharp image. The manual focus worked great, but since I couldn't resolve the autofocus issue, I had no option but to return it. I'm guessing I most likely just received a bad copy of the lens. But, I decided not to risk it and ended up swapping it for the Tamron 28-75 instead. And, honestly, I couldn't be happier. The Tamron works perfectly and I've had no issues with image quality. Sigma has always been a favorite of mine, but I was pretty disappointed in the quality of this particular lens. It would be hard for me to recommend it to anyone based on my experience.

Terrific

The size and weight of this lens are hard to believe, even once you have it in your hand. It's also a great performer in all respects, from close focus to infinity and from wide to tele. I use it to photograph food and portraits and it is my walk around lens. I honestly can't recommend it enough. It's an absolute sleeper.

A compact lens with beautiful rendering

I love the Sigma 28-70mm. For the past 18 months I've paired it with an A7iv or A7Siii. I used it mostly in a journalistic capacity with some freelance video/photo production thrown in. Regardless of the job, I've been consistently impressed by the image quality the lens produces. It often gets compared to the Tamron 28-75mm f/2.8 (a lens which I previously owned). In my personal experience, though, I vastly prefer this lens to the Tamron. There's something special about the Sigma's rendering. It doesn't feel as sterile, as clinical as the Tamron. Is the Sigma less sharp? Maybe. But in my opinion sharper does not always equal better. The images the Sigma 28-70mm renders are consistently pleasing and I enjoy the weight, form factor and build. The focus and zoom rings are smooth and comfortable to use. One final note - I consider myself more of a 'prime guy' and prefer not to use zooms unless I have to. This lens really challenged that preference. I like the images it produces so much that I've left it on my camera in lieu of switching to some of my GM lenses. I really can't recommend it enough.

The Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Sony E uses a fly-by-wire system rather than a linear/mechanical helicoid focusing system, so you would probably want an adapter.

This is not something that can be easily quantified. The Sigma 24-70mm f/2.8 DG DN Art Lens is the better lens optically. And it has better build quality. It also gives a wider field of view. The Sigma 28-70mm f/2.8 DG DN Contemporary Lens offers the benefit of being lighter and more compact, while still being a very good lens.

This is lighter in weight versus the Sigma 24-70mm f/2.8, but not as wide. The right choice would depend on how wide you need the lens to be.

This lens is not weather sealed. It is dust and splash proof only at the mount. In comparison the heavier and more expensive Sigma 24-60 DG DN Art lens is dust and splash proof over the entire lens.
