Sigma 28-70mm f/2.8 DG DN Overview

The 28-70mm f/2.8 DG DN Contemporary Lens for Leica L-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. More lightweight and compact than similar 24-70mm lenses, it's optical design incorporates two FLD and two SLD low-dispersion elements plus three aspherical elements that reduce a variety of aberrations to achieve high sharpness, enhanced clarity, and improved color accuracy. It features just one lightweight focusing element, which keeps the AF unit small. This, along with a quiet and fast stepping motor, makes for responsive and near-silent autofocus performance, an ideal combination for filmmakers looking for a high-performance, lightweight, and easy-to-handle camera system that works well with a gimbal or other accessories.

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 L-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
  • Brass bayonet for mounting accuracy and rigidity
  • Rubber sealing for dust- and splash-resistance

Sigma 28-70mm f/2.8 DG DN Reviews

Pleasantly Surprised!

I got the Sigma 28-70 for travel. I'm pleasantly surprised at how compact and lightweight this lens is! It's a great travel lens that's quick to focus and sharp. It really should be on your short list for consideration if you are looking for a travel lens - especially for hybrid shooters.

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.

Great all-around lens

This is a perfect lens for beginners...and even pros. It has great focal range and the aperture looks great at all lengths. Must-have in your bag!

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.

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

Just a good all round lens

I'm an amateur photographer and I shoot family (in a home studio with strobes, spontaneously indoors with ambient light, outside and on vacation). I previously used Sony 35 mm f1.4 GM, sigma 24-70 2.8 art and tamron 28-75 version 1. I shoot RAW. Got this lens Feb 2022 for Sony A7IV. I prioritize reasonable sharpness, fast accurate autofocus (toddlers on the run!), good color rendition (for minimal edits), versatility, good light gathering to keep ISO below 10,000 in spontaneous situations, small size and reasonable durability (I don't work for National Geographic!) Versatility and light gathering are excellent. I don't need a super zoom - I have 33MP to play with so I can crop as needed. With the great high ISO performance of my A7IV, I don't miss my f1.4 GM. And 28mm is wide enough for general purposes and even tight group selfies with a flip out screen. Color rendition and contrast are Sigma good - same as the MUCH HEAVIER 24-70 art. Maybe GM is better in terms of colors. I don't like the Tamron warm tint which I heard is unchanged in version 2. This lens is ridiculously small and light. As small as the 35 f1.4 GM. The Tamron sticks out too long. Perfect for chasing toddlers and walking with family until your legs give out. Autofocus could be slightly faster but it's accurate - but I don't feel like I've missed shots with the right settings. Same keeper rate as other lenses for my purposes. Sharpness is very good not phenomenal wide open. But too much sharpness in portraits, I've learned, can look...weird. Stopping down brings sharpness up to "professional" levels. When I shoot family portraits in my in house studio with controlled lighting, it's perfect. Just my two cents.

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!

Getting a lot of vignetting on S1R. Is it not designed for high megapixel or full frame?
Asked by: Joseph
We're sorry to hear that! The Sigma 28-70mm f/2.8 DG DN is designed for mirrorless full-frame cameras, and should not present significant vignetting. Early reviews online and our testing in the store shows roughly less than -1/3 EV at the corners at the telephoto, and slightly less at wide. If you experience more vignette than that, please reach our via video live-chat and we can try to troubleshoot with you!
