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

Autofocus issues

By Justin
Rated 3 out of 5
Date: 2022-05-17

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.

Really good quality for the price!

Sharp and surprisingly good quality pictures!

Vignette was not acceptable to me

In my experience, the vignetting was too much (both on a short and long edge) which only resolves around f/4.5. Sony vignette autocorrection (shading compensation) didn't help at all. It was a dealbreaker to me.

Sharp, Compact perfect for Hybrid shooters!

I bought this lens before selling my 24-70 GM . It's either I'm returning this or sell my GM . These are the reason why I kept this lens . Its sharper than GM and has better contrast , compact size that's half the weight of GM makes a difference carrying it all day. It's also perfect for Gimbal and I already have a Tamron 17-28 that can fill up the 24mm Edge of GM. Overall I'm very happy with this Lens except the pin cushion distortion which is fixable in LR .

Great, affordable lens

A must for any run-and-gun shooter. Great for interviews as well. Videos are sharp and the build quality on the lens itself is excellent.

Incredible

I've used a couple kit lenses and a few primes in my video work, but with the fast nature of my type of videography having a decent zoom range and fast aperture really speeds me up. I think this is a great next step in your lens purchases if you're coming up from a kit lens.

A great, cheaper alternative to the 24-70.

I wasn't aware that this lens existed, and was going to pick up the Sigma 24-70 f/2.8 until I came across this lens. Despite the difference in classification between the two lenses (Art vs Contemporary,) the quality on this lens is still astounding. Plus, the whole thing is significantly smaller which makes traveling with it much easier. The front thread size is smaller as well, which makes filters cheaper. While the rings and materials feel marginally lower quality than the 24-70 f/2.8 that my friend has, I'm glad I spotted this before biting the bullet on the Art lens. No complaints so far. Plus it has a really close minimum focus distance at 28mm, which allows me to get some really nifty shots. After filters and tax, I ended up saving more than $500 by going with this over the art, and at that price difference, the 4mm on the wide end won't be missed.

The Perfect Companion

Is this lens optically perfect? Absolutely not. The 24-70mm f2.8 DG DN Art is pretty much better at all focal lengths except at the wide end. However, this lens is really light for a mid-range zoom, and excels in some areas where the Art version does not. For photography and at normal distances, this lens is perfectly sharp from about 28mm all the way to 50mm. Image Quality is great all around the board, but I would try to avoid 70mm unless the subject is about 20 ft away from you. 70mm is usable and acceptable if you don't plan on cropping or blowing up the image for large prints. The one downside of this lens is that up-close IQ is actually quite terrible, regardless of focal length. You can stop down the aperture up close for improved results, but you won't see any improved performance at 70mm until f7.1. As for video - well this is where the lens really shines. No focus breathing at any focal length, the zoom turn is nice and smooth, and the focus ring is really quite damp and precise. Focal length doesn't matter as much when shooting video with this lens, since you're not pixel peeping when it comes to video. I love this lens for being so light and compact for full-frame bodies, and the compromises made for photography are fully acceptable. I might not use this lens for professional photography work, but for casual shoots or as a back-up zoom this lens is great. I would definitely recommend this lens for video shooters though, unless you must have the 24mm focal length.

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!

How much image quality degradation of this compared to Sigma 24-70 2.8, if any?
Asked by: Zhenpeng
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.
