Overview:

1. Best-in-class optical performance

The F2.8 Art zoom flagship zoom lens series is developed primarily to achieve superior optical performance.

As extra-low dispersion glass materials, six sheets of “F” low dispersion (FLD) glass and two sheets of special low dispersion (SLD) glass are lavishly employed while taking advantage of an optical design dedicated for mirrorless lenses. By employing three aspheric lenses, this zoom lens thoroughly subdues aberrations such as axial chromatic aberration or sagittal coma aberrations, which are difficult to correct in post-processing, tailors the resolution and achieves uniformity and superior optical performance from the center to the periphery throughout the zoom range.
In addition to Super Multi-Layer Coating, Nano Porous Coating* is employed. This lens is designed so as to be less affected by strong incident light such as flare.
The mirrorless camera-dedicated design successfully contributes to reduction in the lens size and weight.

2. Ensuring compatibility with the latest full-frame mirrorless camera bodies

The SIGMA 24–70mm F2.8 DG DN ensures compatibility with various types of the latest full-framemirrorless camera bodies tailored for L-Mount and Sony E-Mount so as to be capable of exerting the best performance under any photographic circumstances, assuming that professional or advanced amateur photographers use it.

To the AFL button, for example, various functions can be assigned from a camera body, which enhance the operability while photographing. Employing a stepping motor and the latest algorithm successfully establishes a good balance between acceleration and quietness of the AF drive. This enables stress-free focusing.

Furthermore, this lens is compatible with the Eye-Detection AF used more frequently in mirrorless cameras, which is capable of high-precision focusing at the time of portrait photography.

3. Adaptable to various uses and photographic environments

The minimum focusing distance is 18 cm at the wide-angle end. This allows you to come closer to a subject than the end of a hood to take photographs. The maximum magnifications are 1:2.9 at the wide-angle end and 1:4.5 at the telephoto end, which provides a wider range of expression by close-up photography.

Furthermore, the lens adapts to various uses and usage environments through employment of the dust- and splash-proof structure and the zoom lock mechanism for preventing the lens barrel from extending unexpectedly, and meet a wide range of needs for photography. An AF/MF switch used for the many conventional SIGMA’s lenses is also embedded in the lens barrel. Essential and basic functions are also equipped.

Looks like we're getting an alternative to the 24-70 GM soon. The rumored weight is not bad. Hopefully it works better than the GM.

It looks like it is not a DN lens but more a DSLR lens though....

. I hope I am wrong.

It's a DG DN just like the 14-24/2.8. It's smaller and lighter than the Sony 24-70/2.8 GM so it was definitely designed for mirrorless.

Thank you, Fred! Yes, it is lighter alright but only by 30g, which amounts to virtually nothing in real-life. It has the same filter diameter but it is shorter though...

The midrange zoom is the hardest to get right on a system. The Nikon Z is about as close to perfection as I've seen in the range. Will be interesting to see how well this Sigma performs. If it's like the 14-24mm then it should be fantastic.

That's the tough one to design for mirrorless as the optical design for the 35-70mm range does not benefit much from the shorter flange distance. The Sigma 14-24 was able to be very compact in comparison to SLR designs with same range and speed.

Honestly, I am curious about the Sigma 24-70/2.8 DG DN's MTF graphs. Their SLR version was not stellar but if the new E-mount performs similarly to their 14-24/2.8 and sells at $1,300, it will be hard to resist.

Sure a useful lens for many, but way to bulky / heavy for my taste.

I would much prefer a compact F4 version of this lens...

24-70/2.8 can only be so small. I would not expect miracles. The primary DG DN feature will probably be the function button and stepping motors instead of USM.

I wonder what made Sigma step into the designed for mirrorless market this late. Most folks will already have bought something in the various categories they are now starting to sell products for, seemingly being too late.
It makes me wonder whether or not this will give a real quality improvement over let's say the Tamron at a competitive price point (comparing the quality of the user experience and optical performance).

They needed to design lenses for their L-Mount mirrorless system and so the Sony system is benefiting from those efforts as well.

I didn't buy any of the GM zooms for my work, I had always the feeling that they were not that good. If Sigma does as well as their 14-24 (that I will buy soon), I could be tempted.

I always felt the same. Sony makes wonderful primes and some good zooms. The 24-70GM is probably the weakest of the GM line. It’s also not as good the new Nikon and Canon equivalents. I hope the new sigma compares favorably to these newer lenses.

I'm thinking Sony is hoping for many more new photographers getting into the Sony system. Let's not just view the world from a North American view...there are huge markets in China and India which are emerging their middle class. I would think a smaller, lighter, cheaper lens that produces great images would excel in today's world.

The leaked specs shows the E-mount version with a 56g difference in weight compared to the Sony 24-70/2.8 GM. It's also 1/2" shorter. I agree, it's not much but I'm curious on how they compare optically. The GM zoom suffers from astigmatism towards the corners.

Sigma 24-70mm f/2.8 DG DN E-mount leaked specs:
Lens construction: 15 groups, 19 elements
Angle of view: 84–34
Number of diaphragm blades: 11 (Rounded diaphragm)
Minimum aperture: F22
Minimum focusing distance: 18–38cm
Maximum magnification ratio: Wide 1:2.9-Tele 1:4.
Filter size: φ82mm｜
Dimensions (diameter x length): φ87mm × 122mm / φ3.5in. × 4.8in.｜Weight: 835g / 29.5oz.

Good to have more options, but I’ll pass due to size and weight. Would be interested in a better performing 24-70 f4 though.

Interesting. I was just looking at the 24-70GM as a lens that would work when I only want to pack one lens. I'll be watching this one closely.
