Processed in Lightroom, minimal adjustment of exposure and white balance. Default sharpening, distortion correction on, vignetting correction on. Shot with my a7R V on my TVC-22i with an Arca-Swiss P1+. Some change in light due to the clouds passing by. Should be enough to give you an idea of performance.
The 40 pulls ahead a bit in the corners when the lenses are stopped down some.
I think this is pretty impressive considering the kind of benchmark the 40mm Art is.
At first sight the 28-45mm felt a bit redundant next to the Tamron 35-150mm f/2.0-2.8, but this result makes me think again.

I have similar thoughts, even briefly shot the Sigma against the Tamron at 35mm I think. The sigma is noticeably sharper in the outer frame at wide apertures... At smaller apertures, it was more about pixel-peeping .

The "problem":
I can shoot the 50 f/1.2 GM on my A7IV next to the EF 28mm f/1.4 Art on the Canon R5. The 28mm Art works very well on the A7IV via MC-11 as well, freeing the R5 up for the 40mm Art. When the 40mm Art is on the R5 the A7IV can also do the 85mm DN.
If I could find a satisfying 85mm for the Canon R5 this 28-45mm would make sense, as 28-45mm on the Sony next to 85mm on the Canon would be great. I have 105mm f/1.4 for my Canon, but 45-105mm is a too big gap sometimes.....
So all in all I simply fail to see any justification for this new Sigma short range zoom. And the short range zoom I really want is a 45-80 or 50-85mm f/1.8. The Tamron is nice, but from 80mm it's f/2.8 only.....

This is what I'm doing. At a recent family event, I had the Sigma 85mm on my A7rIII and the 28-45mm on my A1. It worked really well.
But now that you've mentioned the 105mm, I might want to give that a try...

Well, the 45-105mm gap won't be a problem always. And the 50 f/1.2 GM is said to be an 48mm actually, so from that perspective the gap would be almost the same....
Still, I'm not ready to sell the 50 f/1.2 GM (50mm is the focal length calling the most for a large aperture imo, and I like the AF and rendering a lot), and the same is true for the EOS R5. The GM on the A7IV and either the 105 or 28mm Art on the R5 is the approach I will stick to. It works very well, and it's not too many lens changes really. But 28-45mm + 85mm DN sounds certainly very attractive. No lens changes, less weight overall.....
There's so much great gear these days. I just wish I could mount the FE glass to RF cameras and vice versa. 28mm RF pancake + A7CII.... or 50mm f/1.2 GM or Tamron 35-150mm on the R5....

Yeah, I have similar thoughts regarding 28-45 vs fast primes. I just know that if I had the zoom, the primes would be sentenced to shelf for the most of their remaining lifes ...

I shoot mostly landscape, but it seems very snappy. I'm guessing MAubrey might be able to jump in with his thoughts. I suspect he has probably put it through its paces more.

How is the focus speed on the sigma? I assume it got the new linear motors. Also how is the accuracy of the focus?

So I just found this thread. I never intended to get this lens... But I bought it yesterday...
Love my 35 GM. Bought the 24-50 a few months back because I wanted lighter and smaller than the 24-70... Now I have a monster... Got it just to see if it will work for events (Meaning, will I deal with the weight etc....) Here's some shoddy test images since I needed to make sure the lens works before tomorrows event!! Random stuff shot wide open... I didn't get to track any moving subjects though... There's way more than needed...

AF is very accurate for video too. Trip got delayed cause covid but here's a few jpgs to show bokeh (oh, I glued on a variable ND + CPL on it for these, but didn't really notice any degradation):

So after shooting with this as my main "wide" lens for a wedding I do like it. I think if you're a 35mm shooter the 28 & 45 ends make it pretty versatile. I did pair it with the Sony 85/1.8 & 70-200 GMII which was great.
I didn't use it with a flash except for the cocktail hour and some reception. The total weight was noticeable with flash. Once dancing started I switched to the 24-50G and was instantly relieved lol. The only issue is the backwards zoom ring of the Sigma vs Sony. It will throw you off after using it all day. I wish 3rd party companies would follow the brand they're manufacturing for. I'd happily pay extra for it...

Think of it as part photography, and part workout.
I was thinking of finally breaking down and getting a 70-200 f/2.8. With Sony I could use my 1.4x TC, but my UWA is also a Sigma (14-24), so I'd have to get used to the zoom turning the other way. I could go with the Sigma, but it's heavier, doesn't take the 1.4x TC, and is probably a tad behind the Sony. Oh, and I don't think it focuses quite a closely as the Sony.
