Finally a reasonably sized Sigma ART lens (82.8mm × 96.1mm). Light-weight, too (630g).

What I see in MTF charts - astigmatism, and midframe is sharper than centre. Go figure...

Interestingly, Dustin Abbott has a review of the lens, already. In general, I'm a huge fan of his reviews as they tend to be quite unbiased and full of samples that show the non-techical part of lenses' performance (read - character). As you can read/watch here: https://dustinabbott.net/2020/08/sigma-8...rt-review/, there is a lot to like about the lens, but he does not report any issues with uneven highlights, but I find some cases where they can be distracting. Plus - double bokeh

I'm looking forward a more formal review here.

Looks great !!

Watching the Dustin Abbot video review .... I found the bokeh worse in the grass images .... micro explosions of bokeh balls ..... bubble bokeh almost ...........

The astigmatism isn't really bad there - it's no worse than on the DSLR version and better than on the Canon RF 85mm f/1.2.

Regarding the bubbles - looks bad - but does this also apply to normal viewing distances? At min focus pretty much everything goes downhill except for true macro lenses.

Interesting story about this lens.

Note: The video actually starts at time index: 15:00

Given the size, weight, price and samples at DPR the lens is great.

I would buy one, if I had something (S1R maybe) to put it on.
