I am far less bother by the CA than the transition zone. I really only associate super clean CA correction with monster lenses in this FL.
Maybe Sigma chose this very balanced lens at this common FL to appease the common desire (or obsession) with sharpness and it will test well, garnering good press. And maybe, just maybe, Sigma will put out a 28mm (f2 or 2.8) with the SA and rendering emphasis of the 45mm. Just a thought. A 28/45mm duo with similar rendering pairs well.
I could see Sigma putting out a slightly longer rendering based tele as well, given they now have the highly corrected 65mm, 85 1.4 DG DN and 105 macro at this point.
I think this is the kind of lens they wanted to make with the 45; their own story on their Sein page basically goes like this: management gave them size limits. The engineers tried to squeeze slow but art like quality into the aperture and size limits laid down by marketing. They couldn't manage, in part because no room for floating elements. But some people looked at the results and said "hey, all that SA looks kinda cool" so they went with it.
Freed from the limitations of making the "pancake" of the series, they revert to what they usually do. Which is pretty damn good - as a complete package I think I might prefer this to a 45 style lens at 35mm. But I totally understand someone who wanted something more like a faster 45 (but I'm guessing the quality in other respects at 35 would be much worse at f2.0 if it had a design like the 45 but faster; the 45s design worked partly because it was a bit slower)
I did not know that, very interesting, makes total sense and hopefully many more size limit are imposed!
