>>3859233I have that lens, and I do really love it.
It's my main go-to walk-around lens unless I'm in the city, when I use the 17mm instead, for the wider FoV. I'm thinking of getting the 7-14mm f/2.8 next year, approximately, when international travel is a thing again and I can go to pretty cities with cool architecture. MFT doesn't have a native shift lens, unfortunately, so I guess ultra-wide is the only alternative.
Anyway... the lens does have CA, but it does a thing that most mirrorless systems do - in-camera correction. Sony, Nikon, Panasonic, Olympus and I'd expect Canon too all do this. It allows the manufacturers to make lighter, more compact lens designs with the sharpness and quality of expensive professional lenses, but at a fraction of the price. Current Sigma DN lenses are outperforming Zeiss Otus and Milvus lenses, thanks in part to in-camera correction.
But uh...
MFT can have a compact standard prime when it has crop factor giving it that advantage. Pic rel is Olympus' 75mm f/1.8 prime which is wide and bulky.
