While I think the 2.5 stars for optical performance is somewhat low, since it is penalized by relying on digital correction, however once corrected the performance is rather acceptable.
OTOH there are Canon 15-85, Nikon and Pentax f16-85 all three suffer much less vignetting and distortions and they had to deal with longer flange distance, so it is feasible, however they seem to have prioritized the small size, and constant aperture.
I do like my Canon 15-85 a lot and it is not that big along with 750D or 7Dmkii it is my usual hiking kit
