But I find the Highlighting "anti-flare" capabilities pretty useful, as I do shoot against a bright background with the subject in the shadows/at least 2-3 stops lower than the background. So I need to blow the background away. For eg full length windows behind subjects, subjects in the shade. Just came back from a nice trip with the 24/1.4, really nice effect in the sun playing with f1.4-f2 ISO 100 and 1/4000-1/8000. The thing just does not flare much, so the microdetails and microcontrast on the subject is retained.
With a normal lens you can get back the macrodetails with photoshop levelling, but you are just left with a somewhat blown background, a soft glow (ie bloom) around the subj, and the subj is visible but dark and not much details. For this the details are somewhat retained with the details much "harder" and POP more....HARD. With a normal lens the general feeling is like soft focus....not that the latter is bad, but the performance of the 24/1.4 is there.
