Yeah - I was tempted to get either the 20 F1.8 or the 24 F1.8, but looking at the reviews on lenstip, photozone, and a few lens sample reference sites that I use, both are really quite terrible on the corners (basically they are a wider version of the 30 F1.4). I'll still mull on the 28 F1.8.. but I don't know if I really want to get it anymore...
But Sigma Outlet says that it is 20mm F1.8 EX DG ASP RF, which is like the first link, but the picture is like the second link, which was why I was confused by it.
I want to get the 28mm too, but I already have a 35mm and 15mm for something wide. Thinking of getting something in between and 24mm looks just nice in between. But the reviews...
