Oh, the "lovely" jaggies. Too bad the Ltd. lenses cannot avoid showing them. My Sigma 28/1.8 EX doesn't have them. Sadly, my Sigma 70/2.8 shows them a little bit as well. Maybe it depends on the widest aperture diameter whether they can be avoided or not?
Alan, could you please (perhaps in another thread you could link to from here) explain what "rearranging" of the blades means? How can one actually influence the overall shape? By exchanging blades for another? I'd be grateful to you if you could share your knowledge with us.
