hard to say until we see the optical performace of the new lens I think...
to some the 9 blades (more natural bokeh) and the more silent (and maybe faster) auto-focusing maybe all that they would be happy with to get this lens...
for those who don't have the AF 50mm... they now have two options to go for (of course it may not make decision easier :bsmilie: )
sorry to OT abit why are everyone excited abt the 9/7 blades elements? any difference as in the elements? my understanding is more elements the more complex and more prone to flare?
with 9 blades, you get a nicer bokeh, esp shooting wide open.
it can be quite a significant difference. but again, this is subjective.
some ppl like it some ppl dun.
