Ain't that the truth!
I have a 10-20 and even yearn for 8mm now too after Sigma's success story.
Originally posted by Ash SDM, I'm hoping (real hard), is a success with this model and is built as sturdy as the lens itself will be...
True, Otoh; one is left to wonder why aren't they deploying the new AF drive built into the (new) 18-135 in this one too?
I know its early days yet but it seems to be gathering huge acclaim from all directions, plus the 18-135 isn't that expensive unlike most SDM lenses so its inbuilt AF is probably cheaper to make/sell and seems compact enough too.
