I've done it... Bought this lens to be my companion for the time to come. My first impression is that it is so great... It's very silent. Much more silent than any other lenses I have around here. It's super Wide. And I mean very very super Wide. It gets to be scary... I'll post some Wide Shots when I get them. For now there's only one in the flickr pool at 13mm to show how it is super Wide, but it isn't all that good to post here, so if you want to see it go to flickr.
