Mine just showed up today. I took a few pictures with it at lunch. I am VERY impressed. I will be using this lens a lot. I'll try and take something that's actually worth posting this weekend. It's extremely well built, focuses as fast if not a little faster than the 18, the MF implementation is actually usable. From the 5 test shots I took optically it may be the best wide angle I've ever used. It's expensive but not overpriced based on it's performance. You just can't compare a $500 or $600 wide angle zoom to it. It's a very high quality lens. Good job Fuji. It's really good at F2.8 from what I've seen, which admittedly was 3 shots at F2.8.
