Came in the mail today, and it's a nice looking lens. Feels solid, performs well. I did some initial tests, and while it works fine... I just thought there'd be more? I was expecting to be amazed and wow'd! For $1300 it should knock my socks off! The resolution definitely seems to be higher than my kit 18-55, and it is definitely better in low light (VC is great). But as far as focus speed and overall image rendering, it doesn't actually seem all that drastically different. I haven't pixel peeped yet, though. I don't know if my expectations were just too high, or if this is actually how it is with professional lenses. Has this happened to you? I need to be consoled!
