I should have talked to him before I added the 18.5mm to my order.
I went to Best Buy today to see if I'd totally blown it, but came away pretty reassured. I liked the camera much more than I thought I would. Even if iso, PASM, etc are in menus, the shooting adjustments (shutter speed, aperture, exposure compensation, and lock, are all on buttons, dials, and switches near to hand. I suspect it will be pretty easy to shoot with. The LCD representation of the 3200 shot I just took was pretty good, although my own taste is to get rid of the chroma noise and live with the luminance, which one can easily enough do in raw, which I shoot anyway.
So now I'm excited, not just guilty about my purchase! And yes, the focus is fast.
