I'm still getting used to the camera's controls, and I have yet to decide whether I prefer shooting through the viewfinder or the LCD, but one thing is for sure: the thing is a rockstar at low-light. I'm accustomed to cameras like my G10, which barely likes to go above ISO 400, and even on my 7D groans a bit at 3200. But this thing took 3200 and shrugged it off like it was nothing. I even cranked it to 5000, and while it got a little soft, I didn't see the multi-colored confetti-like noise I would have seen on the 7D. As a bonus, it's svelte form-factor makes it comfy to hand-hold even at low shutter speeds like 1/10s.
I won't go on much more - I don't have that much to add to what's already been said about this camera. For my personal shooting style, it's going to be a bit of an adjustment working with the prime 35mm-equivalent lens, but I can already tell I'm really going to like this camera.
All of the following images are straight out of the camera, except for the second one, which was cropped slightly.
