Got up at what seemed like the middle of the night last weekend for the first real test of my 50D (just upgraded from a 30D) & 17-55mm (actually the first one was with the sigma 10-20mm) ... I have to say the quality difference between the 30D & 50D is staggering and I am in love with live view now!
edit: Just noticed these all look softer than the full size versions




#2 is my fave
