Got the lens, came in a couple days from the East to the West coasts.
Nice lens! Feels less "pointy" than the 18-55. It's not much but the slightly wider 55 versus 52 and slightly shorter length add up to make it seem more balanced and a better fit to the camera body. Of course that's the retracted size, when "deployed" it's much longer. Otherwise beautifully built like the other two lenses. I love the design of these lenses, totally sleek and minimalistic.
Pictures look great otherwise, as a package much nicer than my 5DmII + 16-35 (this is 18-35mm equivalent I believe). Haven't done extensive comparisons but the IQ of the 5DmII is of course better, but the 16-35 has distortions left and right compared to this one which seems to be pretty flat field across the board.
Combined with the 18-55 this is a killer combination.
