I got my box this morning and I'm really surprised by the build quality of the "kit" 18-140mm. It is what I would have expected out of a high end Canon consumer lens or even one of the more modern plastic L lenses, not a lowly kit lens. Hopefully the image quality surprises me just as much!
The D7100 body feels good in my (relatively large) hands, though I'll probably end up with a battery grip anyways for vertical shooting convenience. It feels at least as nice as my 50D was, and about as nice as the 7D, though maybe slightly plastickier. The controls are a bit foreign to me, but that's to be expected.
Color this Canon shooter impressed so far! I won't actually get to try her out until this evening.
