I posted about this camera last it was on sale, because we bought it from Woot! a while back -- we just took it, with the included kit lens, on vacation. I haven't bought adapters or other lenses yet.
And, well, wow. Let me echo all the good stuff (and the negative comment about the huge processing time). I have some nice photos - I've snapped some of hummingbirds, so, yeah, you can get up and running fast -- but there's one I'd like to put up from our vacation. We were driving around and suddenly I realized that there were a whole mess of burrowing owls (!!) nearby, right in the city of Dublin, CA. So I whipped out the camera, but we couldn't get close; in the picture the owls are specks in the distance. But you zoom in digitally, and, WHAM, _great_ pictures, you get all kinds of details. So in bright enough outdoor light, the kit lens is good enough that you really are getting your 20 MP worth, which frankly amazes me.
