Reilly Diefenbach: A nice camera, I'm sure, but for an extra $200 you're not going for the D800?
Nikon makes some nice glass but don't be fooled in thinking that you can get their good stuff cheaply. The pro quality lenses from Nikon will quickly put you in the poor house. Their lesser priced lenses are also lesser quality. And yes, I am a Nikon owner owner as well as a Sony owner.
One of the best reasons for owning one of the Alphas is the Carl Zeiss/Sony lenses. These things are razor sharp and produce amazing images. Price wise, Sony is pretty comparable with Nikon. For example, Sony's 24-70mm f/2.8 Zeiss lens costs about $12 more than Nikon's 24-70mm. I own both and can tell you that the Zeiss is worth the extra few dollars.
And for the record, Zeiss makes lenses for Nikon and Canon mounts as well.
