Two new D800 reviews (PB/AP)
In general, when I'm researching a camera, I usually go to PhotographyBlog as their samples are usually helpful because they tend to shoot the same subjects, i.e. London Bridge, which makes it easy to compare IQ across cameras.
As far as D800 ease of use, one thing that impresses me about it is the grip, heft, and feel in hand. It's really doesn't seem much heavier than my D7000 was, and feels lighter, less chunky than my 5D II. The menus are superb. The EV comp button adjacent to the shutter and the angled placement of the shutter button make it a really nice camera to shoot with. Off to check out the reviews you linked to. Thanks.
