Pretty sensible.

Pretty sensible, but the main difference is that the different marques have a different look and approach to colour. The balance of the mix is different. The ergonomics of the kit is certainly different.
What isn't so different in the lab becomes quite different at the camera/human interface and that's where it becomes a matter of personal taste.

This doesn't really make sense to me I'm afraid. Does it mean that the D7000's images have jagged edges?

Some of you probably want to know how it compares to the competition (Pentax K-5, Sony Alpha 55, Canon 60D). In a word: similar. It's impossible to do apples-to-apples comparisons because there are plenty of things that get in the way of that. But in playing with raw files from each of the cameras with the same converter, what I wrote in the bullets just above tends to be fairly similar across the cameras. The Sony and Canon seem to "lose it" slightly faster than the Nikon and Pentax when you start pushing above ISO 800, but all produce a "usable" ISO 3200 result. The Pentax seems to hold color slightly longer than the Nikon, but it also clearly starts adding noise reduction (even in raw) at the highest ISO values, which means that edges look more anti-aliased. Realistically, if you're nitpicking noise between these four cameras, you're nitpicking. I would guess that if you need ISO 6400 in a DSLR, lenses are going to be a bigger determinant of your final results than the noise levels. That said, I don't like the look of the Pentax files above ISO 6400, or the look of the Sony or Canon files above ISO 3200. The D7000? I don't like the look of its files above ISO 12,800. But if you think about that for a moment, we're talking two stops maximum between all the contenders, and probably less (I doubt those of you reading this are nearly as picky as me). That's the difference between using a kit lens (f/4 on average) and a modestly fast prime (f/2). If you're not already maxing out a fast prime, well, you really shouldn't be pixel peeping noise. And like I just wrote, if you are using a fast prime, the lens you're using is going to determine your final results as much as the sensor's noise.
