I took this photo last evening and I'm puzzled why it's so overexposed. I actually took 8 photos of this with different apertures and they all look like this. This was in a low light shaded area, so I cranked up the ISO to 2500. I was using my 300mm f4 lens. Camera settings were A priority, matrix metering, f6.3, 1/320, -.3 EV, Landscape picture mode, WB for direct sunlight, captured in RAW 14-bit. I did change the WB in CNX2 from 5200k to about 6000k (can't remember exactly) and reduced the exposure about -.9, and boosted the color. The more colorful photo is the result. Could the WB setting cause this or did the camera just not meter the scene properly? BTW this is not the first time I have experienced this with this new camera.
I only kept 2 photos and the EXIF data shows one at f6.3, 1/320, the other at f10, 1/160. Does the camera record what it thinks the exposure should have been or what it actually did. In other words, if the blades did stick open, would the camera detect the possibly larger aperture and record it in the EXIF data or only record what it thought the exposure should be. Interesting thought, I'll check the lens.
Mine seems to be more aggressive at exposing primary subjects a bit brighter than my D200 did. Never at the expense of clipping the subject, but a featureless sky or background window will be sacrificed more readily if the rest of the frame is in low light.
I need to validate I have matrix metering set vs. center/spot on those shots, but believe I do. Will watch more closely for these situations and the camera's response.
For what it is worth my D70 (no I did not forget the zeros) had trouble exposing a similarly colored rose under what I would call the same conditions based on the info you provided. I took the shots about a month ago and got the same result on 8 of 10, 2 of the shots were exposed better. I believe that this has happened quite often when photographing red flowers. I wonder if it has something to do with the color. It also tends to make the reds more blue. If I was home I would post my results for you to compare. I thought, at first, that maybe something was beginning to fail in my camera but have since not seen any problems.

Looks rather like the result of spot metering off the bloom. If you really did matrix meter it, that's a bad result.
Editing to add: Len Shepherd linked this review which suggests some metering funnies in matrix mode. Perhaps there will be a firmware update in the not-so-distant future if a few more people report similar problems.
Just got my D7000 two days ago and I haven't had much time to play with it, but subjectively I have already noticed a tendency towards overexposure, and have -.7 exposure dialed in. I'm still working through the manual though.
