I'll never be able to 'review' a camera with any great usefulness like some on here so I'm not going to try
I just wanted to share a few thoughts about the D7000 I bought a week ago. I know it's been out for over a year now but I have been quite happy with my D90 so only decided to change recently.
It's been a busy week for me and my new camera. So far I have shot the Lakes Classic Car show for Porsche Post magazine and then did the photos for drum'n'bass/dubstep night in a nightclub which will eventually turn up on their website.
So it's been a couple of good outings of contrast, a sunny field full of cars and a dimly lit club. Perhaps I've done a thorough test by accident!
Things I like:
The dynamic range seems to be shockingly good - I struggled a little with the D90 at outdoor car shows where you would expose for the car and quite often the sky would be blown out to white, even on days that weren't particularly bright. I used the D7000 in a good mix of conditions at the Lakes show (dull/overcast, bright but overcast/cloudy, and bight sunshine with little cloud) and in those conditions there was a marked improvement over the D90 for a nicely exposed car and a sky with good colour and detail, so I'm really pleased there.
The Noise. Again, a marked improvement over the D90 which in itself is a decent camera. At 3200 the noise is quite acceptable, and at 1600 barely there. This is important to me as I generally shoot at minimum 1600 when on nightclub duty.
On the D90 I was wary of shooting at over 800, and this just allows me to relax my ISO worries quite a bit.
The new autofocus system. Seems quicker and also seems to nail things better first time, noticeable on panning shots. Also, I use a few lenses that require an in body motor such as a 50mm 1.8, Tokina 11-16 2.8, and a Nikon 80-200 2.8. The autofocus motor feels quite strong and has made focusing on the big 80-200 seem a bit snappier which I like.
Plus all the other little bits:
Twin SD slots that you can set up as you like for backup, overflow, RAW/JPG etc, really good.
Magnesium body and better rubber coating makes it feel a LOT more Pro than the D90.
The viewfinder is 100% coverage so is a little brighter for the eyes than the D90.
So there you go, I'm extremely happy with the purchase and feel it was well worth the £420 it cost me to change from one body to the other.
I was toying with the idea of going full frame to be honest, but I'm not a professional photographer by any stretch and the thought of buying a heap of new full frame glass, especially for the wider end, was just not sensible. Plus I love my 18-200 VR DX lens too much for travel/holidays!
