I'm very impressed by the image quality, ISO performance and speed.
I don't remember seeing a hands on review here previously, so here's a little summary as I see it.
These shots were done as raw and have had my normal processing, but I think the 100% clips show the ISO performance.
ISO 12800, 150mm 1/250s f/4.5 (Sigma 150mm f/2.8 macro)
At 12k8 this is surprisingly good. I turned to B&W as a red heat lamp washed everything out. The noise is pretty controlled considering. At lot of contrast has been lost.
ISO 4000, 400mm 1/500s f/7.1 (Nikkor AF 80-400mm VR)
I was really surprised at the quality of 4k ISO. Some other areas of the shot show a little noise, but nothing obvious and it is easily hidden by any texture.
ISO 1400, 400mm 1/500s f/6.3 (Nikkor AF 80-400mm VR)
At 1k4 this shows a little patterning in the green background, but I think I prefer this to the same level in my D2Xs.
ISO 100, 150mm 1/400s f/4.5 (Sigma 150mm f/2.8 macro)
The base ISO looks flawless to me. Anything is easily obscured by jpeg compression artefacts.
Things that stand out to me. (keep in mind I'm coming from a D2Xs, so have skipped a generation)
The Good
- Excellent ISO performance (good, because that is why I bought it).
- Auto-focus is very, very good. My slow lenses (80-400VR screwdrive) snapped to focus without any hunting or missed focus.
- The Auto-ISO feature is nice, as it adjusts shutter speed depending on focal length. (Although I mainly used Manual mode and let the ISO adjust)
- 10 FPS is really excessive, but nice.
- I might be crazy, but the images appear sharper. This could be due to the full frame resolution not working the glass as hard, but probably because I can now use the optimal shutter speed and aperture.
- Many more menu options.
- Many more menu options.
- The lcd screen is polarised so that when in normal landscape orientation the screen is completely black. In portrait orientation the screen is crystal clear. This is going to be very annoying with polarised sunnies.
- Battery life does look reduced. I only took a few hundred shots and the first battery bar segment had gone down. The D2Xs wouldn't have moved for those few shots. Still wouldn't be a problem for a single day's shooting (for me).
- I think I expected too much from the 3D focus tracking. I need to play with it more to work out its limits.
