James,
don't get me wrong, the D2h is a very capable camera, I have made very brillant protraits-excellent results and I will be posting them in my site soon. But the fact is the d2h is not ideal for me. Lack of experience perhaps.
See the image below, that was d2h on high ISO (not layered or doctored, flash or tripod not allowed) convereted in NC4. I always shoot in RAW if not for anything, because I have in abundance memory cards, and even if I bracket my shots, usually it does not exceed 3, so storage is not a problem. You dare not try shooting low ISO under low lighting because the result is a near black frame and no matter how you twick it in photoshop the result is not outstanding- low latitude of the sensor I suspect.
About the black frames, I'm also not alone on this, and it does not have to be used for 8fps. My d2h, has an eratic behaviour when used in combination with SB800. Eractic, in that sometimes you obtain excellent results and sometimes not- black frames and gross underexposure (I'm not a fan of photoshop but may become in future). If you say that my specimen is faulty, then there are so many of us in that category.
For nature photography, d2h mutes the colour of the sky, the deafult setting over saturates images to something else other than reality. The shot may be okay for some but not for me, I would like to see my blue as blue.
Believe me or not, I think I now know how to use an slr (digital or analogue) correctly, and it is reasonable to expect that a pro level gear should perform much better than what is on offer for the prize.
