d200 noise at higher iso's (idle speck-ulation)
firstly, I don't personally think noise is the first and last word on the quality of image available from a camera,. the reason it's been elevated to that status by some(?) appears to be because it's easier to quantify than things like ease of use,. for me I'd prefer to see more tests on stuff like dynamic range,. but in the end picking the thing up and playing with it is usually worth 20+ in depth reviews in my book
looking at the images @ https://www.nikonians.org/dcforum/DCForumID202/153.html">"ISO 1600 D200" may give some sense of the noise and as the camera becomes available and more images are posted all speculation will end and we'll know the answer
what's interesting to me is to look at the d50 and how it renders noise at higher iso's - take a look @ http://www.dpreview.com/reviews/nikond50/page17.asp or another review at http://www.bythom.com/D50REVIEW.htm says
"Noise. I've already mentioned this, but the D50 has simply incredible noise tendencies compared to the D70s. At ISO 1600 in JPEG, noise is lurking, but not particularly visible. At ISO 1600 in NEF, noise is visible, but not particularly objectionable (the chroma aspect of the noise is the primary culprit, but this is more subdued than what I see out of my D70s). JPEG shooters shouldn't be afraid to shoot at any ISO value. NEF shooters should be ready to pull out noise reduction software at ISO 1600."
the other clue that the noise issues may be well under control (someone will correct me if wrong I'm sure) is the d2x specifies 1600 as Hi1 and ISO 3200 as Hi2 - from looking through the online pre-reviews it would appear that the d200 has ISO 1600 as ISO 1600 and above that are the 'Hi settings'
well time will tell and no noise with a lot of in-camera smoothing is worse than noise in some cases but I thought I'd post this while we wait for proper reviews / our own d200s to arrive
