Originally posted by King_Boru With out a doubt. I just feel that the new CMOS sensor lacks the subtle tonality of its predecessor. My style of work is to produce images that gently represent the actual subject matter. I achieve this through the minimum amount of PS and or Lightroom editing. I feel the D200 CCD sensor is what helps achieve this look (along with my actual photographic skill). But can this be replicated on a newer camera? Will post processing work double if a new camera doesn't produce the out of camera color that I require?
If you're shooting in raw, and it sounds like you are, then I imagine you can make yourself pretty happy REGARDLESS of what system you use.
Raw is exactly that . . . raw data. Most tonality, subtlety, whatever, emerges out of the raw processing. You can make it as garish or as soothing as you wish. It sounds like you already have a Lightroom preset that is doing most of the heavy lifting for you, and provides you with results you like out of your D200.
What you'll probably need to do, if you get a new camera, is spend some time working on a new preset that makes you equally happy. After that, your postprocessing work shouldn't take much more time, on average.
I won't entirely discount the effects of the sensor (CMOS vs. CCD, different manufacturers, etc.) or lenses, but as you have noted yourself, you've seen an awful lot of good pictures. So I don't think a new camera will hurt. Sensors are better in pretty much every way these days, except maybe low-ISO-noise-per-pixel, but that's more than rectified by the higher resolution.
But hey, results speak for themselves. If you are happy with the results you're getting yourself with current equipment, maybe there's no real need to upgrade. And maybe that's why you haven't.
