I've recently seen a few posts where people have been using their D200 at a ISO higher than what I was comfortable using, and seeing minimal noise. I've been lusting over a D300, but I think I will hold off at least until the spring time. This past week I thought I'd have a go at shooting at ISO 1600. As others have said, it is really all about nailing the exposure. If you get the shot correct (rather than fixing in pp) you will have less noise to deal with. This shot was taken at a Red Sox game earlier this week. ISO 1600, shutter speed 1/1000, 300mm at 2.8. I metered off of the grass. Very minimal pp done. I used the trial version of neat image to reduce some noise. The trial version only works on images smaller than 1024x1024, so the image isn't that large. I do think I will purchase neat image, as it seems to work quite well. Here is the original with slight cropping and minimal pp: And after using neat image: Looking at the two images it does look like the skin tones have changed a bit and a little detail has been lost. However, I haven't really done any pp to address these issues. I think that the D200 is quite good as long as the exposure is correct. I've underexposed quite a few shots at Fenway just because I didn't want to go over ISO 800 or 1000, and, as a result, got lots of noise. Please post ISO 1600 and above images with the D200 to show that it ain't antiquated yet!
