hey everyone, first of all - great shots all around
next, why is noise an issue at all? I mean, in my digital begginings, first thing I'd look when reviewing a camera was iso and noise. In time, I learned that there's really no point in judging camera's high iso with 1sec exposure at iso1600 in pitch black night...
Then with my experience, I started to look first at contrast, colors, and things like that, then noise. Then, came time to value noise problems in printed photos, not 1:1 pixel peeping on some crappy LCD display, and now - I don't mind noise at all. If image is really that noisy, for example, if I pushed 2 stops more from RAW at iso1600, I simply switch it to B/W and there's good old grain, as it's supposed to be in BW prints, right?
I have k10d, and I just love that rounded noisy jpg look that comes out, I can't get that "grain" while converting from RAW. I guess that noise really is problem only if you get really messy photo in 30x20cm print, details eaten away and everything in red/yellow cast. As far as internet, forums and uploading images go, we all downsize our shots, and you can easily clean those up without any loss. so, for my money - noise is not an issue
