You know, I really enjoy this thread, but not necessarily for the reasons one might expect. Or maybe just a different way of looking at it. I've expressed thoughts along these lines before, but I have been pondering this more lately and figure I might as well post again.
I get the sense there is a competitive element to a lot of the posts here - "look how good *my* camera is*, or perhaps sometimes "look how good my PP software is", or perhaps even "look how good my skills at operating this equipment are". That actually doesn't bother me as such - I'm as much as a show off as much as the next guy. My reservation would be if people who own camera X were getting the idea that because a shot from camera Y looks better than their own shots, that they must upgrade just to keep up with Joneses. There's an obsession with high ISO shooting ability, and as someone who shoots high ISO a lot, I do understand this. But my own obsession has a fortunate outcome - I've long ago come to realize that virtually *all* DSLR's do *well enough* at high ISO that I just don't care about the differences that much. I care ("obsessively" so) that the results are "good enough", but luckily, they are virtually *always* good enough these days.
I see this thread as a celebration of this. We, as 21st century photographers, can relish in the fact that we now all have access to equipment that can make acceptable images in situations our forebears could have only dreamed of. Or at least, would have shot in but obtained results that pale in comparison to what the least of our DSLR's can do. At posted sizes, pretty much every image here looks great - better than any image every taken at the same ISO or even 1 or 2 stops slower a decade ago. Some look better than others if compared at 100%, but I just don't care. As far as I am concerned, the ISO wars are over, and we photographers won.
With that in mind, here's a random illustration. This happens to be the highest ISO picture I've taken lately - the push-processed equivalent of around ISO 4000. Aside from being the highest ISO image I've shot lately, it's not special or unusual in any way, really, but maybe that's remarkable in itself - these days, you can take an image at ISO 4000 with any DSLR and not worry too much about it. This is taken with with the K200D, which is known to be not among the top performers at high ISO, but I can't complain about the results. And as this thread so aptly demonstrates, pretty much anyone can expect results at least as good with any DSLR:
