To be fair the megapixel race was relevant up to a point. For me 10MP was the end of the race because at that point you had plenty of resolution to do some serious cropping and still get a good picture.
The ISO race is similar in that people will on occasion shoot insanely high ISO's and when they do so they will appreciate a camera with lower noise.
What these two things have in common, though, is that they are both appreciated as much by people who are making mistakes in their photography as by the true professionals who shoot under exceptional circumstances and need those extreme resolution values. With the megapixel race if *I* had taken the photo with the correct framing in the first place then I would not need to crop. With ISO performance people need to realize that once they hit a certain point they may be overlooking some of their photographic techniques (like the use of flash, aperture and shutter speed). Without going into detailed description of what I mean I'll just say that not ALL sports photos need to be taken at > 1/1000
Of course there ARE exceptions which is why you can get a 50MP PhaseOne Medium format camera and why you can shoot comfortably at ISO 6400 on a D3. But MOST of the complaining about ISO noise can be attributed more to either user error or just simply wanting to "keep up with the Jones".
So for me the "Clean ISO in an APS-C Camera" race ends at ISO 1600 or 3200. Since this is a photography forum with a lot more talk than pictures here are my examples:
This shot was taken with a Canon 1D (under stadium lights) at ISO 3200; F2.8, 1/1000. Granted it was taken with a Canon but the point is it was ONLY at ISO 3200... so people are talking about how great a camera is at ISO 12,800 and I'm not sure why they need it?
This one from the Pentax (same game) is not quite as good (ISO 3200, F2.8, 1/800) but it is not a professional sports camera and it cost less than 1/4 as much as the Canon. Still - I wouldn't mind seeing a slight improvement in the next generation. Maybe they could consider a new 10MP model camera with improved ISO?
A funny thing is that I had to go WAY back to last May to find photos I had taken at ISO 3200.
