Bro, pros i know rarely shoot beyond 6400 leh..
The first few posts on this thread just make me scratch my head.
I think it's safe to say that the D3 and D3s are designed for people like me. And I don't care about more megapixels, I don't care that we have video, I don't care that video isn't 1080p.
I do care about useable ISO and the D3s does that. Maybe there's only a stop improvement but it's a stop in the right direction, and it is a D3s rather than a D4.
I also care about price and frankly, it's appalling. It might get better but the US and UK list prices are, as usual, miles apart.
The fact is the D3 and D3s are designed for sports and news photographers primarily. To other professionals that can adapt it as a tool for them, great. If you need resolution you go down the D3x route, and if you are a rich amateur then you go down whatever route you want.
But don't knock a camera for doing what it's designed to do, better. Just because it doesn't have more pixels, 1080p, or make coffee.
Also, there are plenty of photographers that use high ISOs. Especially those in the camera's target group. Theatre photographers, sports photographers, concert photographers.
Just this evening I was shooting at ISO 5000 and needed to go higher. For night games if I had a stop more speed, then I could get away with a 200-400/4.
More useable pixels, rather than more pixels under ideal conditions, is the name of the game at the moment. I knew the compact camera marketing folk are still desperate for pixels but I thought the DSLR group knew better by now.
