I can't help but wonder what folk shot on before the D800?
It's back to the old camera club bore thing:
"What kind of camera do you use?"
"I use a camera X"
"Oh you can't possibly get decent pictures with camera X"
The 1DX looks lovely, but I can guarantee I'm never going to own one, or a D800. My camera works for me, when it breaks or something more useful is released that makes my work easier then I may replace. In descending importance: Being there. With a camera. At the right moment. Knowing how to work the camera.
Megapixels, lens resolutions, card speeds, focus screens are on the list, just quite a bit down it.
I have an 18MP camera, which is about 10 more than I reckon I realistically need. I only sold my 10MP because I wanted video. I would love a very large photosite 8MP APS-C camera with digic4 or digic 5 and video.
The great thing with the D800 and the 1DX is that hopefully the technology will trickle down. I don't want an F1 car for using around town, but if my car has better brakes, or uses less fuel because of f1 technology then I'm happy.
The pro's seemed to have coped and got covers with D1's, D2's, D3's, 1Dmk2's, maybe not 1Dmk3's, 1Dmk4's etc.
