Now please give me a Nikon version of the 5D and we will be set
Wouldn't the D3 count as one? It's like the 5D on paper, but with a better fps, better screen, and better live view than anything Canon has (in terms of AF and screen quality). D3x early next year should be Nikons "24 MP is too many megapixels for it to go past ISO 3200, but hey.....it's great marketing" camera. I know, long name.
I don't really see the practicality of it. Too many MP crammed onto that sensor. We're likely to see the weakness caused by the number of small photosites. If you want Medium Format, choose medium format. For the money you pay for a Canon 1Ds MkIII, you may as well. You'd get better image quality, too (although not at high ISO.....).
I think the D3 is my dream camera, with the D300 a fantastic 2nd choice. Actually, in some ways, I'd rather have the D300 because it's a APS-C sized sensor, and I'd like to stick with it. However, I must say that I have more worries about the D300's image quality. I don't think the D3 could possibly be bad. After all, it wouldn't be like Nikon to introduce ISO 25600 if it's going to be completely and utterly unusable. If it was unpleasant but still quite usable (ie: not the best, not even "good" without post-processing, but usable if touched up) , then Nikon would include it. However, Nikon would have stopped at ISO 12800 setting if no useful photos came from ISO 25600.
They would still have bragging rights at ISO 12800, so there was no point going beyond that unless it worked.
This is great news. Both camps are coming out with some killer cameras, and should make everyone quite happy. With Nikon switching to CMOS it will finally put to bed the debates over which sensor style is better, and will hopefully also kill the infamous "noise" debate.
It was stupid anyway. They're both equally good at collecting light. It's just Canon's readout technology was better. Sony's CMOS didn't fare as well as Canon's. Why do you think they didn't use CMOS in the Alpha-100? They had at 10 MP version in their R1, but they didn't bother using it in their DSLR? There's a reason. Readout noise and the size of each photosite is most of the problem.
The choice of CCD or CMOS also depends on the output from the sensor, I believe. They both output analogue signals, but after this first step, the processing is slightly different. Maybe the CMOS signal undergoes one less processing step, or a step that's less noisy. I don't know enough specifics to want to discuss it further, though.
