I see on our Nikon site they say the sensor is a Nikon one and not a Nikon ‘developed’ sensor, just because the sensor was manufactured in a Sony fab might not mean that it is a Sony sensor at all from the ground up, Sony don’t do 14 bit sensors in any case for their own use as far as I know. http://www.nikon.com.au/en_AU/homepage.page
and click on the D800 it shows their description of the sensor on that linked page (which I can’t get a link working for, for some reason).
If I were to second guess the delay with the D400 I’d think about whether Nikon are happy with the Sony APS-C 24MP sensor as is, they might want numerous changes or they might not even want a 24MP sensor, who knows. It sure must cost Canon and Nikon an arm and a leg to keep updating all those high class models they run, all vying for a place in the sun, keep coming up with something that will attract customers, new ones or up graders. I haven’t studied the specs but I think Nikon is slightly over modelled now with respect to the D7000 and the supposed impending at some stage D400. If they upgrade the D400 with the 24MP sensor what do they do with the D7000 when it needs an upgrade, do they go ahead with a cheaper 24MP camera than the D400 and maybe take sales away from it or do they leapfrog it with a slightly higher sensor or maybe go for more MP’s than 24 in the D400 now, or do they decide not to increase MP’s that much and do something like Canon is doing, I’m not sure I’d like the marketing managers job trying to decide that one.
Anyway either way it’s probably a safe bet the release of the D400 was seriously screwed up by the tsunami in Japan and the floods in Thailand.
I’m not sure what Pentax can do to stabilize their product line and make it more ‘normal’ not having a FF camera is probably a big mistake these days when the main opposition all have them, with the exception of Sony of course, they don’t have one in the range at the moment either. But with Pentax they have made only modernized ‘DT’ lenses for their APS-C camera range so to turn out a FF camera would require quite a large expenditure on not just the camera but they might have to upgrade a lot of the old FF lenses to bring them into the digital age as well, a task that might be beyond Pentax now I think, they must have spent a packet on the 645D and releasing a FF high MP camera that’s something like the D800 would only take sales away from the 645D one would think.
