Re: Nikon D3X 24.5MP full frame pro DSLR officially unveiled today
The D700 inherited quite a bit of the internals from the D300. I think both the D3 and
D3X have their own raison D'etre.
D3 caters for the sport/action/photojournalism shooters and D3X would be used more by Landscape/nature photographers, Studio camera and situations where the camera is sitting on the Tripod. Same as the case of the Canon 1D / Ds MarkIII
D3X/D3 not having the sensor cleaning mechanism like the D700 did not come as a surprise to me at all. Nikon has done this in the past as well. Example that comes to mind is from the film era.
Take a look below listing advantages of F4 over F90x and vice versa. F4 and F90x for their era were the parallels of the D700 and the D3/D3X.
The primary advantages of an F4 over the F90x
Interchangeable viewfinders (right angle, waist level, reflex prism, etc.)
Conventional (traditional) controls
Slightly higher continuous frame rate (5.7 fps versus 4.3)
100% view in viewfinder
The advantages of the F90x over the F4
Faster and better autofocus mechanism
More sophisticated matrix metering
and yet both F4 and F90 sold well.
The current economic climate will have an effect on the Nikon D3/D3x sales with the later's introductory sales being low. For Nikon D3x to justify the high price, its native image quality (sensor detail resolving power and sharpness) will have to be at par/better than the Canon 1D Mark III
