I'm starting with the consideration that the goal is to maximize the camera's performance. Only if that's not the case would I agree.
With my 12MP camera, I can often get away with marginal focal length/shutter speed combinations that do not cause blur on a level that can be recorded by the sensor. However, if the resolving power of the sensor is increased, and assuming the lens is up to the job, there is a greater chance for the sensor to record the blurring effect of camera movement. Likewise with a 12MP camera, I can stop the aperture down further before...Show more →
the basis of my argument is about 18,000 shots taken with my D800 over the last 6 months or so. The detail is stunning, certainly at a level the d3 or d4 cant get near to.
ive shot landscapes, weddings, motorsport and birds at all apertures and shutter speeds (here in the uk, we are often at high iso and low shutter speeds) and ive not seen any adverse problems. Landscapes at f18, f20 are as detailed, as sharp and free of diffraction issues as ones at f8 - f11.
Using your hypothesis, a 90 megapixel medium format digital back would be almost useless at all apertures and shutter speeds and we all know this isnt true.
The D800 is the first DSLR that can actually get close, and even surpass some, medium format digital backs in quality and thats a fact that has been proven.
The D4 isnt much better than the D3s, the increased resolution is a non issue and iso might actually be a tad worse.
If you dont agree, then thats fine, i can only go on my own findings.
