The D800 appears to be targeted mainly at landscape photographers. Looking at the Nikon sample pictures I noticed that all but one were taken at f/8 or larger. I presume that the 36MP sensor is more prone to diffraction blur and therefore less suitable for the small apertures commonly used for landscapes. How does this affect its usefulness for landscapes?
Also, all pictures were taken with the large f/2.8 zoom lenses. Does this mean that lesser lenses should not be used with a 36MP sensor, since flaws such as corner softness, field curvature, CA etc. would become more noticeable?
