There is no disputing that CZ has made superlative lenses for many decades, my Hasselblad C's and CF's are simply amazing glass, but honestly given the price differential between CZ and Nikkor, which can be substantial, is it reallly cost effective to go with CZ over Nikkor for FX/35mm? Even with the introduction of the D800 and its phenomenal resolving power, I am sure the enlargements would have to be substantial to see any significant differences. If you want to get a D800 because it will let you crop to one small part off the image to make up for your lack of optical horsepower or compositional skills, then I think you should probably need to re-visit your competency level as a photographer first before plunking down a lot of money on a new camera. One of my biggest questions when it comes to people jumping on the 36 MP bandwagon is will they ever really enlarge stuff to the extent that you would actually be able to take advantage of that big jump? Megapixels for megapixels sake is way overrated in my opinion. And it leads into the discussion that so many people seem to get completely wrapped around the axel on all the rest of that el-nerdo techie crap; megapixels, noise, high ISO, blah, blah, blah, ad nauseum, that they forget that the camera, regardless of is simplicity or complexity, is in its most basic form, still nothing but a mere recording device. Always has been and always will be. It is what the person holding that recording device does with it that makes the difference between some rank amateur level snapshot that looks like it was taken by your half blind Aunt Bertha with a disposable Kodak she got at Walgreens, or a truly memorable image. Someone with superior photographic skills could take one of those plastic HOLGAS and simply blow the doors off someone with their fancy D4 if they don't have a good understanding of the basic principles of photography. My D700, at a "paltry" 12 MP enlarges quite nicely to 16x20 and even beyond to 24x30 with my best glass, like the 105mm f/1.8 and 85mm f/1.4 AIS's.
