I also cannot wait to see it applied to other focal lengths.
I might do that eventually, but the difference is bigger with short focal lengths, because these are harder to build. 50mm and above are close to perfection on the D800, when used at reasonable apertures.
There is also a problem with the test itself: it is not adapted to long focal lengths. With telephoto lenses, the atmospheric haze becomes a problem. I don't normally use this test above 100mm (in 35mm format).
I should also say that am not interested in trying every lens of the planet to find the best one for the D800. If I need a higher quality that what the standard Nikon lens can do, I have the Hasselblad. If I need even more than that, I have a panorama head.
Last but not least, I am also not interested to do tests on order, just to please random photographers on the Internet. I won't go and buy the Sigma 35mm or Zeiss 50mm from my own money just to please you, while I have zero interest for these lenses. When I do these lens tests, I do it primarily for myself, to see whether my lens work correctly and to see which one to choose for a particular use. I published the pictures on my flickr account primarily for me as well, because it is a convenient place to access them. Eventually, some people found about the pictures in forums and, just as in this thread, I go nothing but trouble for my work. People started complaining:
-that my test procedure was wrong
-that the comparison was hard to do (I present most pictures as they are shot and not conveniently rotated)
-that I should publish curves and figures instead
-that I should have tested a different lens, the one that they were interested in, etc...
There is nothing for me in exchange, even a thank you note is rare. I don't make money from advertisement and I am not interested in doing that. Whatever exposure I got did not translate into interest for my other pictures, on the contrary. In the beginning, I hoped that other people would feel motivated to do the same tests with lenses I did not own (I would have benefited from that), but even that did not happen.
So, if you are interested in Nikon lenses on the D800, you can check the pictures at:http://www.flickr.com/photos/jerome_munich/collections/72157630303966522/
but do not expect me to make much more effort than that.
