Happy to oblige,

One last thing, I promiss. Here is a link to the 1Ds III review by Juza http://www.juzaphoto.com/article.php?l=en&article=92.

At the end of the review there are a couple of sample images taken with the 1Ds III and the first one with the stuffed moose is taken with the 24-105mm at it's best, it's has trully remakable dietail. Here is the link for the full size image http://www.juzaphoto.com/shared_file...1ds3_iso50.jpg.

This gives you an idea of what a ISO 112233 chart compares to a reall world post proccessed image, there is nothing in that image that would make me want a prime if IQ was the only factor for me wanting a prime for landscapes. The dietail is just great. Granted there are weaker spots in this lens's performance but that is not a decideing factor, besides that there is the 24-70mm f/2.8 which is even sharper and the II promises basically prime IQ.
