Super shots REX. Your post prompted me to research this lens and it is getting rave reviews. 11" minimum focal distance (less than 5" from the end of the lens!) and sharp corner to corner. At US $1100 I am not sure when/if I will get one. I can dream I suppose.
I may just have to make do with my Minolta 100mm f2.8 D for a while.
We should have a post for the best macro, although I am sure you would win.
