Thank you, Frank! You see, I've posted this (about 6 months ago) image as a clearly technical one, to demonstrate sheer resolving power of this lens, from corner-to-corner, as well as absence of flare, glare, any CA (to its minimum), or any significant distortions, as well to its minimum. And all of these things, coming immediately from wide open! That's why I am really surprised, there's not even one comment on the lens itself! The image with 2 crops above posted today, to demonstrate beautiful contrast/color ratio, as well as its amazing rendering! THX! LZ
