Sorry, my laptop browser was somehow on a slightly zoomed in setting which I hardly ever change, so that was why it was looking less sharp. Guess I was tired late last night and didn't think about that. Thanks CPUteq for suggesting that in my other thread.
@MWP, I need to look at my comparison shots closely again and will post them, but the Contax N was sharper in the center with better contrast,less haze and also slightly better in the corners at f8 at 200mm than the 70-200/2.8L. After seeing the differences in highlight detail between my 70-200/2.8L and C/Y 100/2 Planar shots of Denali, I was on a mission to find a Zeiss zoom in that range which I could take on travel instead of the Canon which is heavy and larger. The Leica 180/2.8 APO is very sharp across the frame into the corners and is one of the best lenses I own, it is amazing. But sometimes you need a zoom for those times whether on a boat tour off the coast or on a bus in Denali and can not foot zoom and where you really need the zoom. Plus having the ability for AF or nice focus ring feel MF if you want is very nice. This Contax N is very sharp in the middle and across most of the frame, just losing a little in the corners. So far I am pleasantly surprised by how good this lens is.
