I've been following Zeiss maniac Lloyd Chambers. His comparisons really show how canon/nikon gear just isn't holding up to the level of quality of Zeiss, not to mention Leica.
the MF issue worries me but it seems from this thread that owners don't find it that big a deal since they aren't spraying and praying. I think I'll keep AF glass but will defitinively head to zeiss for my video/landscape needs. their glass is just gorgeous.
