Any user experience comparing the 2? I know one if life size and one is not. The Zeiss bigger aperture attracts me though as I can use it also for nice portraiture.
Will be used on 5Dmk2. I am perfectly ok with AF or MF.
I have both, and I prefer the Zeiss unless there's something that would result in the purple fringing; the Zeiss is much worse for that. Don't shoot anything with shiny metal in the sun with the Zeiss!
