I have a 5d mark II and the 24-70I , given that the new 24-70II is so awesome and will be out soon would i be better off buying the updates lens instead? I really don't live at high iso settings, landscapes don't tend to run move around, and the center point is golden on my "antique" 5d mark II autofocus system. I am very happy with the color i get up to 1600, but i mostly shoot 100-800. I have a 1d mark III also, so with all that being said would a new 5d mark III really be better than a lens that can actually resolve 21 megapixels?
