Got my 40D for 1 year now. I'm very happy with it. Here is the deal coming for the end of the year : switching body or new lens ? Since my lens collection is "FF ready", i'd like to switch for the new 5Dmk2 but i'm afraid of one thing : only 3,9fps, instead of 6,5 for 40D. Is that so annoying ? The 40D is so nervous !
I find my 40D AF not so precise (for wide apertures). Will 5Dmk2 AF improve this ?
Another argument is that i'm dreaming of 85L but my 40D is one of the first produced and i'm afraid it'll be suffering about the drainning batteries issues. Hope that this problem won't exist on 5Dmk2.
Last but not least : will i have better sharpness and OOF effect with my lenses on FF ?
