Okay lets get real about the focus issue, for me the only time I didn't like focus on the 5D was shooting in very low light using the outer focus squares when I was shooting like at 1.2 or 1.6
I agree, but I supplant that note with a 50mm 1.2. I had enormous difficulty shooting with the 5D/ 50.12 at the evening of a wedding on Saturday. I actually thought something was/had broken, as soon as I put the 50 on a 1D problems were gone.
