I have not and will not shoot test charts or batteries or books for my own mental health, but from shooting some normal things, the focus seems ok.
It is quiet but can sometimes feel a bit slow. Will have to look into that.
Cheers!
I have the same combo. It is not the fastest focusing lens but it does just ok. was shooting in really low light and the focus was hunting quite a lot, but I might have been using outer focusing points which is not the brightest idea with 5D.
I have done very scientific test shooting a ruler from weird angle and it showed me a tiny bit of front focusing, but the real life experience shows that the focus is spot on!
