hmm, let me post my original question here for clarification:


I just got this lens a few days ago, while I was reading the lens manual, I got a question here.
In the manual, it says: "High accuracy cross (+) detection can be used in the center AF frame and horizontal line detection can be used in the frames other than the center AF frame for the following cameras......"
Does this mean that if my camera is not in the list, I will not be able to get cross (+) detection even my camera's center AF point is f/2.8 sensitive?


I am still getting further clarification from him though, as I just re-read my camera's spec and it shows that it should get cross AF point for f/5.6 lens and get extra sensitive at f/2.8 lens.

"AF System/ Points9 AF points (f/5.6 cross type at centre, extra sensitivity at f/2.8)"
