Hi guys, just bought a T with 11-23 and 55-135, upgraded to fw 1.43 and I have noticed the when the tele is fitted I have 5 Auto Focus options instead of the standard 3 (M, AFs, AFc): the menu shows also AFs and AFc with a couple of small arrows on the sides, as shown in the pictures. I looked on Manuals, forum, etc, with our finding what do they mean. Any idea?? Many thanks!
