S suresh gupta Guest Mar 12, 2012 #1 Mar 12, 2012 #1 1. 5D mark 3. Auto focus works upto what aperture ? That is, with the 100 -400 lens, will it auto focus with 1.4x, and 2x extenders ? 2. In video mode, does it have continuos auto focus, and auto exposure ?

L Loswr Guest Mar 12, 2012 #2 Mar 12, 2012 #2 An f/5.6 or faster max aperture is needed, so no AF with 100-400mm + any Canon TC. No continuous video AF. Upvote 0
