I have a Canon 7D Mark II and the Canon EF 100-400mm f/4.5-5.6 L IS II. I also have the canon EF 1.4X extender and I can get autofocus with this combo with the center point plus 4 surround points.
I have my Camera set to beep when I achieve focus.
I am thinking of getting the 2X extender. I know I can’t get Autofocus with this. What I want to know before I buy is if I manually focus would my camera still beep or show the AF confirmation in the viewfinder when the lens is focused on the target?
