800D + 100-400 f5.6 II + Extender 1.4x III AUTOFOCUS WORKS ON F8 27 POINTS

Hi.. Just bought my 100-400 f5.6 II + Extender 1.4x III and the big question was will it autofocus at f8 and at the 27 AF points  on the t7i (800D) like the manual says it does. YES@@@@@@!!!!!!!

And... it is FAST FAST FAST, BRIGHT BRIGHT BRIGHT  and the IS is amazing!!!!  My Tam 18-400 would wobble in the VF at 400 (640 on my crop)..

The new lens combo achieves 960mm (with crop factor)  and is stable stable stable at 1/800...

I haven't tested it yet.. Will do so this afternoon

Yippee!!!!
