I am experiencing very slow autofocus with my Canon 6D whenever I use it with my flash, even in good lighting conditions. The lens I use is the 24-105mm F/4 L IS USM lens (kit lens) and the Canon 600EX-RT flash. I have tried the different modes on the flash but they all have the same effect. What can it be and how can I fix/improve it?

actually it should be fast coz the flash would avoid the low light bottleneck issues nd actually the 6d doesnt require a flash unless during night or extreme noisy conditions...nd btw howz it focussing widout the flash...if its +ve den it would be the lens...take ur lens to a gud service centre
