Having trouble with AF in low light with the kit 18-55 IS II when using the flash and the built-in focus assist light. The lens will hunt out and in, and I will get focus confirmation (focus point blinks red), but the picture is out of focus.
Centre focus point manually selected, AI Servo, any aperture that I set. AV Mode, back-button focus.
try using one shot and see if that makes a difference. I never had much luck using AI Servo, but then i don't really shoot action shots either.
