Out of focus photos when using external flash
7 months ago

I wonder does anyone encounter the same problem as i do. When im using any external flashes like my older sigma flash and now a sony f43 flash with A77, auto focus get very slow and always wrongly focus, even after the focus box is green and after I heard the beep.
No matter what lens am i using. This issue have been bothering me for a few years sing i use A100, A350, A550 and now A77, and therefore, i have changed a few flashes, vivitar, sigma and i thought using sony would slove this problem. But it didn't Have I done sonething wrong?
