It is the camera's extra sensitivity AF module kicking in. The reason you don't experience it with f/4 lenses is that the module is only activated at f/2.8 and brighter.

Good info, I didn't know that. Could be part of the explanation why this lens produces so much ultra sharp images.

But does the high precision vertical sensitive AF that kicks in from f/2.8 and brighter needs extra time to do it's stuff?
