Is anyone noticing any focusing problems with the G6 at maximum zoom and being closer to your subect (4 feet ot there about)? I have noticed that when set to the widest setting it is tack sharp and locks focus pretty easy, even in lower light. But, if I step back from my subject and zoom in, the lens hunts for focus, sometimes locking at an un-focused point and allowing a blurred shot.
What is the minimum focusing distance of the lens at maximum zoom?
