You must have a much better camera than mine. The shaft disappears if I try to use a faster shutter than 1/500. At 1/500 the shaft is still blurred but I can at least get an idea of where it is. Of course outdoors I don't get any light reflected off of the walls or ceiling so that could have some effect.
I'm using a Panasonic PV-GS320...bought it pretty cheap on sale last week. It's nothing too fancy and is working out well.
