Frank,

Thank you for the simple explanation. That makes it all very clear to me.

I've had trouble with this in a different setting. Trying to use wide apertures for portraits with my B800. I was trying to use an aperture of 1.8 for a portrait with the 800 set at its lowest setting. I needed a speed of 1/640s. When I tried it, you could see the shutter over a portion of the frame. I gradually decreased the shutter speed, but the problem did not disappear until I approached the syc speed. Why is this happening, and won't the same thing happen in a gym setting if Caleb uses a higher shutter speed?
