While experimenting with using flash outdoors in daylight, I came across this problem... With flash the highest shutter speed I can go is 250, which means that even at ISO100 I will not be able to use my lens wide open or even 2-3 stops down. This is a bummer when I want a shallow DOF.
Is using a ND filter the only way? Is IQ affected usually? What about using 2 x polarizers?
