Obviously the accessory shoe on most FSU`s was meant more for using a finder than a flash since it gets in the way of my forehead and all but prevents easy focussing so I figure a bracket would work better. The problem is the larger (3/8" X ?)than currently used 1/4" X 20" (US)screw size needed. Could someone please tell me how to get around this? Is there an adapter available and or what is the exact size of that camera thread ? Thanks for the help. John
