Since the lenses are all leaf shutters, you have X-sync from B to 1/500, which gives you a lot of control. Having to remember to move the PC-cord when you change lenses (actually to re-attach it...) is the hard part.

About the only thing I use the flash shoe for on my cameras is to hold a bubble level. It is placed a little too close to the lens axis for more than fill-in - but aren't all camera shoes?
