Surprised I don't see any comments about High Speed Sync. The tech behind pulsing the strobe to match the shutter is spot on these days. Most modern flashes have HSS which solves this issue, I don't see the need for a Leaf Shutter when your flashes support HSS.

Well, one problem with HSS used to be that it reduced the effective power/range of the flash gun.

The strobe has spread the energy stored in its capacitors across a series of small flashes instead of one large one.

Has that been solved now for small strobes (flash guns)?

By using a leaf shutter and a real high sync speed an X100 can use a tiny on-axis fill to do the work of a larger pulsing HSS system.

All true points. The x100 is a fixed lens camera though. HSS flashes are fairly cheap these days; I have 3 Flashpoint ones (low cost Chinese), but I usually only need one. Nice thing is the same flash works (TTL & HSS) with Canon, Nikon, Sony, Fuji, Olympus, and Panasonic. Leaf shutters are nice but the added cost is too high :/
