All this talk about the Nikon D800E approaching medium format territory and I think many of us (myself included) have forgotten one of the big selling points for medium format systems such as Hasselblad/Fujinon (Fujiblad) and Phase One/Mamiya (Phamiya), namely that these cameras employ leaf shutters on their better lenses thus allowing flash sync speeds of 1/800th and 1/1600th of a second.
In layman's terms that's more than 2-3 stops what a Nikon/Canon will sync (in reality, not the listed 1/250th white paper specs).
Which means you're able to turn down that sunny-16 (f/16) sunlight down to f/8 or f/5.6.
How do leaf shutters work?
