Hello experts,
it seems that the Nikon D70 / D70s remain the only DSLRs with a flash sync time as short as 1/500s. Even considerable higher priced professional DSLRs don't measure up, not even in Nikon's own lineup.
Is there any technical reason that prohibits the use of such a fast shutter in other cameras?
This sync shutter speed translates into considerably higher flash reach under bright ambient light conditions in fill photography. For instance, under a given condition, the faster sync speed gives a flash on the D70 nearly 60% higher reach than a flash of the same guide number on an EOS 350D (which has "only" 1/200s as shortest sync time).
Very curious to hear your expert opinion. Or does anyone really KNOW why this is so?
