that's what i think is so interesting, focus seems to have a fundamental 
importance whereas exposure is so elastic.

or is it ?

the nikon manual for the f5 descibes the "lithium niobate oscillator-controlled
speeds from 1/8000 to 30 sec (in 1/3 steps)...."....

if they can accurately control the shutter between 1/8000 and 1/6666 then we can
safely assume they are getting at least half 1/1333 (or 1/2666) degree of accuracy
in their shutter speeds ?
