De gustibus non est disputandum.
I could (and still can) change exposure from wide open to huge DOF
much more quickly with a mechanical ring than a wheel on body*, which
doesn't have any "acceleration" (think in terms of mouse movement).
And that is including the professional bodies like D2H and D1X.
However, there are advantages to both modes of use (better precision
with on-body control, one less hand to use), and I think this
is an useless debate, as it really depends on one's preference... So
sorry for posting a reply to it ;-)
*) for example, with a mechanical aperture ring camera with AE I could
just whack the ring by force from stopped down for outdoors to wide
open indoors or, after some practice, almost exactly wanted number of
stops of difference, very quickly because it offers "direct sensual
feedback" (which the humans are good at) - the amount you turn the
aperture ring. With body control wheel, you have more precise control
but you can't whack the wheel fast enough at times, just because it is
recessed into the grip a lot, and still you don't have the direct
feedback of, even when blinded, turning the ring to the left stop then
turning it few clicks to the right. Which one can do even without
thinking, just by following the sensory feedback. And that's with all
controls, I prefer hard dual-position switches over buttons because
you have feedback even not looking at them. With body control wheel,
you have to look at the display a bit more. But I know one can adapt
to that as well. It's just a preference...
Good light!
