Exactimundo! The two killers for me is camera/subject motion and focus
imperfections. The problem for me is that focus imperfections are
addressable by closing the lens down. camera/subject motion is
addressably by opening the lens up.
I don't believe that emperical evidence supports the claim that
"...any handheld camera used at an exposure of longer than 1/1000 s
isn't going to resolve mroe than about 6 Mpix in any case, reagardless
of the lens or sensor used." First of all, the generalization is so
great that it fails when considering wide-angle lenses and secondly,
it makes an assumption as to a miminum amount of continous motion that
doesn't take into account the oscillating motion of the photographer's
hands which has a moment of stopped motion twice per cycle. Many years
ago I learned the technique of shooting between heartbeats as I
recognized that my hands moved during the "pulse". More problematic
for me is the nature of my shake--it's rotational--not just lateral.
One thing I have to keep relearning over and over again is my own
positional alteration post focusing. I have this tendency to lean
forward a slight bit after I've got focus.
