Except, perhaps, you have one motor instead of one in each and every
lens? Seems more sensible to me... And if you update the motor, you'll
see an improvement for *all* lenses.
If you have an original EOS lens, and buy a new lens, you have just
updated your AF technology.
Not really. You are still stuck with the same in-camera sensor system,
aren't you?
Sure, but you have quite likely updated some of the control circuitry and
are taking advantage of improvements in AF motor technology. If you have
in
camera AF, you are locked out of this.
Ehm, people update their camera's more often than their lenses, don't
they? In that case you'd better put everything in-body: Buy a new cam, and
all your lenses have updated AF...
The most important factor is how efficienty the overall system works.
Lens driven AF is more efficient than body driven AF.
I very much doubt that this holds as a general claim.
Two out of four camera companies disagree with you.
Currently. That still does not prove an in-lens system is better in
principle. As a simile, public radio shifted from wireless technology to
wired and back at least two times in the last 100 years...
