Hi Cory,
While we're still on the power supply
matter can you tell me which is positive
(+) on the AC mains adapter plug? The
outside or the pin. I'm making up a lead
with spades on one end and a concentric
plug on the other to use a 6V 8AH lead
acid gel accumulator when the camera is
on the microscope, or when cleaning the
sensor. I'm guessing it's the pin -- but
I have a small flash here that has
things the other way round.

2.1Amps is way more than enough, I dont know why they would design
theirs for 3A, unless they intend to use the same supply for other
bodies not yet released, i.e. 645D.
... or bodies that can charge batteries.
... or lenses that take a lot of oomph to run the AF.
... or larger LCDs that take more current.
... or memory cards that take more current than mine.
Lots of possibilities... my setup is only representative. Having
more is always better, and a 3A 6.5V switching power supply is
negligibly more difficult/expensive to design/build than a 1.5A 6.5V.
It's still only a 20W power converter... trivial.
