Yes, the CP-5700 can not make use of the fastest cards. It own internal
circuitry is the limiting factor, not the card. Though that is an
improvement over what has been reported here in the past. Typical results
where on the order of 20 sec to write one NEF raw file, no matter what
card. IN my case an 8x or a 40xWA Lexar had the same write speed.

Cameras are rarely capable of taking advantage of the fastest cards
available the day they're released. They're almost *never* capable of
taking advantage of even faster cards released later.

Oh, My 20D has no problems with the Extreme III's (in fact they are
all I use in it).

Good cameras can take advantage of the fastest cards...

My Fuji S2 has no problems with the 80x Lexars, either -- but it
doesn't write to them noticeably faster than to the 8x Lexars.

You'll notice that Rob Galbraith's tests, in the very article you
cite, show that the Canon 1Ds writes just over 2 MB/sec to a Lexar 80x
-- and 1.9 MB/sec to a Lexar 40x. Whereas you Canon 20D writes 5.7
MB/sec to the Lexar 80x. So, is the Canon 1Ds not a "good camera"?
Or maybe, possibly, is my original claim that cameras rarely benefit
from cards faster than were in existence when they were deisgned
looking pretty good?

I wouldn't use the ability to store images quickly to separate good
cameras from bad. The Coolpix cameras can hardly be called bad.

Nikon D2x can write at that speed, too - at least with Extreme III
cards.
