I mentioned in my request that I was asking on behalf of more than just myself and that many of us are chomping at the bit for the offical OK to use their bats with the 540. If you listen very closely, you may actually hear the echoes of, "Yeah...whatever...". -Brendan --- Paul Stenquist <[EMAIL PROTECTED]> wrote: > I bought the external battery pack for the 540 > flash.
