| Ok, intersting fact, using the direct to flash via the cord atachment on the 540 makes the cord's shoe hot, so if you had the flash direct on camera and had the cord atached to it with a hotshoe or off camera shoe adapter F (hotshoe adapter f has a pttl pin-out on the shoe-mount and a female pttl hot shoe ontop, the off camera shoe has a cold-shoe and 1/4-20 hole on the bottom and a hot-pttl mount on top. When conected to the 540 via the cord, this shoe is active and will alow another flash to fire or a pocketwizard (PW).
Now problem is that the PW will fire on the pre-flash and from what I can tell will not sync with the camera properly, I have not done extensive testing though.
BUT if you put the flash in M or A mode it eliminates the pre-flash and allows you to have everything sync'ing
good luck |
