What is the least expensive wireless transceiver available that can activate off camera flashes without having to be mounted in the hotshoe? Otherwise with pass through ability? I have a Canon 40d, btw.
I prefer to have a flash mounted in the hotshoes while activating off camera flashes. It can be manual or e-ttl.
1) I own some Yongnuo rf-602's for shutter release purposes. The 602 transmitter has to be mounted in the hotshoe to activate off-camera flashes though, so this won't work.
2) I owned some Yongnuo rf-603's a while back but only briefly.
I think these might work but I cannot recall if you can use a PC cord attached to the camera and transceiver to activate off-camera flashes; with a flash also mounted in the hotshoe?
I know the Yongnuo yn-622's (manual & ettl) will work as well as Phottix Stato II (manual) but I don't need all the features, especially if I can use the inexpensive rf-603 as desired?
