Originally posted by poco Does the receiver work as a remote shutter as well, or is that strictly a sync port on the receiver?
I'm assuming it's strictly a sync port, since it is battery powered and it sends voltage through the cable. AFAIK the remote shutter release port is simply a "dumb" circuit waiting to be completed (hence the batteryless wired remotes). I might be wrong... but I'm not willing to try it out on my camera's remote port.
As a follow up, I got the V4s a few days ago and they work splendidly with my AF360. I replaced the cheapo AAAs they came with immediately and have had 100% trigger actuations in both disconnected tests and actual "triggered off the K20D hotshoe" and firing the flash. Up to 3fps (for about 5 frames, then my flash is pooped for a few seconds) at 1/180.
Not a long-term test by any means, but out of the box they work great (up to 25m or so), pretty well built, smaller than I expected, and rather fun! Well worth the $40 (or $65 in my case with the extra receiver)!
