I am a regular user of radio transmitters, for the past six years. I have real doubts the Odin will work with an F5. The reason is that film TTL and digital iTTL (for which the Odin was designed) use radically different systems to determine exposure. I'm about 95% sure it won't do TTL. It might work as a manual trigger, but I have doubts about that. Even if it did, there are far cheaper ways to accomplish that which are just as good.

Simple TTL will still have the camera send an 'off' signal to the flash when proper exposure is met. Doesn't seem that complicated.
