I have a set of the "Cactus" PT-04 radio triggers. The transmitter has NEVER worked in the hotshoe of my D200 or D300, but it works fine in my old K1000. Whenever I use the trigger I have to use the sync cord from the transmitter to the body. Not that big a deal but it does get a little annoying. Am I missing something here? A camera setting? Is this normal?
