Just received above RFN-4s for D800 and tried it out for a few shots.
I was kind of worried about the protruding antena on the receiver, but it turned out smaller than I expected. The antena is made of FLEXIBLE RUBBER-LIKE material, I don't think it will be in anyone's way to cause any trouble.
Oh, yes, its RF signal works very well, but the transmitter needs 1 AAA battery(supplied).
