PX Transmitter Nikon Hot Shoe Pop-Up Flash Adaptor

The PX Transmitter Nikon Pop-Up Flash Adaptor allows the PX Transmitter to be attached to a Nikon hot shoe to pick up the pop-up flash iTTL command signal. Note that the PX Transmitter will only work with Nikon pop-up flashes with the ability to send iTTl command signals to remote Nikon flash units.
