Jr2 Compatibility
Jr2 Transmitter
The Jr2 Transmitter is compatible with any camera body with a standard hotshoe. It is also compatible with older Sony camera bodies using the FA-HS1AM Hotshoe Adapter. It may be alternately triggered using a PC Sync cord between the 1/8″ trigger jack on the Jr2 Transmitter and your camera body.
The Jr2 Transmitter can remote trigger a camera body with the appropriate remote shutter release cable. Please contact RadioPopper Support to determine the appropriate cable.
The Jr2 Transmitter will trigger the following RadioPopper devices: RP Nano Receiver, PX Receiver (when used on Canon compatible speedlights), JrX Receiver (Note, the group used for controlling JrX Receivers must be changed from EV mode to % mode. You will not have stop accurate control of legacy JrX Receivers, though you will be able to approximate power level control from the % scale which approximates the dial position of legacy JrX Transmitter units).
Jr2 Receiver
The Jr2 Receiver is compatible with most all studio strobes and handheld flashes with appropriate sync cable. Jr2 Receivers are shipped with 3.5mm cable, 2.5mm and 1/4 inch sync adapters.
The Jr2 Receiver can remotely control power levels of most E-TTL Canon or I-TTL Nikon compatible flashes, including the Nikon 700 and 900 series flashes.

RadioPopper helps make lighting a quick and natural extension of our creative process and frees us to focus on our clients instead of our gear. They've become an essential part of our shooting style and we can't imagine doing what we do without them

I've always been an off-camera flash user. For a long time I relied on the systems built in IR system. Line-of-sight has always limited my creativity when it comes to light placement. Now I have full control without having to reach for my lights to manipulate settings.
