I love the Radiopopper JrX trigger. I love it even more now because it can be use with my new Sony NEX-5R. That’s right. You can do Off Camera Flash with a point and shoot. how cool is that?!?! Of course since the Sony NEX-5R doesn’t have a built-in hotshoe on camera, I had to get an adapter, MSA-10 NEX, from ebay which cost less then $25. Since I have the RPCube attached to my Canon 600EX-RT flash. I am still able to control the power level via Radiopopper JrX transmitter. Totally worth it.
