Had a chance to put the FJ 400 to the test with my Canon ST-E3 RT Transmitter at PhotoPlus last Fall. Everything worked as advertised. Being able to use one FJ 400 as a Main Light (more power) and incorporating smaller 600 EX-RT for fill for example is nice to have in your tool box.
For those that have purchased, how has the reliability been in the real world, albeit it Six Months?
