Hopefully my personal experience with both of these systems can add another perspective for those considering remote triggers for their Nikon or Canon flash units. Not only are both systems described in terms of their individual operational characteristics, but the characteristics of using both systems simultaneously is also described. This article is prefaced by noting that
these are nothing more than my opinions. There are certainly users out there that would not agree with some (or all) of my opinions and conclusions.
The JrX Studio System
At some point it became apparent that the infra-red (IR) trigger line-of-sight system for Nikon flash remote control was not working for all of my needs. The IR system reliability was just too low in some situations, particularly outdoors. Plus, I wanted the ability to put the remote flashes behind barriers.
