Looking forward to controlling your flashes with the RadioPopper Jr2? If you're based in Europe, you might not want to hold your breath.
The RadioPopper Sekonic module fits into a light meter and triggers your flashes while taking exposure readings.
The latest RadioPopper's PX-series flash triggers add Canon 1D X and Nissin Di866 Mk II compatibility.
The RadioPopper JrX flash trigger system, which allows remote power control of Nikon and Canon speedlights, is going to be available in Europe as of this month.
