Those who have followed my exploits with using Sony gear to shoot weddings and such may recall that I've wanted to have a wireless method of using Sony flash units in high speed sync mode for shooting scenic shots of people in bright sunlight. Sure, the Sony flashes have an infra-red method for doing this, but it's unreliable if you don't have line of sight and near perfect conditions. I've been using regular RF flash triggers (the Alienbees Cybersyncs) to trigger my flashes remotely, and posted my method for rigging this up long ago. However, regular RF flash triggers don't provide any method of using HSS mode. Fortunately, the folks at Radio Poppers have created a setup that will work, but it requires some fettling and fanagling to attach the units to the Sony flashes and camera. The Radio Poppers are primarily designed for use with Nikon and Canon gear, but I've been communicating with their staff to get the point across that Sony should be next on their list for creating a mounting system. They have heard from many Sony shooters like me, and I'm sure eventually they will pour some development into our platform. The good news is that the P1 and newer PX models will work reliably with Sony gear. Apparently, the Sony method of infra-red digital transmission uses different pulse timings from Nikon or Canon gear, so certain settings must be used to get them to talk to each other and send the right signals. If anyone here is interested in knowing more about my experiences with this, let me know. I'd be happy to share with the group.
