My reason for interest in the new PW units is simple: reliability. Scroll through the other radio trigger unit reviews at the major camera store websites, and you will find al kinds of complaints about poor reliability. All brands, even PW, have some complaints, but the PW brand has far, far fewer than most, even some of the expensive European systems.

I also like the combined transmitter and receiver functionality-three units provides Tx, Rx, and a backup, as opposed to buying two transmitters and two receivers. This is simpler and saves money.

And Phottix has been sued by PW for patent infringement. Another Chinese company stealing intellectual property.


Please don't support thieves.

Nikon007: Why does it have to be so big and ugly?

Easy to find AA batteries. Plus, antennas have to be a certain size to work properly-you just cannot say make it 1 inch long and expect good performance-it has to be calculated. If the size is off by as little as 5%, the range will be cut in half, or worse.

shaocaholica: Can someone explain why when first party camera makers started making wireless flashes years ago they didn't just go straight to radio controlled? Was there some tech barrier?

RF spectrum is tightly controlled by the ITU, the worlds oldest international organization, and for good reasons. Radio spectrum is very limited, and everyone wants certain frequencies, because they are easy to deal with, have long range, reasonable antenna size, etc. Spectrum for new services (flash triggers) has to be applied for, justified, and allocated, and the organization only meets once every four years. In addition, making any radio requires independent testing to show no interference with other devices. Company I work for built an entire building-all wood-just for testing. The tests cost around $50,000. By comparison, an optical trigger is a simple device, with minimal testing required.
