Last weekend was spent in an open field testing wireless triggers from China. A lot of frustration & hair-pulling as I stumbled back & forth between the camera & the speedlights. Alas, no assistant on hand.
I couldn’t get the flashes to pop at 350 feet, although the advertised range of the transmitter is 500 meters. I’m not sure why anyone would want to shoot a subject not detectable with the eye, but I suppose it couldn’t hurt.
That is…if it worked.
At 25 feet I got an occasional response.
Alas, a lost weekend.
