The Cactus Wireless Flash Receiver V4 works with Wireless Flash Trigger unit V4 when the transmitter is activated. Several flash units work together to help fill in shadows and improve the evenness of lighting.
You can use as many flashes as you wish as long as you have enough receivers. Simply attach the hot shoe of the external flash to that of the receiver, or use the flash's connection cable to connect the receiver and the flash.
With Cactus wireless flash trigger, you can place the flash at different angles and distances from the object. This is particularly useful for portrait and product photography. Most importantly, without the need to connect the flash by wire or cable, you can move the flash to anywhere that produces the best lighting to the object you shoot. Flexibility provides you with the best result. The innovative standing design allows major portable flash unit to sit securely on it without a separate light stand.
The receiver, once it picks up the signal emitted from the transmitter when shutter is pressed, will trigger off the external flash unit. Highest responding time is 1/1000s (actual sync speed varies from 1/125s to 1/600s depending on the sync speed limit of the camera system).
