This wireless slave flash trigger unit triggers other flash units when the transmitter is activated. Several flash units work together helps fill in shadows and improve the evenness of lighting.
Three components are included in this trigger unit, a transmitter and a 2X receivers. The transmitter is to be attached on the hot shoe of the camera while the receiver is to be attached to external flash. Each receiver works with one flash. You can use as many flashes as you wish as long as you have enough receivers.
With the 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 transmitter emits radio signal to the receiver when shutter is pressed. The receiver, once picks up the signal, will trigger off the external flash unit. Highest responding time is 1/1000s.
This flash trigger unit has strong anti-interference function and has four channels for you to choose. It is extremely useful if there are several photographers working nearby. Each photographer could choose their own channel to trigger off the external flash unit they are going to use without triggering others’ because of overlapping signals.
This unit can be triggered continuously for 20,000 times. Triggering voltage is only 0.01mAh so it won’t damage the hot shoe of the camera. The energy-saving design allows you to use the unit for a year without having to change the battery inside.
NOTE ON COMPATIBILITY: This trigger set works with almost all flashes available on market except Olympus FL-36 and canon 430EX and 580EX.
While Sigma EF-500 DG Super works well with the receiver, the EF-500 DG ST does not.
