This Meike RC-9 S (Sony RC-1000) set consists of two transceivers for wirelessly controlling your reportage flash or studio flash head. The transceivers are adjustable on different channels and have a range of about 100 meters. Thanks to the LCD display and LED indication you know exactly what you are doing. You attach one to the hotshoe of your camera and the other to the flash foot of the flash unit. The maximum flash sync speed is 1/320s.
Also for controlling your camera
If desired, it is also possible to control your camera remotely by using one Meike RC-9 transceiver on the hotshoe of your camera and the other one by hand. This works with single, continuous and bulb shooting. Pressing the button halfway activates auto focus and pressing it all the way down takes the shot. Being able to remotely control your camera is ideal, for example, when shooting with a slow shutter speed. This is a type of photography where you do not want to be bothered by camera shake.
