The Pixel Opas 2-in-1 Transmitter/Receiver allows you to wirelessly trigger your Sony camera, Sony speedlite and/or studio flash unit. The Opas has the ability to divide your speedlites and/or studio flash units into 1, 2 or 3 groups and quickly switch between 4 different combinations. In order to utilize these functions, additional receivers will need to be purchased.
The Opas is equipped with 2 hotshoe connections (one to mount the Opas on your camera and one to mount your speedlite onto your Opas) and a PC Sync-Socket to trigger a studio flash unit. The Opas is equipped with a wake-up function, which wakens the speedlite from stand-by mode when the camera focuses. Further, the Opas has a range of 500 meters and is powered by AA batteries (not included).
