Designed for use with the VM-1000S TTL Macro Ring Flash Set for Sony, the VM-1020S TTL Transceiver for VM-1000S from Bolt allows you to trigger the flash, take advantage of TTL auto-exposure, as well as control the power level manually from 1/128 to 1/1 at distances up to 328'.
Working within Sony's TTL flash exposure system, the Transceiver has 16 channels to prohibit interference from other shooters using radio systems. The Transceiver can control and trigger one or multiple VM-1010S Macro Flash units attached to the system's mounting ring, or off-camera using the 2.4 GHz wireless radio operating frequency. Since it has a dedicated hot shoe, you can mount a Sony flash on it and shoot on-camera while controlling off-camera flashes. The Transceiver has 3 groups. Assigning ring flashes to separate groups allows you to light different parts of a large scene or work three individual setups from the camera. The Transceiver supports High-Speed Sync up to 1/8000 sec for controlling bright backgrounds, shooting at wide apertures, or creating an appealing background blur for creative effect. The VM-1020S runs on two easily-sourced AA batteries.
