HAHNEL – Viper TTL Wireless Flash Trigger for Sony
The Hahnel Viper TTL Wireless Flash Trigger for Sony provides multi-group wireless flash control to Sony cameras. It operates with a 2.4 GHz frequency with a range of 100m. The system uses Digital Channel Matching to quickly and reliably connect up to three groups of receivers with a transmitter and avoid interference from other devices.
Flash output can be set via the transmitter for each group from 1/1 to 1/128 with intermediate stops of ±0.3 and ±0.7 for more exacting control over your lighting. This is all shown on the transmitter’s backlit LCD. Additionally, a manual mode is available for setting options on the flash itself and there is a pass-through hot shoe on the transmitter for TTL control of a mounted flash.
