|Designed specifically for use with Canon equipment, this versatile wireless flash trigger can control up to three groups of flash guns or studio lights, each group comprising one or more flash guns.
The output levels are easily adjusted for each flash group via the power dial on the Viper transmitter, and are clearly indicated on the LCD screen next to the dial. You can use the LCD display on the transmitter to turn flashgun groups on and off, adjust the flash gun output of each group or set a group to Manual to allow the flashgun’s output setting to override the Viper.
The Hähnel Viper also features a pass-through flash hotshoe, which allows full TTL control of a local flash as if it were mounted directly on the camera. The Viper comes with one transmitter and receiver; additional receivers are available separately (see right) for the control of second and third flash groups via the one Viper transmitter.
