This Viper TTL Wireless Group Flash Trigger from Hahnel is designed for use with your Micro Four Thirds camera and saves you time and energy on set by allowing you to remotely monitor and adjust the settings of up to three wirelessly linked groups of flashes. In addition, you can use an on-camera speedlight mounted to the hot shoe connector on the top. It is made from lightweight plastic and features rubberized buttons for enhanced ergonomics.

To use the Viper TTL, mount it to your camera's hot shoe using the built-in hot foot connector. Then, use the three buttons on the top to toggle between up to three groups of connected lights and their settings. To test their functionality, press down on the center-located test button on the top. Looking at the rear of the unit, you'll find an LCD display for monitoring and adjusting the settings of each connected group on the fly. A thumb wheel located next to the LCD screen makes it easy to navigate the menu and select items with the button on the right-hand side of the unit.
