The Hahnel Combi TF is a 2-in-1 wireless remote shutter release and flash trigger designed specifically for Panasonic Lumix cameras. Operating on the reliable FSK 2.4 GHz radio frequency, it delivers a working range of up to 100 metres and does not require a direct line of sight - radio signals pass through walls, windows and other obstructions with ease. As a shutter remote it gives you wireless control over autofocus, single and continuous shooting, bulb mode for long exposures, and a 4-second timer delay trigger. As a flash trigger, the transmitter mounts on your camera's hot shoe while the receiver attaches to your portable or studio flash unit, allowing off-camera flash to be fired in sync with the shutter. Multiple receivers can be used simultaneously to trigger several flash units or studio lights at once. Note that the flash must be set to Manual mode - TTL signals are not transmitted. The compact, lightweight design makes the Combi TF equally at home in the studio or out on location.
