The Hahnel Combi TF is a versatile 2-in-1 wireless remote shutter release and flash trigger designed specifically for Olympus and Panasonic cameras. Operating on the reliable FSK 2.4GHz frequency -- a worldwide licence-free technology -- it delivers a working range of up to 100 metres without requiring a direct line of sight, so radio signals pass cleanly through walls and windows. As a remote shutter release, the Combi TF gives you full wireless control over shutter release, autofocus, continuous shooting, bulb mode, and a 4-second timer delay -- perfect for wildlife, landscape, or studio work where camera shake or physical distance is a concern. As a remote flash trigger, it works with multiple receivers (sold separately) to fire several portable flash units or studio lights simultaneously, making it an ideal tool for building a wireless studio environment. The transmitter is powered by a CR2032 lithium button battery and the receiver by two AAA batteries. With 16 available channels selectable via a 4-position DIP switch in the battery compartment, interference from other units is easy to avoid. Compact, lightweight, and pocketable, the Combi TF is a practical everyday accessory for photographers who want more flexibility from their Olympus or Panasonic setup.
