Canon WFT-E2 IIA Wireless File Transmitter (1D Mark IV)

Compatible with the EOS-1D Mark IV, plus the EOS-1D Mark III (via firmware upgrade) and the EOS-1Ds Mark III (also via firmware upgrade), the compact, new Canon WFT-E2 II A increases the functionality of your EOS camera. It connects easily and works with WPS setups, and it has Canon's amazing Camera Linking Function and WFT Server Remote Live View shooting. Built-in USB Host compatibility allows for connection to external hard drives, and select GPS units either by USB cable or optional Bluetooth dongle. Designed to mount directly to the side of a compatible EOS camera, it maintains all-weather-resistant seals and the rugged durability of the camera while allowing access to all the camera's buttons and controls.
