The Canon WFT-E6A Wireless Transmitter is an impressive device that boasts several upgrades over earlier permutations. Designed specifically for use with Canon's EOS-1D X, this transmitter offers wireless-only LAN functionality for ease when transferring data. It also now supports IEEE 802.11n for safe, fast wireless LAN transfers. Additionally, an internal Bluetooth function (Bluetooth v2.1 + EDR) is included for a secure connection to Bluetooth-compatible GPS devices for high-capacity data transfers.
The WFT-E6A also sports wireless time syncing now, which is a great advantage to those shooting events, allowing you to make adjustments to the device without having a direct connection to a computer. And in another upgrade, the WFT-E6A is also lighter and smaller than earlier models. It still features the same dustproof and waterproof capabilities it's older siblings have. In addition, the transmitter is able to link up to 10 cameras for numerous points of view on a single subject - but now with improved linkage to a WFT server by allowing it to start simultaneously when the master camera and slave cameras are manually connected.
