Canon's WFT-E4 IIA Wireless File Transmitter (WFT) is designed exclusively for 5D Mark II Digital SLR cameras. The WFT-E4 IIA provides professional photographers a wide range of digital connectivity options including IEEE802.11a/b/g and Ethernet, ideal for commercial and studio work. With 802.11 a/b/g compatibility, photographers can remain wirelessly connected with reliable data transfer rates, strong resistance to electronic interference, and worldwide acceptance in heavy bandwidth environments, particularly within sporting arenas, entertainment venues and retail establishments. The WFT-E4 IIA wireless file transmitter opens the door to new possibilities in remote and geotagged shooting applications. Photographers can fire up to 10 cameras simultaneously from across the room or across the country while maintaining control over camera settings and remote live view on a laptop or smart phone. The WFT-E4 IIA wireless transmitter can also transfer and display images on DLNA (Digital Living Network Alliance) compatible televisions and photo frames. Geotagging is now possible via Bluetooth (requires option adapter), using compatible GPS devices to append coordinate data to the images.
