Canon WFT-E2A Wireless File Transmitter
The WFT-E2A can transfer images wirelessly through either 802.11 B or G protocols, and has USB and Ethernet connections for situations where wireless access is limited, or impractical. The WFT-E2A is also equipped with a powerful antenna, capable of transmission up to 492' (150 m). The Wireless File Transmitter can connect to a third-party GPS device via the USB connection, providing the ability to attach GPS information directly into the image's EXIF data. Dust-and water-resistance of the WFT-E2A are also matched with that of the EOS-1D/1Ds Mark III bodies.
