Canon WFT-E4A Wireless File Transmitter (5D Mark II)
The Wireless File Transmitter was designed for use with the EOS 5D Mark II Digital SLR. It is compatible with Wi-Fi Protected Setup connecting easily to a wireless LAN access point to secure image transfer. Sending a batch of photos wirelessly is made simple with the WFT-E4A because images can be stored in selected folders and the entire folder can be then transferred all at once. The WFT-E4A retains the same features as the WFT-E3A including great handling for vertical shooting and wireless transmission (802.11b or g) to both Macintosh or Windows computers for distances as far as 492 ft. (150m). The WFT-E4A is powered by a single LP-E6 lithium-ion rechargeable battery pack.
