The Canon WFT-E2, WFT-E3 and WFT-E4 Wireless File Transmitters for several cameras in the EOS range allow you to either send files wirelessly or control your camera from the comfort of your computer all without using wires!
Aimed mainly at studio and news photographers, the WFT units can be used to get large previews back on a computer to wire images to a picture desk almost as soon as they’re taken.
The WFT-E4 Wireless File Transmitter.
802.11b and 802.11g
PTP, HTTP and FTP protocols
Up to 150m range
Ethernet 110 Base TX connector
The WFT-E2, WFT-E3 and WFT-E4 units offer multi-protocol control and convenient USB hosting in a compact package. The units allow you to connect to both wireless and wired LAN networks with full support for FTP, HTTP and PTP. A new connection wizard makes setting up a WiFi connection quicker and easier than before and allows WPA-PSK authentication and TKIP encryption to ensure secure data transfer.
For those working in studios or on location these units are the quickest way of getting your images in front of your clients. Shoot tethered using an Ethernet 100Mbps connection for fast image transfer; wirelessly transmit images using 802.11b (11Mbps) or 802.11g (54Mbps) connections; or simply use the USB host functions to shoot images direct to an external USB hard drive.
To retain the weather sealing of the cameras, the units feature a built-in antenna. These units are perfect for commercial studios, sports and wedding photographers. At a wedding you can remain mobile, free from the clutter of cables. Images can be transmitted immediately back to a base-station where an assistant can select and edit them on location and present a slideshow in time for the wedding reception.
For sports and news photographers, images can be transferred directly to the picture desk, using HTTP mode, for review by the picture editor in almost real-time. For the busy commercial studio, having images available to view by the client or art director while the shoot is going on can save time. The art director could potentially give meaningful direction from anywhere in the world. Alternatively, it can be used in less pressured environments to get images onto a larger screen where they can be checked for lighting and focus issues.
If you want to geo-tag your images so they can be located on a map, you will also need one of these units as it provides the connection to allow the latitude and longitude information to be embedded within the EXIF data of each image you take.
