Canon's EOS-1D Mark IV, EOS 5D Mark II and EOS 7D SLR cameras are all now compatible with new Canon wireless file transfer (WFT) systems.

With a WFT system, users are able to fire up to 10 cameras simultaneously with the camera linking function, geo-tag images with GPS devices, and send images to a computer for instant prints or screen projection. Users can also set up an FTP connection on which they can access their images remotely.

Canon WFT-E4 II—made for the 5D Mark—and WFT-E5A—made for the 7D—are currently available, and both sell for $699. The WFT-E2 II A—made for the Mark IV—has yet to be released.
