The Canon WFT-E5 Wireless File Transmitter has been launched alongside the Canon EOS 7D to offer the ability to wirelessly transmit images from your camera to a computer, and give enhanced remote capture, media server functionality and linked shooting.
There are several wireless standards for data transmission over wireless networks, by incorporating the 802.11a standard, Canon have ensured that the WFT-E5 is compatible with a wide range of standards. The 802.11a network operates on a frequency of 5GHz which is an un-crowded band and is less affected by radio wave interference making transfer rates more stable. By contrast, 802.11b and 802.11g networks can be affected by interference from Bluetooth devices, cordless telephones, microwave ovens and other devices operating in the 2.4GHz band which can make transfer rates unstable.
Many consumer electronics devices are compatible with the Digital Living Network Alliance. These include items such as many of the latest generation game consoles as well as some recent televisions and digital photo frames. After establishing a connection between the DLNA device and the WFT-E5, JPEG images stored on the camera can be viewed on the remote device.
Encapsulating the aim of the EOS 7D to be used by photographers looking to experiment with new techniques and aspects of photography, Linked shooting allows a master camera to trigger up to 10 remote cameras over a range of up to 100m. This allows you to capture still images of a subject from multiple angles or to trigger remote cameras to take images from several locations at once.
