Canon WFT-E4IID Wireless File Transmitter

Canon WFT-E4IID Wireless File Transmitter

The WFT-E4 II, designed for the award-winning EOS 5D Mark II, allows photographers to transfer image files securely to a computer or server, control the camera remotely and connect to WiFi enabled devices to view images directly from the camera.

Transfer images securely
Transferring images from the camera to a PC, external hard drive or FTP server is made simpler and more secure.  The WFT-E4 II supports high security WPA2-PSK authentication and AES encryption over wireless networks.  IPsec encryption is also used as standard in both wired and wireless networks to ensure that every photographer’s personal IP is protected.

Remote control shooting
The WFT-E4 II allows photographers to communicate with their camera remotely using a number of different methods. Using the included EOS Utility software, photographers can easily browse and control a wide range of settings on the camera body over a network connection. The EOS Utility allows photographers to control EOS cameras and capture images remotely. This is a major benefit for studio photographers who need to fine tune manual settings and shoot images for instant review on a large screen or sports photographers who may use more complex, multi-camera installations to get the shots they need.

The WFT Server takes full advantage of Java-enabled internet browsers, providing more opportunities for photographers to change camera settings like ISO, focus, aperture and shutter speed, from a computer or portable wireless device such as a PDA or smartphone.  This allows photographers to control their cameras whilst on the move or when in remote areas where carrying a computer may be impractical. One camera can be accessed from up to three different computers or mobile devices, allowing photographers convenient and flexible remote control over their photography.

These new wireless file transmitters take remote capture one step further for professional photographers who want to take exciting pictures more efficiently.  Through the linked shooting function, up to ten slave cameras can be wirelessly connected to a master unit up to 100m away.  The master camera will then trigger the slaves, allowing specialists like wildlife and sports photographers to capture a subject from a multitude of different angles.

The WFT-E4 II offers WiFi Protected Set-up (WPS) - or alternatively an easy-to-follow wizard - taking photographers through a simple step-by-step process to connect the camera to any available network in range.  The WFT-E4 II complies with 802.11b and g standards, as well as the more stable 802.11a wireless standard used at many large sporting events like the Olympic Games.  They also feature an integrated Ethernet LAN port for high-speed wired connectivity.

A USB port and host function also allows photographers to connect several accessories including a Bluetooth dongle for wireless connectivity to GPS, enabling them to geo-tag images for future reference.  Other connectivity options include connection directly to a compatible USB compliant GPS device or an external hard disk drive for additional image storage, improving the workflow for many photographers.
