W-E1 Wi-Fi Card for EOS
Wi-Fi Adapter
Use the W-E1 Wi-Fi Card from Canon to add Wi-Fi to your Canon EOS 7D Mark II, 5DS, or 5DS R. This SD card-shaped adapter slides into your camera's SD card slot to bring you high-speed 802.11b/g/n Wi-Fi on a 2.4 GHz band with a range of up to 10 meters. This makes it possible to wirelessly transfer your photos, and in combination with the 7D Mk II, MP4-format video, to your smartphone, tablet or computer. It will also allow you to use Canon's Camera Connect mobile app to remotely control and trigger your camera, and the CS100 Connect Station is supported for wireless backup.
The W-E1 is compatible with the EOS 7D Mark II (stills and MP4 videos), EOS 5DS (stills only) and EOS 5DS R (stills only). Please note that cameras may require a firmware update for full functionality.
