You can add Wi-Fi to your previously unconnected 7D Mark II, 5DS, or 5DS R with the SD card-shaped W-E1 Wi-Fi Adapter from Canon. Sliding right into your camera's SD card slot, this device brings high-speed 802.11b/g/n Wi-Fi on a 2.4 GHz band with a range of up to 32.8'. This enables users to wirelessly transfer their photos and MP4-format video to a smart device, as well as remotely control and trigger the camera, using one of two programs: the Camera Connect mobile app on your tablet or phone, or the EOS utility software on your computer. Additionally, the CS100 Connect Station is supported for wireless backup.
