Wi-Fi is becoming a more common feature on new DSLR cameras, with seven out of thirteen EOS cameras launched since 2012 featuring Wi-Fi connectivity. This new small accessory‚ the W-E1 adapter‚ extends that to ten cameras, bringing Wi-Fi to the EOS 7D Mark II, 5DS and 5DS R.
It's a simple solution that Canon has developed‚ the W-E1 is a small SD card-sized adapter which fits into the SD slot. The W-E1 is not an SD card in itself, and as such has no storage. What it does allow for however is two-way wireless communication with the camera. The adapter enables wireless image transfer (JPEG) and movie files (MP4) from the camera to your smart device or computer as well as remote control of the camera via Canon Camera Connect app and EOS Utility. Additionally you will be able to connect wirelessly to the CS100 Connect Station to transfer your images.
It only weighs 2g and, other than the need to use CF cards for your image capture, is no compromise for your photography.
You can use an existing Wi-Fi network, whether at home or in the studio, or create direct ad-hoc connections with smart devices running Canon Camera Connect app or your PC/Mac with EOS Utility installed. This device uses high-speed 802.11b/g/n Wi-Fi on a 2.4 GHz band and works up to a range of 10 metres (32.8 feet).
Firmware updates are required to make the W-E1 work with the EOS 7D Mark II (firmware v1.1.0) and EOS 5DS / 5DS R (firmware version TBA), which can be downloaded free of charge from the Canon support website:
