We reported last week that the EOS 7D Mark II would see a wifi adaptor that would be a lot cheaper than the WFT-E7A, and it appears that adaptor will be the W-E1.
Specifications for the W-E1
- Size: 24.0Mm x 32.0Mm x 2.1Mm
- Weight: about 2g
- Transmission scheme: IEEE 802.11B / G / N
- Transfer range: 10m/33ft
- Allows the camera to be remote controlled from a smartphone
- Wireless remote operation possible using EOS Utility
