All it says is this"
Please set camera dial to "Manual" Error: EDS_ERR_PROPERTIES_MISMATCH
But "Manual" or "Bulb" should be acceptable (with bulb being preferred). If you set the camera to Manual and attempt to connect does it work? If you set it to Bulb and attempt to connect does it work?
We may need to add a check for the 70D to allow it to connect in Bulb if Manual works.
Thanks,
Jared
