I have been trying to use my full spectrum Canon 7D mkII with SGP.
One of the problems I encountered was taking flats in the AV mode. It does not seem SGP recognizes the AV mode.
The other problem is trying to use the camera when the mirror is in the locked up position. Again, SGP does not seem to allow that function.
Are the two above true, or is it possible I am just doing something incorrectly?
