Discovered to day that my new Tamron tele-converter does not work with my new 7D Mark II. It works fine on both my old 7D and on the 6D. I use it with the 70-300mm L F4-5.6 lens. Hope that a future firmware update allows me to use it. It totally locks up the new Mark II and the only way to unlock it is to pull the battery out of the camera.
