Hello, I am currently using a canon G7X Mk III with gphoto2. I have managed to capture and download photographs using both gphoto2 from the terminal and with C++. I have also managed to change other parameters such as capturetarget and save the photographs to an SD card.
However, I am having problems controlling zoom through gphoto. I read that first I need to change the parameter "viewfinder" to 1, which i can do because the screen goes black when I do it. After that i try to set the "manualfocusdrive" using (for example) "Near 1" or "Far 2" but nothing happens, but it also doesn't give me any error message. Do you have any idea how to fix this and how I could control the zoom with gphoto? Many thanks for the help, Nuno
