Hola Marcus, I have been checked all the quests with my problem. My problem is with the vibrations with the mirror movement, I thought the problem was the focus, it is not. I try with the viewfinder to avoid raising and lowering the mirror because it produces vibrations. With the "mirror up" camera setting ("capture mode" to "Mirror up"), I do not know how I can lift the mirror + take the picture + wait 1 second to avoid vibrations and lower the mirror. I tried: ("viewfinder", "1") delay (1 sec)...

Hola Marcus, Is it posible take a photo with "gp_camera_capture" without previous focus??, only shoot (with nikon 810). This is because when i shoot, the camera has vibrations. I use manualy the m-mirror up control on the camera (the first press moves the mirror and focus, the second press it shoots), but i don't know how to do the same with libgphoto2. Thanks

sorry, it doesn´t work correctly, first the camera focus with autofocusdrive and after focus again with gp_camera_capture, the problem is what i need change the parameter "af-activation" to "af-on" because camera focus twice

ok, i try with the option autofocus=Off and gp_camera_capture. I need try focus and if focus is ok, then i get the photo with gp_camera_capture but without focus again (shoot without focus). I do that because i try to focus initiality, if fail i change de focus point and try again (in a while), finally if the focus is correct, i try the capture but i dont want focus again because previously i have it. (in a c++ app) (sorry for my english)

then is it possible than i can save de config autofocus to off with (gphoto2 --set-config autofocus=Off) and set autofocusdrive to "1" ocasionally (programmatically)??

change af-activation parameter

fatal problem
