Good day
I a Nikon user, sorry.
But I got 5D3 because I need to focus stack panoramas. My scene require to have sharp picture near the camera about 30-50 cm and then as far as possible.
Until now I used servo and trigger made in Arduino but that is a mechanical solution, and I would like something that is built in camera.
