Raspberry Pi Cameras

  1. Where did you get the camera module(s)?
    Camera was bought on Arducam webshop.

  2. Model number of the product(s)?
    OwlSight OV64A40

  3. What hardware/platform were you working on?
    Pi 5 with last firmware and updated packages

  4. Instructions you have followed. (link/manual/etc.)
    64MP OwlSight - Arducam Wiki

  5. Problems you were having?
    Camera is correctly detected and is displayed on screen. My issue is the autofocus does not seem to be triggered. I can’t hear any click with any of the instructions lines (eg. libcamera-still -t 0 --autofocus-mode continuous) and the image is out of focus.

The camera has been connected to CAM0 port and frequency set to dtoverlay=ov64a40,cam0,link-frequency=456000000.

I have no issue with the Pi Camera Module 3.

How to fix it ?
