Please forgive my inexperience, but I am having trouble focusing my Arducam 12.3MP IMX477 HQ Camera Module with 6mm CS Lens. I can turn the outside ring marked open and close and change the picture some, but the inside ring marked near and far does not budge. I have unscrewed the the pin some but the inner ring does not move. Could someone tell me what I need to do to focus this?

Hii @texas_pete,
you just lock the open-close screwed and loose the near-far screw and adjust the lens.
Check if there are any updates.
