I've been using the Logitech C615 web cam for some time now, for timelapse photography. However I'm not perfectly happy with its focus at "infinity". It's not perfectly clear. On closer distances the image is perfectly clear. It just seems that the focusing motor or its focusing steps are tuned for closer distances.
Which is expected and perfectly normal! But I'm wondering if there is a possibility I could open up this camera and modify something to calibrate the focus to be more optimised for distance.
I've found a picture showing the inside of this cam:
I've added these red arrows to point out to these pins which look like they are there to assist in manual turning of the lens. I did not take my camera apart yet because I'm recording a timelapse with it right now, as it is, so I would not like to take it apart if there is nothing I could do.
Here are some pictures from the camera as they are now.
Totally out of focus: 50%: 25%: Maximum:
