Unfortunately, I have not found a discussion of this problem here, so I am writing about it.
I found that when I try to focus on distant objects, for example, at a distance of 30 meters, I encounter the fact that the image of distant objects is blurry. In this case, objects located, for example, at a distance of 5-10 meters, come into focus.
I apologize for attaching a poor quality photo. These are screenshots of the screen recording. When I started recording the screen, I didn’t think about the recording quality.
But even they show that the focus does not fall into the background. And this problem exists on both the periscope module and the main camera module.
This problem is also observed in GCam and BlackMagic Camera.



Please tell me if anyone else has encountered this. I suspect that this is not a software issue, but rather a problem with the optics of the entire module.
