Hi, it is my first experience with RPi HQ Camera and I am not sure how to set this set for the best results.

First, I have two rings with camera/lenses. Which one is better to use?

Second, how should I set the lens (like focus or zoom) during mounting of lens to camera?

And third, is it something like “recommended setting” of raspivid (or any other program) for the mounting process?

Thank you for any help.
