Unfortunately, I cannot answer the questions themselves, but I would be happy to share 3 experiences with you:

- Positive: The C920e I have has a resolution of 1080p, which is gigantic. More than can be expected for a webcam.
- Logitech includes its own software with the camera, called Logitune. Although I am running Windows 64-bit version, all updates, latest laptop, Logitune did not recognise its own camera. According to internet forums, this is not only the case with me. Therefore, there are also numerous solutions discussed in the forums. The one that finally worked for me was really difficult and requires advanced programming skills, i.e. you have to have the confidence to change codes in Windows. I'm really angry at Logitech: it can't be that a NEW camera is not recognised by its OWN software.
- Another problem: The basic setting of the camera is zoomed out quite a bit. It is possible to zoom in on the camera with Logitune, but these settings are not saved! This means that every time I use zoom or teams, my picture is quite small (basic settings). To zoom in, I have to start Logitune and zoom in there, because this is not possible in Teams, for example.

Conclusion: I already had a camera and wanted to upgrade to one with better resolution because of my home office. So I looked on test platforms on the internet to see which one was the best for this purpose, and the C920e kept catching my eye. As I said, the image quality is terrific, but the disadvantages described are really not Logitech standard and I would not buy the camera again in retrospect. I had too much trouble at the beginning and find it simply tedious that you can only zoom in Logitune and that this is not saved.
