Fantastic webcam. Handles just about every lighting condition without any need to faff around with settings. Can handle bright sunlight without blowing out the image, and best low light webcam of the lot. Ive tried loads of other models.
If you want, you can still alter the settings with no less than 3 different Logitech applications, LogiTune, G-Hub and Logitech Camera Settings. They all do pretty much the same thing, though only G-Hub lets you change the image size and frame rate.
Comes with a generous 70" USB cable, and the screen clip is decent too. Im told you can mount it on a tripod too, though I haven't tried that.
It does software selectable 65, 78 and 90 degree field of view, with manual zoom for everything in between, though for regular webcam use, you'll probably set it to 65 degrees, that doesn't make full use of the 4K sensor but its still a very impressive image.
My only criticism is that it doesnt always remember settings between re-boots.
I cant comment on the sound, as I use an external microphone, but I think most webcams are pretty much the same for sound - rubbish!
Ive given it 4/5 for value for money, purely because it's so expensive, and massively inflated at the moment due to Covid home working demand.
