Logitech C920 Cannot Focus Near Objects

BAD. All the review sites say it's best. I bought it. It has problem focusing correctly for anything within a forearm length. It can focus correctly if something is really close, like 5cm, but when you bring somethnig close, such as a keyboard, within 50 cm but not as close as 5cm, it tries to auto focus but its final choice is blurry. Lots one star ⭐ reviews have similar complaints. Also, the other model C922x, isn't better.

here's a video made with the Logitech C920 Webcam.

you can see, the video is blurry.

If you search reviews, many sites says the logitech C920 is the best. Either lie, or paid reviews, or reviews churned out by clickbait commercial sites. These days, its hard to find proper review.

by the way, the logitech C922x have the same focus problem.

I've also read reviews of other expensive logitech ones. This one logitech brio webcam for $200. It's crap.

Logitech auto focus does not work well when closer in forearm length. Also, the video becomes fuzzy whenever you move, because it's trying to adjust focus.

The Spedal is manual focus. It's a joy to use, no constant fuzzy problem. You actually do not need to manually adjust the focus. Just adjust it once, and it wors ok. If you are a video professional who actually want manual focus, you need to buy more expensive real cameras, not webcam.
