MOKOSE USB Webcam with C-Mount 10-50mm Telephoto Zoom Manual Lens 4K@30fps UVC Camera Free Drive Compatible Windows Mac OS X Linux

I purchased this webcam to be used at a church where I wanted to be able to zoom in on the front from about 30' away. This webcam works great for this purpose. The image quality is excellent as is the zoom lense for this price point. It is important to note that this is a fully manual webcam - with adjustable zoom, aperture and focus. Each ring has a set screw on it allowing each setting to be set while adjusting another. Note that zoom and focus may need to be adjusted relatively simultaneously to get the exact frame you want at the exact focus.lense does seem to be more configured for close ups than distance with the focus and zoom. Close up, you can focus very well. Further away, there is some limit of the zoom while focusing but it is still very much useable. Beyond the zoom and focus, the image quality is outstanding both when there is decent lighting (LED light panels or sun) and minimal lighting (ceiling lights only). The camera uses the standard windows driver, which allows for minor adjustments to color temperature, contract, and brightness. I was so happy with this camera I purchased the other two zoom models as well.

Using this for Zooming meditation classes as an alternative to a cheap ($200) camcorder which would need a video capture card. Also it has a much larger sensor, so the picture quality is better than a cheap camcorder.This basically has the perks of good camera with optical zoom and aperture setting, but made for webcam use in a computer. It is completely manual, and because it has no display, you need to be able to see the computer screen every time you adjust focus, zoom or aperture.Unlike many webcams, it is not autofocus, and the focus changes when you change the zoom.Easy to lose the set screws, but they don't seem so important for my use.

This camera worked out of the box with my Windows 11 laptop. The picture is very clear and the video did not stutter at all. I love the quality of the lens. It allows you to zoom in and out, adjust the brightness and focus the image by using 3 different adjustable rings on the lens body. I use this camera with the Zoom application. I would recommend it.

Lens has three adjustments: aperture, focus, zoom. All work fine throughout range.I used the camera at its full zoom setting, mounted on a tripod to view vehicle traffic. Fully met my needs.
