2.8-12mm Varifocal Lens 1080P USB Camera with CMOS OV2710 Image Sensor

The camera is good for a 2 mega-pixel. The build quality is good. The case is surprisingly heavy. I am using this as a security camera for the front door.Next one I buy will have a higher power zoom lens and mega-pixels. Also, it doesn't do great in dim lighting. Otherwise, it's a great little camera! Well worth the money if it meets your needs.

This wide-angle to short tele lens model is being used as a PC camera (UVC).The good:Image IQ is decent in good light and sensitivity can be partly controlled with a manual aperture ring. That also affects the depth of field.Varifocal (type of zoom) lens allows for tighter cropping than the typical wide-ultrawide lens on a webcam.Camera works in Windows 10 without any drivers. It is literally plug and play, which is great for good for WFH on corporate computers.Manual focus avoids the camera auto-focusing to and fro. (Some might find this a con.)USB cable is long and thick, so placement is not an issue and it should be durable.The bad:The 1/4-20 sockets are not flush with the body of the lens, so there is very little surface area to contact and they tend to rotate on hard mounts. The two sockets allow for upright or hanging options.The lens quality is mediocre. At the wide end there is hard vignetting in the corners and serious barrel distortion. At the long end there is moderate pincusion. Image is better in the middle third of the zoom range.The lens is varifocal (not anywhere near a parfocal lens that maintains focus while zooming) so the focus must be changed when zoomed in or out. The zoom and focus controls are very small and easy to inadvertently move, so plan to set up the camera at a particular setting and leaving it there for the session.

Ordered the 2.8-12mm version, received the 5-50mm version in a box marked for 2.8-12. Still usable for my needs. Lens is sharper than expected - if you are within the focusing range. Zoomed to the 50mm setting it will not focus very far away 7 or 8 feet is about as far as you can be. That improves rapidly as it is zoomed out. Lens has a 3 blade iris diaphragm that closes into a somewhat arrowhead shape giving a strange bokeh to out of focus highlights. The image is also vignetted quite a bit and at the wide (5mm) setting has significant barrel (fisheye) distortion. The attached images demonstrate. The blurred picture is at the 50mm setting, subject was at 12 ft from camer and could not be focused upon. The other picture is at the 5mm setting and the doors were about 15 ft away.The imaging sensor seems to be of high quality, wish the lens was of better quality.

The 2.8-12mm camera was perfect! Exceeded my needs. There was a slight issue with receiving the wrong view angle camera, but without even a call, support sent out the correct one ASAP and without asking, just to make sure everything was what I ordered. I will be doing more business with them for sure! Thanks!

I wanted a camera with manual zoom and focus that I could adjust, for Zoom calls. I had bough other cameras that have a wide eagle eye angle which can only be adjusted digitally, which lowers the resolution of the image. The camera feels solid and heavy-duty. With this camera I can focus on my face and upper torso, bringing everything else out of view. It has manual zoom, aperture, and focus, all in its zoom ring. The image is clear and high definition. The only problem is that it does not adjust exposure and sensitivity automatically. When I first plugged it in, the image looked very dark. You have to download a free application named Amcap to micro-adjust these settings and others. It is plug and play, but it does not work out of the box. You have to manually adjust all settings manually and with this Amcap program, which can take some time and technical savvy. Once all adjusted, it keeps the adjustments and it works reliably.

I am very disappointed in this camera. I have to wonder if the one I received is defective or the reviews are fake. The overall image quality is good, and that is the only positive thing I can say. To start with, there is lag in the image on screen and the picture distorts if I move too quickly. I have tried a number of things to fix this without any luck. I have tried connecting it USB 2.O and USB 3.O ports with no change. I have connected it to a powered USB hub to make sure it had sufficient power to run, no change. This is connected to a powerful computer with a fast cpu, 24gb of ram and a dedicated graphics card and it still lags and distorts. I also found the picture to be dim. I have it in a room with professional video lighting equipment, and despite the reviews claiming it performs well in low light, I had the aperture open all the way and the image still appeared dim in a well lit room. I may exchange it and if I do, I will comment again on the review. What I can say for certain is that the unit I received is utterly useless as a web cam and I would advise everyone to not waste their time nor money on this camera.
