The microscope is very good for his price. Good video quality at 4k, 2k, 1080, at 30fps (for 60fps choose 1080 and hdmi output only). IMX678 sensor (which is better than 6210 with IMX334 sensor) and usb3.2. The only negative is that i can't found anyware on the internet the manual of 6210s. There is only for 6210.
Very good product. Supplied lens provide (at least for me) sufficient magnification for 0402 SMD components. The camera worked under Win 10 via USB cable immediately without any extra drivers. It behaves like a standard camera, you can even use it in Teams or similar programs. However, there is very nice specialized program on Hayear pages, HAYEAR industrial microscope camera measure software. Free to download. http://download.hayear.com/content/?251.html
