Update September 2022: To all my viewers: thanks to @wrzone (see thread below) I was able to find out the actual CMOS sensor used on this microscope. I disassembled the small CMOS PCB from the chassis and found that it's a Sony IMX334 which is apparently a better sensor than the 377. Why the microscope outputs 12Mpx images I am not sure - but I guess it's a software feature.

Apologies for mispelling IMX377 with IMX337 but Lapsun themselves have mixed that up in their listings!

See pinned comment to find out what's the actual sensor inside the microscope!

Also apologies if I keep saying "Microsoft" or "Microphone"... :)

32:45 Conclusion

After publishing the video I measured the delay using a stopwatch and a camera on high speed shutter (iPhone with 3rd party app).

The delay I see is 15ms and this includes my Dell 2709W input lag which, according to Dell, is 6ms, but I guess it really depends on many factors. So it seems that the scope adds an extra 10ms approximately. I do not find that a problem to be honest.

here the picture to calculate the lag: www.cinematech.it/MyLinks/Lapsun_Lag.jpg
(Picture is grainy as it's high ISO to compensate for the high shutter speed!)

The item I purchased can be found here (I am NOT affiliated to Lapsun in any way and I do NOT get paid for this! Some links had expired and searched for new ones, I cannot be sure it's going to be the same product, please check with Lapsun)
