DO NOT buy this camera for its advertised 60 FPS capability
Reviewed in Canada on March 1, 2019
I bought this camera specifically because of Logitech advertising its capability of capturing 720p video at 60 frames per second. After setting up the camera and experimenting with it a bit, it's clear to be that this is an absolute lie; it captures 30 FPS video at 720p but in 60 FPS mode the quality takes a severe nosedive and is clearly not native 720p. I'm not a lawyer but to me this seems like a case of blatant false advertising on Logitech's part.
The Logitech C922x Pro Stream Webcam ABSOLUTELY IS NOT capable of producing 720p (1280x720) video at 60 FPS. Instead it appears to capture something in the range of 360p (640x360) or possibly 480p (852x480), then scales it up to 720p and applies low-quality sharpening and denoise filters to hide some of the upscaling artifacts. (This will be a reference almost nobody reading this will understand, but the image quality at 60 FPS is similar to the game Xenoblade Chronicles 2 on Nintendo Switch while playing in handheld mode... yuck)
Take a look at my attached screenshots to see for yourself. I took these as fairly and honestly as I could, both with the same lighting conditions and both IN FOCUS. I repeat, both of these samples are PERFECTLY IN FOCUS to the best of the camera's capability at "720p". Amazon recompresses images uploaded for user reviews, but even the version that you're seeing should make the difference in "720p" when captured at 30 FPS vs 60 FPS plainly obvious.
This is not simply a matter of 60 FPS requiring better lighting, which is what you'd expect from a higher framerate requiring the camera to use double the shutter speed and therefore only be able to capture half as much light for each frame. If that was the case, the 60 FPS image would be darker and grainier; instead the difference is in resolution: the 30 FPS capture is reasonable-looking 720p while the 60 FPS capture looks more like 360p, or roughly one quarter the resolution.
One thing I must compliment as a positive is that this camera's video capture has much lower latency than I expected. There's almost no lag to speak of whatsoever, certainly less than 100ms in my estimation. This is much better than the ~1 second of latency that I've experienced with many webcams even under ideal lighting.
I should also mention the audio quality: it's bad, but no worse than you'd expect from the cheap microphones that webcams always get. You should probably just pretend the built-in microphone doesn't exist unless you have no other choice. Virtually any standalone microphone will sound better, such as an inexpensive (~$40) dynamic microphone on a cheap stand or a modest condenser mic on your desk a few feet away.
The reasons you should buy this camera are its decent 720p and 1080p quality at 30 FPS, but according to other reviewers its image quality is little (if any) better than Logitech's older, cheaper C920 camera which has the same resolution capabilities (minus the faux-720p 60 FPS mode), so only buy a C922 if it's on sale or if the extremely poor 60 FPS quality won't be a problem for your use-case. If this product was advertised honestly as a 60 FPS 360p, 30 FPS 720p, 30 FPS 1080p camera then I'd give it 4 stars, one star deducted for being overpriced and the microphone being worse than it really ought to be in 2019. Instead it's falsely advertised as a 60 FPS 720p camera which it absolutely is not, with a secondary 30 FPS 1080p mode. It gets 2 stars since the second part is still true and works better than I expected.
I will not buy another Logitech camera anytime soon. If I need to record 60 FPS video I'll be forced to put my cellphone on a tripod and use it instead of the "60 FPS" camera I just purchased for that specific purpose. Logitech's marketing department should be ashamed and I will be attempting to get a partial refund from Amazon.
