I purchase this lens for my SJ7 Star. It need little adjustment to fit on SJCam I have used teflon tape. It serves the purpose but not that great. Reflections from car window has been reduced but not disappeared. Overall satisfied as per price point.

It is wide enough not to get vignetting on a 170° lens. Is not the best UV filter, OK for what you pay for. OK for what it is as a lens protector. 22mm wide opening.
