Elgato CPL Lens Filter for Facecam 4K

A circular polariser does one job and does it in a way no software filter can match: it rejects the polarised light bouncing off a shiny surface. On a webcam that means the reflection of a monitor in a window, the glare on a glass cabinet door, or the sheen off a lacquered desk behind the presenter.

This is the filter cut for Facecam 4K, fitted directly to the camera's lens barrel and rotated to dial the effect in against whatever the background is doing. It costs a fraction of a stop of light, so it is worth removing in a dim room. Weight is 47 g.
