TELESIN GP-FLT-901�Overview
This�CPL Lens Filter�from�TELESIN�easily and securely attaches to the front of your GoPro HERO9 or Hero10 to help it capture images with reduced glare. Suitable for outdoor use, the filter can help darken the sky without reducing the exposure on your foreground subjects. The filter has a multilayer coating that improves light transmission and clarity.
Made from Gorilla Glass, the filter has a 9H hardness rating for durability in the field. It is waterproof, helping protect your camera, and the coatings help repel water and make it easier to clean should it get wet. The filter is held in its frame by a silicone gasket that keeps it attached to the camera and prevents water intrusion.
The filter is a circular polarizer, which means it features a linear polarizer to reduce glare and improve contrast, combined with a 1/4 wave retarder that randomizes the polarized light passing through the filter. This allows you to use the polarizer on optical systems without the image degradation that a linear polarizer by itself is prone to cause.
