시네마 CPL 필터 - HERO 12 / 11 / 10 / 9

Took it snorkeling in Hawaii and the glare on the water was basically gone — way more detail in the reef shots. The rotating ring is stiff enough that it doesn't shift on its own but still easy to twist with one hand.

Shot waterfalls last weekend and this thing killed the glare on the wet rocks, way better than shooting without it. The threads spin on smooth and it stayed put even when I dunked the camera. Sky looks noticeably deeper too.

Took this to the coast and the glare coming off the water was basically gone, which I didn't expect from something that just clips on. The CPL also deepened the sky in my landscape shots without making everything look fake. Fiddly to rotate with cold fingers, but worth it.
