NiSi ATHENA True Color FS ND16/偏光（4級）插入式濾鏡，適用於ATHENA鏡頭

I was a bit skeptical about a drop-in filter that does both ND and polarizing, but the 4-stop ND cuts glare perfectly for outdoor shoots. The scissor mount clicks in securely without any light leaks, so it's a solid upgrade for my video rig.

The combined ND and polarizer in one drop-in is a huge time-saver on set, and the True Color coating means I'm not fighting any weird color casts in post. Rotating the polarizer through the lens housing feels smooth and solid, no play at all. Definitely keeping this in the kit for outdoor shoots.

Finally got to test this on a sunny coastal shoot and the way it cut glare off the wet rocks while maintaining natural color was impressive. The drop-in design makes swapping between lenses on set so much faster than screwing on separate filters.
