NiSi ATHENA Full Spectrum FS ND 0.3（1級）插入式濾鏡（適用於ATHENA鏡頭）

I needed that extra stop for shooting wide open in sunlight, and this drop-in filter works perfectly with the lens system I already own. The glass is crystal clear and I can't see any color cast at all.

The drop-in design makes swapping between filters a breeze, and that single stop of light reduction really opened up my shallow depth of field shots on a sunny afternoon. Feels solidly built, too, no wobble once it's seated.

It handles that extra stop of light exactly as promised, letting me shoot wide open in harsh midday sun without clipping highlights. The drop-in install was seamless, and it feels solid enough that I don't worry about it rattling inside the lens.
