NiSi ATHENA フルスペクトラム FS ND 0.6（2ストップ）ドロップインフィルター ATHENAレンズ用

For the price, I was pleasantly surprised how seamlessly this filter drops into the lens system—it locks into place with a satisfying click. The two-stop reduction keeps my highlights clean without shifting colors, which is exactly what I needed for outdoor shoots.

I was worried about compatibility with my lens setup, but this filter clicks into the drop-in slot with zero wobble and immediately balanced my exposure. The 2-stop reduction is exactly what I needed for shooting wide open in harsh midday sun without losing any sharpness.

It drops in smoothly and clicks into place without any wobble, which is a relief when you're swapping filters quickly on set. The glass feels solid and the color cast is minimal compared to other drop-in NDs I've tried.
