Nisi ND 0.9 (3 stops) Full Spectrum – Drop-in filter

The drop-in design made installation effortless—just clicked right into place behind the lens. I was worried about color shift, but it kept my shadows clean and neutral throughout a long afternoon shoot. Exactly the kind of subtle light control I needed without adding bulk.

Finally, no more fumbling with external ND filters for my ATHENA setup. The glass is perfectly clear and clean, and the 3-stop reduction is exactly what I needed to keep my aperture wide open in bright daylight.

The drop-in design makes swapping this in behind the lens a breeze, and the color cast is pretty neutral for a 3-stop filter on skin tones. I’ve left it on most of the day without noticing any sharpness loss in the corners. Glad I grabbed it for the ATHENA kit.
