Nisi ND 1.8（6段）Full Spectrum – ドロップインフィルター

Six stops of light reduction with zero color shift is exactly what I needed for wide-open daytime shoots. Sliding it into the drop-in slot behind the lens takes seconds, and I don’t have to worry about flare or vignetting anymore.

Finally, no more fiddling with screw-on ND filters that cause vignetting on my wide lenses – this drop-in design slots right in and is dead flat. The 6-stop reduction is perfectly consistent across the frame, which makes color grading in post a breeze.

Installing this drop-in filter was incredibly smooth—it slid right into the ATHENA system without any fuss. Cutting 6 stops of light exactly as promised, it let me shoot wide open in bright midday sun. My only tiny wish is that it came in a slightly sturdier case.
