NiSi ATHENA Full Spectrum FS ND 0.6 (2 Stop) Rear PL Filter for ATHENA PL Mount Lenses

I needed to darken my exposure by two stops without introducing any color shift, and this rear ND filter does exactly that while keeping the lens compact. The magnetic mount makes switching filters in the field incredibly fast, which saved me time during a tricky dolly shot. Definitely a solid buy f

Shot with this on a bright desert afternoon and the exposure stayed perfectly even across the whole frame—no color shift, no hotspots. The magnetic locking mechanism feels solid, and it’s honestly made me trust rear filters for the first time.

The rear placement makes lens changes so much faster on set, and the 2-stop density is exactly what I needed for wider apertures in bright sun. Image quality is impressively clean with no extra color cast that I can see.
