77mm Variable ND Filter - Open Box
The sharpest, most color consistent variable ND filter in the world. The Solas NDX uses the highest quality optical glass, super-thin optical grade polarizing films, and many layers of Hoyaʼs patented multi-coatings on each of the 4 sides of glass. The result is a sharp, glare-free filter that produces superior quality images you can trust. A special patented layer baked into the optical formula that accomplishes the near impossible by controlling color shift resulting in a filter that maintains consistent color from 1.3-stops to 8.7-stops. Includes a step-up ring to work with the Moment Filter Mount.

Hoya Solas NDX Variable ND Filter — The Traveler's Video Exposure Control
The gist: A 1.3–8.7 stop variable ND with Hoya's patented color-lock layer — covering from bright overcast to direct midday sun in one filter while maintaining consistent color across the entire range.
- 1.3–8.7 stop range: Replaces a set of 3–4 fixed ND filters; dial from a light cloud reduction to 8.7 stops of deep cut without swapping glass mid-shot.
- Patented color-shift correction: An exclusive de-polarization layer baked into the optical formula prevents the color cast that plagues most variable NDs — footage stays color-consistent as you adjust.
- Maintains 180° shutter rule for video: Set shutter speed to 2× your frame rate, then use the VND to nail exposure without raising ISO or changing aperture — the standard for cinematic travel video.
- Front filter threads: Accepts a lens cap or additional filters (CPL, diffusion) on top — handy for stacking effects on a travel rig.
Hoya Filter USA confirms the Solas NDX uses a “de-polarization layer baked into the optical formula” for “consistent color from 1.3 to 8.7 stops” — a key differentiator from budget variable NDs that shift yellow or cyan as you rotate them.
Best for: Travel videographers and hybrid shooters who need one versatile filter for outdoor shooting in unpredictable light, without color-grading around a color-shifting VND. Skip it if: You only shoot stills — a fixed ND stack is cheaper if you never need to dial exposure live. Open-box condition; non-returnable. Runs ~$281 — check the current price before buying.
