GearScore™ Verdict — Which should you buy?

Video Exposure Control & Landscape Photography (67mm Lenses) — 67mm Variable ND2-400 Filter: The same variable ND performance as the 77mm version, sized for the 67mm thread common on APS-C lenses. Practical and affordable for video and landscape work. Avoid extreme ND settings to prevent the cross-pattern artifact.

Video Exposure Control & Daytime Long Exposures — 77mm Variable ND2-400 Filter: One filter instead of three. At 77mm it works on most standard zoom lenses. There's some colour cast and cross-pattern at extreme settings — step up to the Hoya or Breakthrough options if you need perfection, but for most uses this delivers excellent results at a fair price.
