GearScore™ Verdict — Which should you buy?

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.

Video Exposure Control & Landscape Photography (82mm Lenses) — 82mm Variable ND2-400 Filter: The 82mm version covers the larger filter thread found on full-frame fast zooms. Same performance as the 77mm and 67mm variants — excellent value for an accessible variable ND. A practical addition for any full-frame shooter whose main lenses take 82mm filters.
