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.
All-Round & Video — A6700 (2023): Best-in-class autofocus and 4K/120p video in a compact APS-C body — the standout camera under £1,000.
