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.
Hybrid Photography, Travel & Video On Sony Aps-C — A6600 (2019): The APS-C Sony that has everything — IBIS, real-time Eye AF, excellent battery life, and 4K/30p in a weather-sealed body.
Who should buy what
