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.
Beginner, Family, Travel — A6100 (2019): Best autofocus in its class for the price.
