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.

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