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.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
