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.
Compact Travel & Content Creation — A7C (2020): The A7C proves full-frame doesn't have to be bulky. Excellent battery life, reliable Eye AF and a vari-angle screen in a pocketable body is a compelling combination for travel and content creators. The A7C II improved on it, but the original remains a strong value buy.
