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.
Professional Sport, Wildlife, Portrait & Hybrid Shooting — A1 (2021): 50MP, 30fps, 8K — the Sony A1 is the most complete professional camera ever made.
