The Sony A6700 requires a SD UHS-II card with V30 speed rating for reliable performance. We recommend 256GB capacity as the sweet spot balancing storage capacity with affordability. The device supports up to 512GB, though most users find 256GB sufficient for daily use. Always choose from trusted brands like SanDisk, Lexar, or Kingston to ensure consistent performance and avoid data loss.
Is V30 enough for 4K 60fps?
Yes, V30 speed class provides the necessary 30MB/s minimum write speed for stable 4K 60fps video on the Sony A6700. Professional and advanced users often prefer V60 or faster cards for additional performance headroom and insurance during critical shoots.
