Built for Professional Production

The durable enclosure withstands drops up to 5 meters and resists bending forces up to 70 newtons. Intelligent SmartIdle technology places the card into a lower power state when a compatible camera becomes idle, supporting efficient operation during demanding shooting sessions.
