CFexpress Type A Memory Card, 160GB

Sony CFexpress Type A TOUGH Memory Card — Fast, Rugged Storage for Sony Camera Travelers

The gist: The fastest and toughest memory card format for Sony mirrorless cameras, built to survive the drops and elements that travel inevitably brings without sacrificing the speed needed for 4K and burst shooting.

• 800 MB/s read / 700 MB/s write: Fast enough for continuous 4K RAW video recording and burst RAW photo sequences without buffer slowdowns mid-shoot.
• Survives a 15-foot drop: Rigidity-tested to 70N of force and drop-tested to 15 feet — handles the impact from a waist-height tumble on cobblestone or concrete.
• IP57 environmental rating: Resists dust, water submersion, extreme temperatures, X-rays, UV, and electrostatic discharge — airport security scanners won’t corrupt your footage.
• Compatible with Sony mirrorless bodies: Works natively in Sony Alpha cameras with a CFexpress Type A slot (a7 IV, a7R V, a1, FX3, and others) — no adapter required.

B&H Photo confirms the Sony CFexpress Type A TOUGH card features the IP57 environmental rating and 15-foot drop resistance, making it one of the most durable CFexpress cards available for field use.

Best for: Sony mirrorless users who shoot 4K video or high-speed bursts and travel in conditions where a card might take a knock or face moisture. Skip it if: Your Sony camera uses SD cards — CFexpress Type A requires a dedicated slot. Runs ~$120–$220 depending on capacity — check the current price before buying.
