Extraordinary response speed
Dramatically expand your photographic possibilities, with uncompressed continuous RAW shooting for fast-moving action such as motor sports and wildlife. Writing speeds of up to 700MB/s2  far outperform even the best SDXC cards, ensuring ultra-fast camera buffer clearance for responsive continuous shooting.

Dependable videography
Sony CFexpress Type A cards are optimised for continuous, high-bandwidth data writing, making them ideal for professional high-bitrate video recording, such as 4K 120p capture on cameras like the α7S III, where dependability is critical. For extra reassurance and video recording stability they also carry the VPG (Video Performance Guarantee) 400.

Ultra-efficient workflow
Dramatically accelerate your workflow with the optimised MRW-G2 card reader and ultra-fast read speeds of up to 800MB/s2 for data transfer and backup. Work seamlessly with high-resolution photos and high-bitrate video, to turn projects around at the speed of your imagination.

Rugged. Reliable. Ready.
Partnered with professional equipment like the α7S III, CFexpress Type A memory cards are perfect for the unpredictability of sport and location shoots or the hazards of outdoor expeditions. They are designed for extended professional use in the most challenging environments – from snow-covered mountains to sand-blown deserts – so you can shoot, swap and store with total confidence.

Scan and monitor your memory
Over time, flash memory wears out and no longer records data. When used with the MRW-G2 card reader, Sony’s Media Scan Utility automatically scans your CFexpress Type A memory card, keeping you informed of its condition so you can take action before it reaches the limit.

Recover lost files
Even when things go wrong, you can avoid disaster with downloadable rescue software for Sony memory card customers that recovers accidentally deleted files and corrupted photos and videos in various common formats.

Ultra-high-speed storage for innovative creators
The  CFexpress Type A standard is developed to provide compact cameras with the ultra-high-speed performance required for cutting-edge video creation. It maximises the capabilities of α-series cameras and the latest image-processing engines. For professionals seeking higher levels of performance and expression, this compact card is a must-have.
