Along with the Sony a7S III announced today Sony has also announced the world’s first CFexpress Type A memory cards that are currently only supported with the new Sony a7S III.
There are 80GB and 160GB versions and each card can write up to 700MB/s and read up to 800MB/s. The CFexpress Type A cards are ideally suited for high-speed continuous shooting of more than 1,000 uncompressed RAW still images, as well as 4K 120p movie recording at high bit rates with the Slow & Quick Motion function when paired with new Alpha 7S III, which features two CFexpress Type A compatible media slots, that also support UHS-I and UHS-II SDXC/SDHC cards.
Effective Heat Dissipation Design
The new CFexpress Type A memory cards are equipped with a heat sink to transfer heat generated by the card to the exterior when transmitting large amounts of data at high speed, using Sony’s original alloy with excellent thermal conductivity. This enables users to record for long periods of time even when recording 4K 120p video internally.
Keeping up with Sony’s TOUGH specifications, the new CFexpress Type A memory cards feature bending and impact resistance to protect precious data, even when frequently changing cards in the harshest environments. They are up to five times more resistant to drop impact and up to ten times more resistant to bending, compared to CFexpress Type A requirement standards, for outstanding durability. In addition, thanks to a specialised internal structure, they achieve an IPX7 water ingress protection rating and an IP5X dust ingress protection rating (IP57) for enhanced durability.
Accidents happen. Sony’s Memory Card File Rescue data recovery software allows users to recover accidentally deleted RAW images and 4K video from memory cards. In addition, Sony’s Media Scan Utility media diagnostic software will be updated to support CFexpress Type A cards allowing users to diagnose and receive a warning before the number of read/write cycles approaches the card’s limit.
CFexpress Type A/SD Card Reader
Optimised for the new CFexpress Type A memory cards, the CFexpress Type A/SD card reader (MRW-G2) provides SuperSpeed USB 10Gbps (USB 3.2 Gen 2) transfer speed, via its USB Type-C® connector, allowing creators to establish an efficient workflow when dealing with high-resolution image files, 4K video and other types of high-volume data. When combined with a CFexpress Type A card, it allows users to transfer data approximately 2.8 times faster than with conventional media. The MRW-G2 card reader can be used with CFexpress Type A and SDXC/SDHC (UHS-I and UHS-II) memory cards.
The new CFexpress Type A memory cards and card reader will be available in September 2020 and cost $198.00 / £209.00 for the 80GB version and $398.00 / £399.00 for the 160GB version, the reader will cost $118.00 / £129.00.
