Ciao, SD!

Engineered for Sony Alpha and FX lines, CFX4-A series unlocks the full potential of the cameras, supporting all video codecs including the slow-and-quick modes in finest HD / 4K in XAVC S-I format which requires up to 890 and 1200 Mbps respectively.

DESIGNED FOR ALPHAS

We know the strenuous demands required for working professionals in the field. We got you covered.

MAX SPEEDS OF UP TO 1865 MB/S READ AND 1750 MB/S WRITE

Burst speed for read and write are more than 6 times faster than the best SD UHS-II media, leveraging the maximum performance of the camera.

BUILT FOR 8K PRO PHOTO & VIDEO

Captures detailed, high-definition frames without drop off in performance as the capacity gets used by steady sustained write speed.

NON-STOP RECORDING TIME

The large capacities up to 1TB provide ample space for RAW footage. Creators are able to store more content non-stop in harsh and unforgiving environments.

ULTIMATE DURABILITY

Wise CFexpress Type A cards are protected against moisture, dust, X-ray, magnets and shock.

FAQ

CFexpress is an upgraded version of the CFast 2.0 and XQD. The main difference being faster speed.

Formally, CFexpress is a removable media standard created by the CompactFlash Association (CFA) in September 2016. The further CFexpress 2.0 standard was announced in February 2019, which includes three form factors defined in the standard (Type A, B and C). All form factors leverage the PCIe Gen 3 interface and use established NVMe protocols to offer better efficiency, optimized power and performance for professional imaging and video markets. For more information please visit (https://compactflash.org/).

It signifies the memory card has a minimum sustainable write speed of at least 400 MB/s.

According to the CFA association, Video Performance Guarantee (VPG) is a minimum guaranteed speed specification for writing continuous data streams from applications. The VPG specification is designed for stable high-res video recording (in Pro mirrorless and Pro video cameras). This can ensure that the video stream will be saved without interruptions or dropping frames. The VPG Logo is a “Clapper Board” with a number inside that specifies the minimum guaranteed write speed.

*Sony friends, please note it is important to have the VPG200 / VPG400 standard for your card to be able to unlock full video potential and better performance in buffer clearing.

Good luck, but that wouldn’t be wise. Size matters (Type A: 20.0 x 28.0 x 2.8 mm / Type B: 29.6 x 38.5 x 3.8 mm).
