The Sony a7S III has dual memory card slots that are both compatible with CFexpress Type A cards and UHS-II-compatible SD cards. Designed for outstanding video performance as well as low-light shooting, the Sony a7S III (AmazonB&HAdorama) is the latest ultimate creative tool for video professionals and all types of hybrid still/video shooters looking for a high-quality full-frame 4K video camera in a compact form factor. Featuring a brand new 12.1MP back-illuminated full-frame image sensor with ultra-high sensitivity and 15+ stop wide dynamic range as well as an updated BIONZ XR image processor, the Sony a7S III offers in-camera 4K video recording up to 120 frames per second, 10-bit depth and 4:2:2 colour sampling and it allows up to 4K 60p 16-bit RAW output to an external recorder via HDMI Type-A connector, offering additional post-production flexibility. Although the Sony a7S III is primarily designed for video, it is also an ideal still photography camera for those who need top-notch low-light and higher ISO imaging performance and expansive dynamic. The Sony a7S III offers a native range of ISO 80-102400, which can be further expanded down to an impressively low ISO 40 and up to a shockingly high ISO 409,600, and it supports up to approximately 14 stops for stills and 15 stops for video, and 10 fps continuous shooting for up to 1000 uncompressed raw files for stills. Overall, the Sony a7S III is the best and most versatile 4K mirrorless camera on the market.

As we mentioned above, the Sony a7S III has 2x memory card slots that both support CFexpress Type A cards and UHS-II SD cards. Although SD cards and CFexpress Type A cards are not the same in size, both card slots in the Sony a7S III will accept either card type. So, if you have already had some fast SD cards, you can continue to use them since most of the Sony a7S III’s features work fine with either V60 or V90 cards. But, if you would like to use the camera’s most bandwidth intensive recording format – S&Q (‘slow and quick’) mode with 10-bit 4:2:2 recording, you will still need some higher-performance CFexpress Type A cards. So, in order to get the ultra high read speeds (transfer speed) and write speeds (fast buffer clearing time) to get the best out of your Sony a7S III camera, here we list the top recommended & fastest CFexpress Type A cards and SD cards for the Sony a7S III mirrorless camera based on the speed and price.
