CFexpress Type A Compatible Cameras: Model-by-Model List

Short answer: CFexpress Type A cards are for cameras and readers with a CFexpress Type A slot. The CompactFlash Association says Type A is "as of now, exclusively compatible with select cameras by Sony". Below is every model we have checked against Sony's own Help Guide or support page, with a link so you can confirm it yourself.

A camera that accepts Type A cards does not mean every recording mode works with every Type A card. Sony lists a minimum card for each format; see section 4.

1. Sony cameras with CFexpress Type A support

Each Help Guide below states: "This camera supports CFexpress Type A memory cards and SD memory cards (UHS-I, UHS-II compatible)" and "CFexpress Type B memory cards cannot be used."

Two more Sony cinema models confirm Type A in different wording:

• ILME-FX5 / ILME-FX5B: "The unit records audio and video on CFexpress Type A memory cards (available separately) or SDXC memory cards (available separately)". Source: https://helpguide.sony.net/ilc/2630/v1/en/contents/card_about.html
• ILME-FX6V: Sony Japan support says CFexpress Type A and SDXC cards can be used, and SD cards of 32GB or less cannot. Source: https://support.sony.jp/electronics/support/articles/00255380

If your exact model or regional variant is not listed, check its own Help Guide.

2. Sony cameras that take SD cards only

These Help Guides say: "This camera supports only SD memory cards (UHS-II compatible)."

3. Card readers

• Sony MRW-G2: Sony Japan's product page lists it as a USB 3.2 Gen 2 reader for CFexpress Type A and SDHC/SDXC (UHS-I/II) cards, marked discontinued. Source: https://www.sony.jp/rec-media/products/MRW-G2/
• For any reader, look for "CFexpress Type A" in its specifications. Our Type A product pages note that a card reader is not included.

4. Before you record

1. Check each format's card requirement. The α7SIII Help Guide requires a "CFexpress Type A memory card (VPG200 or higher)" for XAVC S-I 4K (600 Mbps), while XAVC S HD (100 Mbps) lists a "CFexpress Type A memory card" with no VPG rating. The FX5's Recommended Memory Cards page marks VPG200 and VPG400 Type A cards as "Operation guaranteed" per mode.
2. VPG and Lambda Grove cards. Sony defines VPG 200 as a minimum of 200 MB/s continuous writing and VPG 400 as 400 MB/s. Our product pages state that no VPG certification is claimed, so where your camera names a VPG rating for a mode, Sony does not guarantee that mode with our cards.
3. Format in the camera. Sony: "Memory card formatted with a computer is not guaranteed to operate with the product. Be sure to format the memory card using this product."
4. Same file system in both slots. Sony: "When recording a movie on memory cards in both the Slot 1 and the Slot 2, insert two memory cards with the same file system." CFexpress Type A and SDXC use exFAT; SDHC uses FAT32.
5. Fragmentation. Sony warns that repeated shooting and deleting can fragment the card and interrupt movie recording; back up and format in the camera if it happens.
6. Firmware. Keep camera firmware current; our product pages ask you to confirm your camera firmware before ordering.
