Recommended For
- Video crews recording high-bitrate footage on a compatible CFexpress Type B camera: SanDisk lists support for video up to 12K on compatible devices and VPG800/VPG400 ratings for the 400GB model. Check the camera’s supported recording modes before relying on a particular format or bitrate.
- Hybrid photo-and-video shooters using a CFexpress Type B camera who want one card for RAW bursts and video, plus faster transfers when paired with a compatible CFexpress 4.0 reader and host.
- Photographers and small production teams who prefer a single 400GB card for a shoot and want to reduce card swaps, while staying within a Type B camera’s documented compatibility and recording limits.
- Editors moving large photo or video files from location to workstation who have a compatible CFexpress 4.0 reader and computer interface; the card’s headline transfer speeds depend on the host setup.
