Know before you buy
This card is compatible with cameras that support the CFexpress Type B standard, including high-end mirrorless models from brands like Nikon, Canon, and Fujifilm. Always check your camera's manual or official compatibility list to ensure it supports the Type B form factor, as it is physically larger than Type A cards.
320GB provides a solid balance for most professional shoots, but your actual recording time depends heavily on your camera's bitrate and codec settings. For high-bitrate 8K RAW footage, you may fill this card in under an hour, so it is best used as a primary card for shorter sessions or as part of a multi-card workflow.
Yes, you will need a dedicated CFexpress Type B card reader to achieve the high-speed transfer rates this card is capable of. Standard SD or CFast readers are not compatible with the CFexpress interface.
The PRO-CINEMA series is specifically engineered to maintain consistent, sustained write speeds required for high-bitrate cinema cameras. While standard cards may experience speed drops during long, intensive recording sessions, this line is optimized to prevent dropped frames in demanding professional environments.
CFexpress cards naturally generate heat during high-speed data transfer and recording. This card is designed with thermal management in mind, but its performance can still be influenced by the camera's internal cooling system and the ambient temperature of your shooting environment.
