CompactFlash & CFexpress Card FAQs

What’s the difference between CompactFlash and CFexpress cards?

CompactFlash (CF) cards are an older format commonly used in legacy DSLR cameras, while CFexpress cards are a newer, high-performance standard designed for modern professional cameras. CFexpress cards offer significantly faster read/write speeds, making them ideal for high-resolution photos, 4K/8K video, and continuous burst shooting. Always check your camera’s supported card type before purchasing.

Which CFexpress type does my camera need (Type A, Type B, or Type C)?

CFexpress cards come in Type A, Type B, and Type C, which differ in size and speed.

  • Type B is the most common and is used by many professional DSLR and mirrorless cameras.
  • Type A is smaller and used by select compact high-end cameras.
  • Type C is rare and mainly designed for future high-end video applications.

    Your camera will support only one specific type, so it’s important to confirm compatibility in your camera’s manual.

Are CompactFlash and CFexpress cards compatible with the same camera?

No. CompactFlash and CFexpress cards are not interchangeable unless your camera explicitly supports both formats. Some newer cameras use CFexpress Type B slots that look similar to XQD, but CompactFlash cards will not work in these slots. Always verify your camera’s supported memory format to avoid compatibility issues.

What speed rating should I choose for CFexpress cards?

For professional photography and video, choose a SanDisk CFexpress card with high sustained write speeds. Faster cards are recommended for RAW burst shooting, 4K/8K video, and high frame-rate recording. Using a slower card than your camera requires can result in dropped frames or recording limits.
