Both the X-PRO2 and the X-T2 have 2 slots for cards. The first slot is a UHS-II slot, which can record as fast as 150 Megabytes/second in full duplex mode. The second slot is only a UHS-I slot that can only record as fast as 50 Megabytes/second in full duplex mode, provided that the memory cards are rated as fast as that.

  • There is more work involved in writing to a memory card that reading from the memory card.
  • It’s faster and easier to read from a memory card that it is to write to it.
  • Make sure that you check the write speed of the memory card. If it’s not on the box or on the card itself, it will be published on the manufacturer’s website.

Fuji has 3 settings for the memory cards:

  1. Sequential. That’s the default. The images are recorded to the memory card in the first slot. When it’s full, the camera will switch to the second memory card.
  2. Backup. All the images written to the memory card in slot 1 and also written to the memory card in slot 2. It’s slower than sequential.
  3. RAW/JPEG. The RAW image goes onto the memory card in slot 1 and the JPEGs go onto the memory card in slot 2. It’s not possible to change the order of the slots. RAW = slot 1 and JPEG = slot 2.
  1. It’s very important to turn off the camera before inserting or remove a memory card.
  2. Before removing any memory card, make sure that the indicator lamp at the bottom right of the back of the camera is off. That’s to allow the camera to finish writing the images to the memory card.
  3. Now matter what you have selected with the still images, movies are recorded on the first slot. No if, no then or but. Movies are always recorded onto the first slot. Then depending on your settings, they will be moved to the second slot, but that’s after the recording.
