Installing and removing the CF card on the EOS 5D Mark II


Although the thickness is different between the two types of CF (CompactFlash) cards, either one can be inserted into the camera. Also, Ultra DMA (UDMA) cards and hard disk-type cards can be used.
Installing the card

1. Open the cover.

  • Slide the cover as shown by the arrow to open it.

2. Insert the card.

  • As shown in the illustration, face the label side toward you and insert the end with the small holes into the camera.
    If the card is inserted in the wrong way, it may damage the camera. 
  • The card ejection button will stick out.

3. Close the cover.

  • Close the cover and slide it in the direction shown by the arrow until it snaps shut.
  • When you set the power switch is set to <ON> or <>, the number of remaining shots will be displayed on the LCD panel.
  • The number of possible shots depends on the remaining capacity of the card, image-recording quality, ISO speed, etc.
  • Setting the [ Shoot w/o card] menu option to [Off] will prevent you from forgetting to install a card.

Removing the card

1. Open the cover.

  • Turn the power switch to <OFF>.
  • Make sure the access lamp is off, then open the cover.

2. Remove the CF card.

  • Press the ejection button.
  • The card will come out.
  • Close the cover.
  • The access lamp lights or blinks while the picture is taken, when data is being transferred to the card and when data is being recorded, read, or erased on the card. While the access lamp is lit or blinking, never do any of the following. Doing so may damage the image data. It may also damage the card or camera.
    • ​Opening the card slot cover.
    • Removing the battery.
    • Shaking or banging the camera around.
  • ​If the card already contains recorded images, the image number might not start from 0001.
  • If a card-related error message is displayed on the LCD monitor, remove and reinstall the card. If the error persists, use a different card.
    If you can transfer all the images in the card to a personal computer, transfer all the images and then format the card. The card may then return to normal.
  • When holding a hard disk-type card, always hold its sides. You may damage the card by holding its flat surfaces. Compared to CF cards, hard disk-type cards are more vulnerable to vibration and physical shock. If you use such a card, be careful not to subject the camera to vibration or physical shock especially while recording or displaying images.
