Best Canon EOS 10D SD Memory Cards

´╗┐The Canon EOS 10D uses Compact Flash memory cards. 8GB is the maximum card capacity that is compatible with the camera.

A card over 8GB will not be recognized or cause the EOS 10D to display an error message. Additionally, a memory card will need to be formatted in the camera or with the FAT32 file system.

Compact Flash memory cards come in two different sizes. The CF cards are known as Type I or Type II.

The only difference between the types is the thickness of the cards. The length and width of the cards are identical.

  • Type I - 3.3mm thick
  • Type II - 5mm thick

The Type II spec were thicker so Microdrives could be used in the Canon EOS 10D. A Microdrive was a little mechanical harddrive, the size of a CF card.

When CF memory cards were initially launched they had high prices and small storage capacities. Microdrives were the only option to get large amounts of storage.

Microdrives are no longer being built. Because they were mechanical, failure was a matter of time. So they are practically impossible to find used.

Another use of the Type II slot is for Compact Flash adapters. The adapters allow you to use Micro SD or SD cards in a Compact Flash slot.

The UGREEN 4-in-1 card reader is what I use with my CF cards.

The UGREEN card reader uses USB 3.0. Transfer speeds over USB 3.0 will be faster than the Canon EOS 10D.

The card reader can read these card types:

  • CompactFlash Cards
  • SD, SDHC, & SDXC Cards
  • Memory Stick (MS), MS Pro, MS PRO-HG, & MS XC DUO
  • MicroSD, Micro SDHC, & Micro SDXC Cards

One of the most common errors with cameras that use CF memory cards are bent card slot pins. If a pin is bent, you could see a ‘unable to use card’ error.

To avoid damaged pins, don’t force a CF card into the Canon EOS 10D. The extra space for a Type II card makes it possible for a CF card to be aligned incorrectly.

If the CF card won’t easily slide into the slot, take it out and check the positioning of the card. Also, check to see if the card is damaged.

If it looks undamaged, carefully position the CF card and try again.
