Best Canon Digital Rebel SD Memory Cards

´╗┐The Canon Digital Rebel uses Compact Flash memory cards. 8GB is the max card capacity that can be used.

A card over 8GB will not be recognized or the Digital Rebel will display an error. Additionally, a CF card will need to be formatted by the camera or with the FAT32 file system.

CF Memory cards come in two different sizes. The cards are referred to as Type I or Type II.

The difference between the types of cards is how thick they are. The width and length of the cards are the same.

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

The Type II spec were thicker so Microdrives could be used in the Canon Digital Rebel. A Microdrive was a tiny mechanical harddrive.

When CF cards were initially introduced they had high prices and very small storage capacities. Microdrives were the only solution to get large amounts of storage.

Microdrives are no longer being produced. Because they were mechanical, failure came from prolonged use or age. So they are nearly impossible to find used.

SD to Compact Flash adapters also use Type II slots. There are adapters that will allow you to use Micro SD or SD cards in a Compact Flash slot.

UGreen Memory Card Reader

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

The UGREEN card reader is USB 3.0 compatible. Using the card reader will provide transfer speeds that are much faster than what the Canon Digital Rebel can achieve.

The card reader can read these memory 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

A frequent problems with cameras that use CF cards are bent card slot pins. If a pin is bent, you could see a ‘unable to use card’ error.

To avoid bent pins, don’t force a CF card into the Canon Digital Rebel. The extra space for a Type II card allows a Compact Flash memory card to be aligned incorrectly.

If the compact flash card won’t effortlessly slide into the slot, remove it and check the alignment of the memory card. Also, check to see if these is any damage to the memory card.

If it looks fine, carefully align the compact flash card and make another attempt.
