The Canon SX100 IS uses SD memory cards. The largest capacity SD card that will work in the SX100 IS is 32GB.

MMCplus and MultiMediaCard (MMC) can also be used. However, they are no longer made. If you have one, you can use it. If you do not have one, don’t buy one, they will be more expensive than an SD card.

SD memory cards described as SDXC or SDUC are not going to function correctly in the SX100 IS. These cards will be At least 64GB or larger, so they can easily be avoided.

The SDHC format was announced in 2006. All 32GB cards that are currently being produced will have almost identical performance. You cannot go wrong buying the cheapest class 10 name brand card. At the time of writing this, the PNY Elite 32GB SD memory card has the best price.

Best SD Cards

Be sure to select a card from a brand name with a good reputation, such as Lexar or SanDisk. Low-cost third party brands ought to be avoided.

Low-cost cards are more probable to experience data corruption, meaning that you’ll lose all of your photographs on the card. A minimal amount of savings on cost is not worth the decline of level of quality.

In a situation where you would like to save money, purchase a card with a reduced capacity. They tend to be a bit less expensive and you will not have to be concerned about the SD card losing your images.

Do not forget, SD card issues are rarely experienced. Only 2 cards have become corrupted out of the considerable number I have possessed over many years. Age may have played a role, as the SD cards were included with used digital point & shoots.

Canon SX100 IS SD Card Compatibility

Currently, four separate specifications of Secure Digital (SD) cards exist. The Canon SX100 IS can only use SD memory cards. The benefit is that there is an increase in the transfer rates and maximum capacity with the release of each updated spec.

Secure Digital memory card readers are backward compatible. A card reader built into a digital camera that can use SDXC cards will also be able to use SDHC and SD memory cards.

The card reader in the Canon SX100 IS will only work with the first two SD card specifications. SDXC or SDUC cards are not going to function correctly.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the SX100 IS.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the SX100 IS.
  • Secure Digital eXtended Capacity (SDXC) - The capacity of these memory cards range from 64GB to 2TiB.
  • Secure Digital Ultra Capacity (SDUC) - The capacity of these memory cards range from 4TiB to 128TiB.

Canon SX100 IS Memory Card Full Error

Attempting to use a card that has a storage capacity of 64GB or larger in size in the SX100 IS results in the digital point and shoot camera to show an error message.

Get an SD memory card which has a capacity of 32GB or smaller to fix the problem.

If you are using a memory card that has a storage capacity less than 32GB, and it is not working, try to format the SD card in the camera.

Speed, Class, & Capacity

SD Card Image Capacity

This is a quick estimation of how many large JPEGs you will be able to store on an SD memory card.

  • 4GB - 1920 images
  • 8GB - 3840 images
  • 16GB - 7680 images
  • 32GB - 15360 images

Memory Card Speed

Speed ratings for SD memory cards are established by sequential read and write speeds. The speed of the SD card is important for when many photographs need to be written or read from the memory card.

SD Card Speed Class Rating

SD Card Speed Class

The Class speed rating of an SD memory card is determined by the sustained write speed of the card. A Class speed rating of 2 means that the SD card can maintain a write speed of more than 2MB per second.

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s

The top rating an SD memory card can be given is Class 10. There are cards that are a lot faster than 10MB/s. Those SD memory cards use other technologies, such as UHS (Ultra Highspeed Bus), which have a different rating criteria.

Sustained write speeds of 2MB, 4MB, 6MB, or 8MB per second means the card has a speed class of 2, 4, 6, or 8. Cards that have write speeds of 10MB/s or faster are rated as Class 10.

MultiMediaCard Compatibility

The MultiMediaCard specification was established by Siemens AG and SanDisk in 1997. MMC cards are similar in dimensions to an SD memory card, but they are a little bit thinner.

MMC cards that will be able to function in the Canon SX100 IS consist of the 1st two generations. Compatible memory cards will be branded as MMCplus or MMC. Later versions won’t work correctly with the Canon SX100 IS

Steer clear of purchasing an MMC memory card. No one is actively producing MMC cards compatible with the SX100 IS. Thus, they are high-priced as well as being troublesome to come across pre-owned.


Buy an SD memory card for the Canon SX100 IS based on price. An expensive card isn’t going to improve performance. As long as it is a speed class 10 card, you will be fine. My recommendation is the PNY Elite 32GB SD memory card.
