Best PowerShot A470 SD Memory Card

The Canon A470 can use SD memory cards. The maximum capacity SD card that can be used in the A470 is 32GB.

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

SD memory cards that meets the SDUC or SDXC specifications will not function in the A470. These cards will be At least 64GB or bigger, 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

Excellent memory cards are made by both SanDisk and Lexar. Inexpensive house brand names need to be avoided.

Low-priced cards are much more likely to experience data corruption, meaning you might lose all of your images saved on the card. A small amount of decrease in cost is not worth the decline in quality.

If you want to save a small amount of money, purchase a memory card with a reduced capacity. They are often a tiny bit more affordable and you will not have to be anxious about the SD card becoming corrupted.

Do not forget, SD card problems are a very rare experience. Only two cards have failed out of the various I have possessed over the years. Both of the memory cards were used third-party cards that were bundled along with the purchase of pre-owned cameras.

Canon A470 SD Card Compatibility

four different technical specs of Secure Digital (SD) memory cards are currently available. The Canon A470 is limited to using SD memory cards. Every new memory card technical spec boosts the maximum storage capacity and transfer speeds when compared to the previous 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 A470 is only compatible with the first two SD card specifications. SDUC or SDXC memory cards are not going to function correctly.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the A470.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the A470.
  • 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 A470 Memory Card Full Error

SD Card Contacts

Attempting to use an SD card that has a storage capacity of 64GB or larger in size in the A470 will cause the digital point and shoot camera to show an error.

Get a card which has a capacity of 32GB or less to resolve the problem.

If you have a memory card that has a capacity less than 32GB, and the card is not functioning correctly, format the memory card in the camera.

Speed, Class, & Capacity

SD Card Image Capacity

This is an estimate of how many large JPEGs you can expect to fit on an SD memory card.

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

Memory Card Speed

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

SD Card Speed Class Rating

SD Card Speed Class

The Class speed rating of an SD memory card is based on the sustained write speed of the memory card. A Class speed rating of 2 means that the SD memory card can maintain a write speed of a minimum of 2MB per second.

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

The maximum rating a card can get is Class 10. There are SD cards that are a lot faster than 10MB/s. Those SD cards use other technology, such as UHS (Ultra Highspeed Bus), which have a separate 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 technical standard was introduced to the market by SanDisk and Siemens AG in 1997. MMC cards look like a thinner SD memory card.

MMC cards that will be able to work correctly in the Canon A470 consist of the earliest 2 versions. Compatible cards will be branded as MMCplus or MMC. Later generations are not going to function correctly in the Canon A470

I wouldn’t recommend purchasing any MMC cards. No companies are at present manufacturing MMC cards compatible in the A470. Due to this fact, they are pricey and hard to find pre-owned.


Buy an SD memory card for the Canon A470 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.
