SanDisk, PNY, Samsung, and Lexar both make reliable memory cards. Cut-rate third party brands ought to be avoided.

Cut-rate cards are much more likely to experience file corruption, meaning that you might lose all of your photos stored on the card. The reduction in quality is not worth the slight savings.

In a situation where you wish to reduce costs, purchase a memory card with a smaller capacity. They will be a little bit more affordable and you won’t have to be anxious about the SD card failing.

Even then, SD card problems are rare. Only 2 cards have become corrupted out of the various I have possessed over many years. Both of the memory cards were previously owned third-party cards that were included along with the purchase of previously owned digital cameras.

Speed, Class, & Capacity

SD Card Image Capacity

This is an estimation of the total quantity of large JPEGs you could expect to fit on an SD card.

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

Memory Card Speed

The speed rating for SD cards is determined by the sequential read and write speeds. The speed of the memory card is important for when many images need to be written to the memory card.

SD Card Speed Class Rating

SD Card Speed Class

The Class speed rating of an SD card is related to the sustained write speed of the card. A Class speed rating of 2 means that the 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 best rating a card can receive is Class 10. There are SD memory cards that are much faster than 10MB/s. Those SD cards use other technology, such as UHS (Ultra Highspeed Bus), that 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 standard was introduced to the market by SanDisk and Siemens AG in 1997. MMC cards look like a thinner SD card.

MMC cards that are going to function correctly in the Canon G7 consist of the original two generations. That comprises of the first cards branded as MMC and the 2nd gen MMCplus cards. Later generations won’t function correctly with the Canon G7

Steer clear of purchasing an MMC memory card. No one is at this time making MMC cards that will work in the G7. That’s why, they are really difficult to find pre-owned and not cheap.
