Panasonic G1 Memory Card Compatibility

Panasonic G1 SD Memory Card Compatibility

The Panasonic G1 can use SD memory cards. The biggest capacity SD card that will work in the G1 is 32GB.

SD memory cards that meets the SDXC or SDUC requirements will not work properly in the G1. These cards can be easily avoided as they have a capacity of 64GB or more.

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.

Down below are SD cards that can be used in the G1. With all of the cards below, you will not have to be concerned about card errors or slow overall performance.

Best SD Cards

SanDisk, PNY, Samsung, and Lexar both manufacture good quality memory cards. Avoid picking cards from inexpensive no-name brand names.

Cheap cards are more inclined to encounter file corruption, meaning that you might lose all of your shots saved on the card. An insignificant amount of decrease in price is not worth the reduction in construction quality.

Buying a smaller capacity card is a savvy way to reduce expenses. They should be a tiny bit cheaper and you won’t need to worry about the SD card losing your shots.

Always bear in mind, SD card failures are infrequent. Over the years, I have only suffered from a couple of cards fail on me. Age could have added to the failure, as the SD cards were included with previously owned DSLRs.

Panasonic G1 SD Card Compatibility

The Panasonic G1 uses SD memory cards. There are 4 different technical specs of Secure Digital (SD) memory cards. Each updated memory card technical spec improves the maximum capacity and transfer speeds when compared to the prior standard.

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 Panasonic G1 will only work with the first two SD card specs. SDXC or SDUC SD cards will not be compatible.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the G1.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the G1.
  • 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.

Panasonic G1 Memory Card Full Error

SD Card Contacts

Trying to use a card that is 64GB or larger in the G1 will cause the point and shoot camera to display an error message.

Get a card which has a capacity of 32GB or less to avoid the error.

If you have a memory card that is 32GB or a smaller capacity, and it is not working correctly, format the SD card in the camera.

Speed, Class, & Capacity

SD Card Image Capacity

Here is an estimate of the total quantity of large JPEGs you will be able 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 memory cards is determined by sequential read and write speeds. The speed of the SD memory card is important in cases where many photos need to be written to the SD 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 SD memory 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 highest rating an SD memory card can be given is Class 10. There are cards that are substantially faster than 10MB/s. Those cards use other technology, such as UHS (Ultra Highspeed Bus), which have a separate rating specifications.

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.


Buy an SD memory card for the Panasonic G1 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.
