Panasonic GF1 Memory Card Compatibility

The Panasonic GF1 uses SD memory cards. The largest capacity SD card that can be used in the GF1 is 32GB.

MultiMediaCards (MMC) can also be used. However, they are no longer produced. If you have one, you can use it. If you do not have one, do not buy one, they will be more expensive than an SD card.

SD memory cards described as SDXC or SDUC are not going to work in the GF1. These cards will be 64GB or bigger, so they are simple to avoid.

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.

Below are a few possibilities to select from that will function correctly in the GF1. With any of the cards listed below, you won’t have to be worried about SD card errors or sluggish functionality.

Lexar, PNY, Samsung, and SanDisk both produce high-quality memory cards. Cut-rate third party brand names should be avoided.

Inexpensive cards are more liable to have file corruption, meaning that you might lose all of your images saved on the card. A small difference in cost is not worth the reduction of quality.

In the case that you would like to cut down on costs, buy a memory card with a smaller sized capacity. They should be slightly cheaper and you will not have to be worried about the SD card failing.

Understand that, SD card problems are rarely experienced. Only 2 cards have failed out of the considerable number I have acquired over time. Age could have contributed to the failure, as the SD cards were included with used DSLRs.

Currently, four different specifications of Secure Digital (SD) memory cards exist. The Panasonic GF1 is limited to using SD memory cards. The benefit is that there is an increase in the max capacity and transfer rates with the release of every 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 Panasonic GF1 is only compatible with the initial two SD card specs. SDXC or SDUC memory cards won’t function correctly.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the GF1.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the GF1.
  • 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.

Attempting to use a card that is 64GB or larger in size in the GF1 will result in the camera to display an error.

Get an SD memory card that has a storage capacity of 32GB or smaller to resolve the error.

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

The following is an estimation of the number of large JPEGs you can expect to keep on an SD memory card.

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

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

SD Card Speed Class
SD Card Speed Class

The Class speed rating of an SD card is based on the sustained write speed of the SD memory card. A Class speed rating of 2 means that the memory card can sustain 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 be given is Class 10. There are memory cards that are substantially faster than 10MB/s. Those SD cards use other technology, such as UHS (Ultra Highspeed Bus), which use a different 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.

In 1997, the MultiMediaCard specification was established by Siemens AG and SanDisk. MMC cards are similar in size to an SD card, but they are slightly thinner.

MMC memory cards that are going to function in the Panasonic GF1 include the 1st 2 versions. Compatible cards will be branded as MMC or MMCplus. Later versions are not going to work correctly with the Panasonic GF1

Steer clear of ordering an MMC memory card. Manufacturers are not currently manufacturing MMC cards compatible with the GF1. Consequently, they are tough to come across used and overpriced.

Buy an SD memory card for the Panasonic GF1 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.
