Panasonic GH1 Memory Card Compatibility

The Panasonic GH1 requires SD memory cards. 32GB is the maximum capacity SD card that will work in the GH1.

SD memory cards labeled as SDXC or SDUC won’t function correctly in the GH1. These cards can be easily avoided as they are 64GB or larger in size.

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 memory cards that will function correctly in the GH1. With any of the cards listed below, you won’t have to stress out over memory card data corruption or poor overall performance.

Lexar, PNY, Samsung, and SanDisk both manufacture excellent memory cards. Avoid getting cards from bargain-priced generic brands.

Memory card errors, including a loss of all of your shots caused by data corruption, is more likely to happen with low-cost cards. A tiny amount of decrease in price is not worth the decrease in build quality.

In the case that you really want to save a bit of money, just buy a memory card with a reduced capacity. They should be slightly more affordable and you won’t have to be anxious about the SD card failing.

Even then, SD card issues are uncommon. Through the years, I have only had two cards become corrupted. Age may have played a role, as the SD cards were included with used DSLRs.

4 separate specifications of Secure Digital (SD) memory cards are currently available. The Panasonic GH1 is limited to using SD memory cards. Every new memory card spec advances the maximum storage capacity and transfer rates when compared to the previous 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 Panasonic GH1’s card reader can only read the initial two SD card technical specs. SDXC or SDUC SD cards will not work.

  • Secure Digital (SD) - These memory cards have a maximum capacity of 2GB and are compatible with the GH1.
  • Secure Digital High Capacity (SDHC) - The capacity of these memory cards range from 4GB to 32GB and are also compatible with the GH1.
  • 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.

Trying to use an SD memory card that has a capacity of 64GB or larger in size in the GH1 results in the camera to display an error.

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

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

This is a quick estimate of the number of large JPEGs you will be able to fit on an SD memory card.

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

The speed rating for SD cards is established by sequential read and write speeds. The speed of the memory card is important in the event that many pictures need to be written to the memory card.

SD Card Speed Class
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 SD card can sustain a write speed of at least 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 get is Class 10. There are SD cards that are much faster than 10MB/s. Those SD cards use other solutions, 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.

Buy an SD memory card for the Panasonic GH1 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.
