Panasonic SD Memory Card Compatibility

SDXC, SDHC, and SD memory cards will work with Panasonic GM1. Fast write speeds are an important factor for video and continuous shooting.

The functionality of your camera can be decreased by using the wrong SD memory card.

Just want to have an SD memory card that the camera can use? Below is my recommendation on the SD card to use with the Panasonic GM1:

SanDisk Extreme Pro 128GB UHS-I SD Card

SanDisk Extreme Pro 128GB SD Card

  • Best value for the money.
  • Capacities from 32 GB to 2TB.
  • Transfer speeds up to 170 MB/s.
  • Class 10 & UHS-I
  • Temperature Proof, Water Proof, Shock Proof, and X-ray Proof.

Best SD Cards

Like all things tech, the price of SD cards has greatly fallen since the release of the Panasonic GM1.

With costs becoming cheap, it would not make financial sense to get anything but a pro-level card.

The best memory cards I use have been the SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance models. I have never suffered from a card break or unusable data with any of those SD memory cards.

Every last problem I have dealt with has been because of generic unbranded SD cards. Seeking to save around a buck isn't worthwhile if your GM1 is not going to function correctly.

A smart way to save money is to find a smaller capacity SD memory card from a quality company. Because of this, you will not have to worry about the images stored on the SD memory card.

Panasonic GM1 SD Card Compatibility

The memory cards that will work in the Panasonic GM1 are SD, SDHC, and SDXC. For best performance, ensure your camera is using the most recent firmware.

The newest cards, SDUC (Secure Digital Ultra Capacity), cannot be used with the GM1.

You should know of the four different kinds of Secure Digital (SD) memory cards that can be bought. They are split up by storage size.

  • SD (Secure Digital) - 128MB to 2GB.
  • SDHC (Secure Digital High Capacity) - 4GB to 32GB.
  • SDXC (Secure Digital eXtended Capacity) - 64GB to 2TB.
  • SDUC (Secure Digital Ultra Capacity) - 4TB to 128TB.

  • 32GB - 9,280 images
  • 64GB - 18,560
  • 128GB - 37,120

Speed, Class, & UHS Ratings

Card Speed

The speed rating of an SD card is determined by the sequential read and write transfer speeds. The continuous transfer speed of an SD memory card is very important for continuous shooting in addition to video.

Slows cards can decrease the number of continuous images the Panasonic GM1 can capture. This is because the camera's buffer will not be able to write to the card quickly enough.

When recording video, a slow SD card can cause an abrupt end to recording. The video file may also end up being corrupted. If you are going to capture video, it is essential the card you use meets the minimum requirements of the GM1.

Read speed is nice to have for transferring files to a computer. If you have cards that are full, a card with a fast read speed will save you time.

Speed Class Rating

Example of where to find SD Card Speed Class
The 10 inside of the C means the card is Class 10.

An SD memory card receives a Class rating according to its sustained write speed. SD cards that have a minimum write speed of at least 10MB/s are rated as Class 10.

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

Every brand of card that you can buy will be Class 10. To determine the class rating of an SD card, look for a number inside of the C on the front.

Ultra High Speed (UHS)

Example of an SD memory card with a UHS-I rating.
The UHS rating of a card can be determined by a Roman numeral I, II, or III on the label of the card.

The Ultra High Speed (UHS) bus can be found in SDUC, SDXC, and SDHC memory cards. UHS allows provides a way to improve file transfer rates.

Three separate specifications have been created. They are UHS-I, UHS-II, and UHS-III.

To figure out the rating of an SD memory card, look at the front of the card. If there is a Roman numeral I, II, or III on the front of the SD memory card, that will be the UHS rating of the card.

  • UHS-I - Maximum transfer rate of 104 MB/s
  • UHS-II - Maximum transfer rate of 312 MB/s
  • UHS-III - Maximum transfer rate of 624 MB/s
