Panasonic SD Memory Card Compatibility

The Panasonic GX7 is able to use SD, SDHC, and SDXC memory cards. Video and burst shooting need SD cards with fast write speeds to the card.

The SD memory card you buy has an important effect on the functionality of your camera.

If you are in a rush, here's the best memory card you can buy for the Panasonic GX7:

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

In the time since the launch of Panasonic GX7, the price of SD memory cards has come way down.

With prices becoming low, it would not make financial sense to spend money on anything but a pro-level card.

SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards are wonderful. I have not endured unusable data or a card become inoperable with any of those SD cards.

All the trouble I have had has been due to no-name unbranded memory cards. Hoping to save around a buck is not worthwhile if your GX7 will not operate properly.

If you want to reduce the cost, purchase a lower storage capacity SD card from a high-quality manufacturer. That way, you'll not have to be worried about the images stored on the card.

Speed, Class, & UHS Ratings

Card Speed

The speed rating of an SD card is determined by the continuous read and write transfer speeds. SD card continuous write speed is important for clearing the camera buffer for continuous shooting in addition to recording video.

Slows SD cards can decrease the number of continuous images the Panasonic GX7 can capture. This is because the buffer in the camera is not able to write to the SD card quickly enough.

When recording video, a slow memory card can cause a sudden end to the recording. The video file may also be corrupted. If you intend to capture video, it is essential the card you use meets the requirements of the GX7.

Card read speed is nice to have for transferring files to a computer. If you are filling up cards with images or video, a card with a fast read speed will decrease the amount of time it takes the transfer to complete.

Speed Class Rating

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

The continuous write speed of a memory card is the criteria for the Class rating. Cards that have a minimum write speed of 10MB/s will be labeled 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-name SD memory card that you can purchase will be rated Class 10. You can determine the class rating of a memory card by finding a number inside of the C on the label.

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 bus (UHS) is a feature found in SDHC, SDXC, and SDUC memory cards. UHS cards to achieve faster write speeds.

There are 3 separate versions. They are UHS-I, UHS-II, and UHS-III.

Look at the front of the card to find out the UHS rating of a card. If the card has UHS, a Roman numeral I, II, or III will be on the label.

  • 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
