Panasonic SD Memory Card Compatibility

The Panasonic GX850 can use SD, SDHC, and SDXC memory cards. An SD memory card with fast enough write speeds is necessary for video and burst shooting.

An inadequate memory card can greatly decrease the functionality of your camera.

Don't want to read the tech specs? Listed below is my suggestion on the card for use with the Panasonic GX850:

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

Memory cards are now significantly lower priced than when the camera was originally sold.

Due to costs being quite low, it is not going to make financial sense to spend money on anything but a pro-level memory card.

The best cards I own have been the SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance models. I have not suffered from unusable data or a card become inoperable with those SD memory cards.

All the trouble I have experienced has been because of cheap unbranded SD memory cards. Seeking to save around a buck is not worth the cost if your GX850 is likely to experience problems.

To cut costs, pick a smaller capacity SD card from a high-quality manufacturer. By doing this, you will not have to fret about the photos stored on the SD card.

Speed, Class, & UHS Ratings

Card Speed

Speed ratings of an SD card is classified by the sequential read and write speeds of the card. SD memory card write speed is essential for clearing the buffer for continuous shooting as well as recording video.

A slow card can cause a reduction in the number of continuous frames the Panasonic GX850 can take. This is because the camera's buffer is not able to write data to the card quickly enough.

With video, a slow card can cause recording to stop. The video file may also be corrupted. If you are going to capture video, it is important the card you use meets the requirements of the GX850.

Read speed is important for file transfers to a computer. If you have cards that are full, a memory card with a fast read speed will reduce the time it takes the transfer to finish.

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 sustained write speed of an SD card is the factor that determines the Class rating. Cards that have a minimum write speed of at least 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 card that you can get today will receive a Class 10 rating. You can determine the class rating of a card by searching for 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 (UHS) bus can often be found in SDUC, SDXC, and SDHC cards. UHS memory cards to have faster read and write speeds.

There are three different specifications. The versions are UHS-I, UHS-II, and UHS-III.

You can find the UHS rating of an SD card by checking the front of the SD memory card. A Roman numeral I, II, or III on the front of the SD memory card, that is the Rating of your SD 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
