Panasonic GX850 Memory Card Compatibility

SDXC, SDHC, and SD memory cards are able to be used in the Panasonic GX850. Having fast write speeds is an essential aspect for video and continuous shooting.
The card you choose has a large impact on the performance of your camera.
Just want to have the best? Here is my recommendation on the card to use with your Panasonic GX850:

- UHS-I, U1, and Class 10 Speed Rating. Can sustain 10MB/s write speeds.
- Excellent choice for photos.
- Capable of recording Full HD (1920x1080) Video.
- Inexpensive with more than good enough performance.
- Larger capacities are available for a reasonable price.
Best SD Cards
SD memory cards are now much more affordable than at the time the camera was initially unveiled.
Due to prices being affordable, it is not going to be smart to get anything but a professional-quality SD memory card.
SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards are great. I have under no circumstances encountered a card physically fail or unusable data with any of those memory cards.
All of the trouble I have had has been with cheap unbranded memory cards. Trying to save a small amount of money is not worth it if your GX850 is going to have trouble.
If you want to reduce your cost, grab a lower capacity SD card from a high-quality manufacturer. That way, you’ll not have to be concerned about the photographs stored on the SD memory card.

Speed, Class, & UHS Ratings
Card Speed
The speed rating of an SD card is dependant on the sequential read and write transfer speeds of the card. The continuous transfer speed of a SD memory card is critical for clearing the buffer for continuous shooting and recording video.
A slow card can cause a reduction in the number of continuous images the Panasonic GX850 can capture. This is due to the camera’s buffer not being able to write to the card quickly enough.
When shooting video, a slow card can cause a sudden end to shooting. The video file may also be corrupted. If you are going to shoot video, it is essential the memory card you use meets the requirements of the GX850.
Card read speed is important for transferring files to a computer. If you have cards that are full, a card with a fast read speed will reduce the transfer time.
Speed Class Rating

The sustained write speed of an SD card is represented by the Class rating. Memory cards that have a minimum write speed of 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 memory card that you can get online will be Class 10. To locate the class rating of a card, try to find a number inside of a C on the front.
Ultra High Speed (UHS)

The Ultra High Speed (UHS) bus can be found in SDUC, SDXC, and SDHC memory cards. The UHS bus memory cards to achieve increased write speeds.
Three different specs have been made. The three are UHS-I, UHS-II, and UHS-III.
You can determine the UHS rating of a SD card by checking the front of the memory card. The presence of a Roman numeral I, II, or III on the front of the card, that will be the UHS rating of your 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
