Panasonic SD Memory Card Compatibility

The Panasonic G4 can use SD, SDHC, and SDXC memory cards. For video and burst shooting, it is necessary the memory card you use has a fast write speed.

An incorrect SD memory card can reduce the functionality of your camera.

Just want to have a memory card that works with the camera? Below is my suggestion on the SD card for use in your Panasonic G4:

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 cost of SD memory cards has greatly fallen since the release of the Panasonic G4.

Seeing as how low prices are, it doesn't be shrewd to buy anything other than a professional-level SD memory card.

SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards are great. I have not endured a card physically fail or corrupted data with any of those SD memory cards.

All the hassles I have had has been when using no-name unbranded SD cards. Seeking to save around a buck isn't worth it if your G4 is not going to work in the right way.

A great way to spend less money is to get a lower storage capacity card from a quality supplier. By making that choice, you'll know your shots are secure on the card.

Only SDXC, SDHC, and SD memory cards can be used by the Panasonic G4. Ensure you have the current firmware installed on your camera for the best overall performance.

Speed, Class, & UHS Ratings

Card Speed

The speed rating of an SD card is dependant on the continuous read and write speeds. Card file write speed is critical for clearing the camera buffer for continuous shooting and recording video.

Slows memory cards can cause a decrease in the number of continuous frames the Panasonic G4 can capture. This is because the buffer in the camera is not able to write data to the card fast enough.

When recording video, a slow memory card can cause recording to stop. The video file may also end up being corrupted. If you intend to shoot video, it is critical the memory card you use meets the required continuous write speed for video.

Card read speed is nice to have for transferring files to a computer or laptop. If you are filling up cards with images or video, a memory card with a fast transfer speed will cut down on the transfer 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.

The sustained write speed of an SD memory card is the factor that determines the Class rating. SD cards that have a minimum write speed of 10MB/s are labeled 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 find online will have a Class 10 rating. You can determine the class rating of an SD memory card by looking for a number inside of the C on the sticker.

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 is a feature often found in SDUC, SDXC, and SDHC cards. UHS cards to have faster read and write speeds.

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

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