Panasonic G4 SD Memory Card Compatibility

´╗┐The Panasonic G4 may use SDXC, SDHC, and SD memory cards. A memory card with fast enough write speeds is crucial for burst shooting and video.

The functionality of your camera can be decreased by using an incorrect SD memory card.

Want to skip the technical details? Here is my suggestion on the SD memory card to use with the Panasonic G4:

Check prices on: Amazon
  • 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

Memory cards are now substantially cheaper than at the time the camera was newly introduced.

Since the price range are low, it would not be cost-effective to spend money on anything other than a professional-quality SD card.

The best memory cards I use have been the SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance models. I have not suffered from a card break or corrupted data with any of those cards.

Every last hassle I have encountered has been because of no-name unbranded cards. Attempting to save a buck is not worth the cost if your G4 will not work as expected.

If you want to save some money, get a smaller storage capacity SD card from a high-quality supplier. By doing this, you will not have to fret about the photographs stored on the SD memory card.

Panasonic G4 SD Card Compatibility

Only use SDXC, SDHC, and SD cards in the Panasonic G4. Ensure you have the most recently released firmware installed on your camera for the best overall performance.

The newest memory cards, SDUC (Secure Digital Ultra Capacity), are unable to be used in the G4.

Four separate specifications of Secure Digital (SD) cards that you should know about. They are divided 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.

Image Capacity

Here’s a fast approximation of the volume of large JPEGs photographs you can expect to save on a card:

  • 16GB - 4,640 images
  • 32GB - 9,280 images
  • 64GB - 18,560 images
  • 128GB - 37,120 images

Speed, Class, & UHS Ratings

Card Speed

The speed rating of an SD memory card is classified by the continuous write and read speeds. The write speed of a card is essential for clearing the buffer for continuous shooting and recording video.

Slows cards can cause a decrease in the number of continuous photos the Panasonic G4 can capture. This is due to the camera’s buffer not being able to write data to the SD card fast enough.

With video, a slow SD card can cause recording to end. The video file may also end up being corrupted. If you are going to record video, it is important the memory card you use meets the required minimum write speed for video.

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

Speed Class Rating

/memory-cards/sd-card-speed-class.jpg
SD Card Speed Class

The Class rating of a memory card is based on the sustained write speed. Memory 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 find will be Class 10. You can check the class rating of a card by finding a number inside of a C on the label.

Ultra High Speed (UHS)

/memory-cards/sd-memory-card-uhs-i-rating.jpg
Example of UHS Rating

The Ultra High Speed bus (UHS) is built into SDHC, SDXC, and SDUC cards. The UHS bus memory cards to achieve faster transfer rates.

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

To find the UHS rating of a SD card, look on 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 rating of your 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

Determined by everything that was discussed is why the the 64GB SanDisk Extreme Pro is the best memory card for the Panasonic G4. The SD memory card also has good compatibility with other cameras.
