Panasonic SD Memory Card Compatibility

SD, SDHC, and SDXC memory cards can be used in the Panasonic GH4. An SD card with fast enough write speeds is essential for continuous shooting and video.

The overall performance of your camera can be greatly decreased by using an incompatible SD memory card.

If you are in a hurry, here's the best SD card you can buy for the Panasonic GH4:

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

Since the introduction of Panasonic GH4, the cost of memory cards has greatly reduced.

Since costs are low, it does not make financial sense to purchase anything but a professional-level SD card.

SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards have all worked well for me. I have not encountered corrupted data or a card break with those SD cards.

All of the problems I have experienced has been with cheap unbranded cards. Hoping to save a small amount of money isn't worth the cost if your GH4 is not going to operate correctly.

If you want to save some money, buy a smaller storage capacity card from a high-quality manufacturer. By doing this, you'll know your photographs are safe on the SD card.

Panasonic GH4 SD Card Compatibility

You can only use SDXC, SDHC, and SD cards with the Panasonic GH4. For best performance, be certain that your camera has the most up to date firmware installed.

The newest cards, SDUC (Secure Digital Ultra Capacity), are not going to be able to be used in the GH4.

You should be aware of the four different kinds of Secure Digital (SD) memory cards that exist. SD cards can be identified from the capacity of the card.

  • 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.

  • 128GB - 37,120

Speed, Class, & UHS Ratings

Card Speed

The speed rating of an SD memory card is based on the sequential write and read transfer speeds of the card. SD card file write speed is critical for continuous shooting in addition to video.

Slows cards can cause a reduction in the number of continuous photos the Panasonic GH4 can capture. This is because the camera's buffer will not be able to write data to the card quickly enough.

With video, a slow card can cause recording to stop. The video file might also end up being corrupted. If you intend to capture video, it is essential the SD card you use meets the minimum requirements of the GH4.

Card read speed is important for file transfers to a computer or laptop. If you are filling up cards with images or video, a card with a fast transfer speed will cut down on 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 Class rating of an SD memory card is based on the continuous write speed. SD cards that have a 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-name memory card that you can find today will have a Class 10 rating. To discover the class rating of an SD card, find a number inside of a 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 is a feature found in SDHC, SDXC, and SDUC cards. The UHS bus makes it possible to provide a way to improve data transfer rates.

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

Look at the front of the card to determine the rating of a card. The presence of a Roman numeral I, II, or III on the front of the SD card, that is the UHS rating of your SD 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
