Best Memory Cards for Panasonic GX85

In this guide, you’re going to see the 3 best memory cards for the Panasonic GX85, and also what to look for before buying one.

Having a reliable memory card is hands down the most important accessory for your camera.

Why? Because all of your shots and videos are stored there, and if that card goes corrupt, it’s nearly impossible to get the files back.

In this post, we are going to go through absolutely everything you need to know before buying the best memory card for the Panasonic GX85.

Panasonic GX85 Card Specifications:

• The GX85 has 1 x SD card slot
• Supports UHS-II speed cards
• 4K Video Recording and 9 frames per second burst

So, the Panasonic GX85 accepts 1 SD memory card slot, and supports a maximum speed of UHS-I cards. You can normally use UHS-II, which are faster, but the camera itself can not use the extra speed available. If you’ve never heard about these terms before, we’ll explain the difference below.

If you don’t care about the technical terms and just want something that works the best, look at the 3 best cards we listed right under.

Best 3 Memory Cards for Panasonic GX85

• SanDisk Extreme Pro 95MB/s UHS-I U3
• Lexar Professional 95MB/s UHS-I U3
• Transcend R95/W60MB/s UHS-I U3

What to Remember about Memory Cards

Here are a couple key things to remember when purchasing a SD memory card.

• ALWAYS buy more than one SD card
  • Memory cards don’t last forever
  • If you run out of space in the middle of shooting you have another card to pop in
  • Have two to four cards so you can setup a rotation between what’s in your camera and what you’re loading to your computer.
• Card size isn’t as important as buying more than one card
  • Card capacity is nice but having a backup card(s) is much more valuable for real life
• If you must, skip a meal rather than buy a cheap SD card
  • A bad memory card is going to slow down the ability to use your camera to its fullest
  • The card failing unexpectedly can also have dire consequences

Before going further into the 3 best cards and what makes them great for the Panasonic GX85, let’s look at what types of SD cards there are.

As you can see from the table above, we have cards that write at 2MB/s, and cards that go all the way up to 90MB/s. This comparison is directly from the SD association.

As of 2019, anything under 10MB/s is considered obsolete, and more or less hard to find.

What speed for the Panasonic GX85?

• For photographs: At least 10MB/s. The GX85 has 16 megapixels which isn’t a lot as far as file size goes, but this speed is absolutely fine. If you plan on doing lots of wildlife/sports shooting, then think about the 30MB/s speeed. Basically, the U1 or U3 markings will be fine.

• For videos: For Full HD video, 10MB/s (U1 or also known as V10) is alright. For 4K videos, make sure it’s at least 30MB/s (U3) to be on the safer side.

To put it simply, to get the best performance for photo and video, you want a U3 card for your Panasonic.

U3 is fast enough for anything you can think of, whether it’s 4K video recording or shooting sports at 9fps.

What about the UHS-I vs UHS-II? Simply put, UHS-II cards can read and write files faster, but unless your camera supports it, you will only see the benefit when transferring the files to your computer.

If you transfer gigabytes of files on a weekly basis, then a UHS-II card might be a smart choice, just remember that the GX85 won’t see any benefit from it.

All 3 cards we chose are U3 and very inexpensive.

SanDisk Extreme Pro 95MB/s UHS-I U3

The SanDisk 64GB Extreme Pro 32GB U3 is our favorite card, seeing as it’s inexpensive and provides writing and reading speeds near 90MB/s. It’ll handle the GX85 burst mode and 4K video with ease.

SanDisk is the most popular brand out there, and has been for more than 15 years. We have used it in all of our cameras, as well as phones and other devices.

It comes in 16GB, 32GB, 64GB, 128GB and 256GB sizes.

Lexar Professional 300MB/s UHS-II U3

The Lexar Professional 300MB/s UHS-II U3 offers faster speeds for both writing and reading files, but costs noticeably more.

However, we already mentioned that the Panasonic GX85 won’t benefit from it since it can’t take advantage of the extra speed offered by UHS-II (it will act like a UHS-I card), but if you transfer a lot of shots almost every day, you’ll appreciate the much faster transferring speeds to your computer.

Don’t have a memory card reader that supports such speeds? Luckily you get a free Lexar UHS-II reader along this card that will greatly reduce the waiting time. You also get a free downloadable Imaging Rescue software.

It comes in 32GB, 64GB and 128GB sizes. And in case you ever decide to upgrade to a newer model, chances are it’ll support UHS-II so you’re covered.

Transcend R95/W60MB/s UHS-I U3

The most affordable on our list, yet still UHS-I, is the Transcend 64GB UHS-I U3. In terms of reading speed it goes up to 95MB/s, while for writing the maximum is 60MB/s.

Transcend, just like Lexar above, gives you the option of downloading their free image recovery program and they both work pretty good in most cases. It comes in 64GB, 128GB and 256GB sizes.
