Best Memory Cards For The Panasonic GX85


The memory card write speeds for the Panasonic GX85 aren’t great, but they’re still not terrible either.The fastest cards performed at around 35MB/s in camera. Still not as bad as Sony cameras but barely. This is usually do to an internal hardware limitation rather than a memory card flaw. 

Because of this 35MB/s bottleneck, choosing the fastest memory cards is a mute issues since they all perform relatively the same. However, when buying cards you’ll still have to consider if you want to go with less expensive cards or a more trusted brand.

If you still want to buy UHS-II memory cards then I personally would recommend any of them. None of them have given me any issues.

Best UHS-I Memory Cards

Since all the UHS-I memory cards perform about the same, you’ll want to either go with a more expensive top brand, like Sandisk or Lexar, or look for good deals from PNY, Transcend and Sony. 

Personally for this camera, I would probably buy one of the Sandisk Extreme cards. However, any of these following cards are great. 

The prices always bounce around as some cards get refreshed or discontinued, so make sure you compare a few.

Frequently Ask Questions


I’ve been doing these memory card speed tests for several years now and I get a lot of the same questions asked, so I’ll do my best to answer those here.

 

Do I need a UHS-II Memory Card? – While the camera works fine with UHS-I memory cards, you will gain significant buffer clearing speeds when using UHS-II cards. Not only that you’ll also see much faster speeds when transferring from your cards to your computer if you have a fast UHS-II memory card reader.

 

What’s the difference between U1 and U3 SD Memory cards? – The main difference has to do with minimum write speeds. U1 cards are guaranteed to write at a minimum speed of 10MB/s, and U3 SD memory card can write at a minimum speed of 30MB/s. Now of course there are many things that go on inside the camera that might not guarantee this, but it’s usually not the cards fault. You’ll also start seeing V10, V30, V60 and V90 written on memory cards. It basically a new way of saying the same thing. V30 is 30MB/s minimum write speeds, V60 is 60MB/s minimum and so on. 

 

What’s the difference between SDHC and SDXC with SD memory cards? – This has to do with the formatting of the card. SDHC cards are Fat32, and SDXC cards are exFat. SDHC means any card 32GB and smaller, and SDXC means 64GB and bigger.

 

My memory card is creating corrupt shots what do I do? – Unfortunately in this situation you likely have a bad card. There isn’t a lot you can do about this other than to replace your card. 

 

My memory card doesn’t work what do I do? – It’s likely you could have a bad memory card, but also make sure you always format your card in camera. This tends to reduce issues with cards not working or not performing correctly.

 

My buffer keeps getting fill when recording video? – This usually means you’re memory card is not fast enough and you’ll need get a faster card. If you already have a card on the list above, you should try a different brand. Not all cameras work the same with each card, different production cycles between cameras and cards can produce various results and there is no guarantee the cards I rated will work perfectly with your camera. Lexar, Toshiba, Samsung and Sandisk are usually pretty safe bets.

 

 

 


Best Memory Card For The Panasonic GX85 | Conclusions


The Panasonic GX85 seems to be pretty memory card friendly. It seems to take just about any modern card you throw at it with no complaints and because the cards all perform about the same, buying cards is easy, just buy your favorite brand. 

If you don’t have a favorite brand, I think one of the Sandisk Extreme cards is your best bet, just buy which ever is priced better at the time of your purchase.
