Let’s take a look at the best memory cards for Panasonic GH5.
The GH5 has 2 x SD memory card slots. They both support UHS-II cards, and since you’ll most likely be shooting at 4K, it’s almost must you get one of these.
As we usually say, don’t buy just any random cheap card. You risk losing all of your shots, and waiting too long for the buffer to clear. Imagine shooting a wedding, concert, or just traveling, and not being able to take pictures /videos because of your memory card…
In this guide, we’ve selected the 3 best cards. Either one will be great for the Panasonic GH5.
Speed Class of SD Cards
|Class||Min. Speed||Our opinion|
|Class 4||4MB/s||Too slow for most modern cameras. Skip it.|
|Class 6||6MB/s||A little bit better but unless you take 3 pictures a year, skip it.|
|Class 10||10MB/s||Good enough for most cameras with 20+ megapixels and Full HD video.|
|U1 (UHS)||10MB/s||Good enough for most cameras with 20+ megapixels and Full HD video|
|U3 (UHS)||30MB/s||Perfect for fast burst cameras, Full HD at 60fps and 4K video. This is what you want for the GH5|
As mentioned above, the GH5 supports UHS-II. It’ll perform faster in writing and reading than UHS-I, although UHS-I is still perfectly fine for 4K, let alone Full HD if you are on a budget.
If you send hundreds or thousands of photos/videos to your computer on a weekly basis, UHS-II is definitely your best friend.
Go with a 32GB or 64GB sized card, and buy a couple of these if you need lots of storage. It’s better than buying one huge card because you risk losing all of your files if that 1 card fails.
These are the best 3 SDHC/SDXC memory cards you can get:
- Lexar Professional 300MB/s UHS-II U3
- SanDisk Extreme Pro 300MB/s UHS-II U3
- SanDisk Extreme Pro 95MB/s UHS-I U3
Lexar Professional 300MB/s UHS-II U3
The Lexar Professional 300MB/s UHS-II U3 is a UHS-II card, so you can expect the fastest writing and reading speeds with the Panasonic GH5. It’s the perfect match for any UHS-II compatible camera that records 4K or has a fast continuous shooting speed. The buffer clearing time will be much much quicker which means you can take more shots. You will also send videos and photographs much quicker to your computer.
Writing speed is around 240MB/s, reading around 270MB/s. More than enough for even the most demanding video coming out of the GH5.
Don’t have a memory card reader that supports such speeds? Luckily you get a free Lexar UHS-II reader that’ll greatly reduce the waiting time. You also get a free downloadable Imaging Rescue software. It comes in 32GB, 64GB and 128GB sizes.
SanDisk Extreme Pro 300MB/s UHS-II U3
The SanDisk Extreme Pro 300MB/s UHS-II U3 is another UHS-II card that is worth every dollar. SanDisk has been in the memory card game for a longer time, and has more reputation.
However, both cards will get you the same writing and reading speeds. 4K videos, burst shooting at full resolution, it’s an easy task for these two cards. Close your eyes and pick randomly; or, choose the cheaper one (sometimes SanDisk goes for ~$10 less than Lexar).
These two models are literally the best on the market, and have been for some time.
SanDisk Extreme Pro 95MB/s UHS-I U3
The SanDisk 64GB Extreme Pro 32GB U3 is our favorite card for UHS-I slot. If you won’t record 4K/60p at 10bit, you don’t really need the most expensive card. If you want to save some money, then this is your best option. You could also use it in the UHS-II slot and still take pictures normally, but the buffer time won’t be as quick.
The speed makes it perfect for whatever you’re doing; fast bursts with large megapixel cameras, 4K video, let alone Full HD at 60fps. It comes in 16GB, 32GB, 64GB, 128GB and 256GB sizes.
Comparison of the 3 Memory Cards
|Lexar Professional 300MB/s U3||64GB||Writing files: ~240MB/s. Reading files: ~270MB/s|
|Sandisk Extreme Pro 300MB/s U3||64GB||Writing files: ~230MBs. Reading files: ~260MB/s|
|Sandisk Extreme Pro 95MB/s U3||32GB||Writing files: ~90MBs. Reading files: ~95MB/s|
What Brands are the Best?
Your photographs and videos are stored on a memory card, so you should definitely not try to save any money here by buying from unknown, cheap brands. While you save a few bucks, you probably won’t even get the advertised speeds, and are at a bigger risk of losing your shots.
We see too many beginners choosing the cheap route here, but until you transfer your shots to a computer/online, this is where they’re stored at. You want the memory card to be the most reliable piece of your equipment!
