Olympus EM1 Mark II Best Memory Cards
UHS-II run almost 100MB/s faster than standard UHS-I cards so it really makes sense to go with UHS-II to get the full performance out of the camera. However, if you’re just shooting some street or shooting very casually, 45MB/s with the Sandisk Extreme UHS-I card is more than capable of handling those situations.
If you use the Olympus EM1 II as an underwater camera, street camera or just a casual biking, backpacking or around town camera, you will be absolutely fine using just a UHS-I card. Actually UHS-I cards still work great for video as well.
Me personally, I like having at least one UHS-II cards just for those situations where you will need to burst. For example, shooting kids. I also burst quite a bit with street photography when dealing with random people moving through the scene and I want multiple options of their position. One of the big selling points of the Olympus EM1 II, is that fast frame rate and quick buffer with UHS-II cards.
Here are the best memory cards for the Olympus EM-1 Mark II. Or at least the cards we recommend.
Olympus E-M1 II Top 4 Recommended Memory Cards
Lexar is still around and still the top performer. They are now owned by Longsys and are back at BHphoto. This test was done with the Lexar cards produced by Micron as I’ve yet to update my inventory.
Lexar, Sandisk, Transcend, Toshiba and Delkin are all fantastic cards. Prices are always jumping around so be sure to check them all out to get the best deal.
For the last year, a lot of Panasonic GH5 shooters are experiencing issues with ADATA cards, so I would avoid them for now. I excluded Toshiba from the list as well because it’s really tough to find those cards at a great price, so a lot of people aren’t shooting with them and I get very little feedback.
Sandisk Extreme Pro 300 64GB
Sandisk memory cards are always great cards for any camera. This Extreme Pro UHS-II version did perform slightly slower than some of the competition which is unusually. However 141 MB/s is still blazing fast and you would never notice the difference between of 7MB/s between this card and the other cards.
One thing really nice about Sandisk memory cards is the lifetime warranty. The downside is they are one of the most counterfeit brands out there, so be careful where you buy them. I’ve included BHphoto links so you can be absolutely guaranteed to get a certified card. – Amazon / BHphoto
Sony G UHS-II 64GB
The Sony G UHS-II are relatively new and they’ve been sort of stealing the show. The G version is the newest and is the card you want. The M version is very slow so avoid that. Sony cards only come with a 1 year warranty but they do come with free data recovery software you can download from Sony after registering your card. – Amazon / BHphoto
Delkin V90 64GB
Delkin UHS-II cards can almost always be found in my cameras mixed in with some Lexar and Sandisk cards. I have multiple UHS-II cameras with multiple SD card slots and don’t usually fill them all with one brand. These cards are fast and reliable. I like them and rarely hear of anyone having problems with them.
Lexar 2000X 64GB
Lexar like Sandisk are the titans of SD memory cards. I’m not sure if they have the same counterfeit issue Sandisk deals with but last year a lot of people were experiencing issues with their cards. It could have been a bad product run or people getting a batch of counterfeit cards. I’ve personally never had an issue with Lexar cards in any of my camera tests, and they work great in Olympus camera. Actually this was the fastest memory card in the Olympus EM1 II. – Amazon / BHphoto
Other Cards To Consider / Cards To Avoid
There is a lot of junk out there, a lot of counterfeit cards and a lot of white labeled cards. Right now ADATA is having some issues with Panasonic cameras so it’s possible Olympus cameras could have similar issues since. Both camera brands perform very similar and could be using similar hardware. Just my guess.
Brands like Hoodman Steel, ProGrade, Fujifilm, Panasonic are just white labeled cards. Meaning, they buy their cards factory direct from someone like Transcend or Delkin, then rebrand them. You’ll be better off buying one of the four cards recommended above.
Finding The Best SD Memory Cards Olympus EM1 II
With counterfeit cards being such an issue you really have to be careful where you get your cards. Absolutely avoid buying any memory cards from Ebay, unless you see Adorama or a trusted seller selling them. The best places to buy memory cards is either at a store like Best Buy, or BHphoto or Adorama. I’m hearing that Amazon is even having some issues since they sometimes mix inventory. So always make sure you buy your cards from the actual manufacturer and always check to see who fulfills the order before completing your purchase.
Best Memory Card 4k Video Olympus EM1 II
For shooting 4k Video every card on the list worked except the Samsung U1 card for whatever reason. Sometimes Samsung cards don’t work in Sony cameras as well. It might be the type of flash configuration they use.
The 4k video files of the EM1 II can output a 100mbps bit rate, but you’ll usually see less than that in most situations. 100Mbps translates to about 12MB/s so any card here easily can produce those speeds.
For people serious about 4k video, it’s sometimes nice to buy UHS-II cards that are fast at reading but slower at writing. These cards are often less expensive and allow you to still offload your footage from your cards to your computers quickly.
Best Memory Cards Olympus EM1 II | Bottom Line
UHS-II cards are the way to go in the Olympus EM1 mark II. Performance is so much better that it really doesn’t make sense to buy such a high performance camera and not take advantage of that speed.
However, it’s sometimes nice to have multiple cards and buying all UHS-II cards can be expensive. Even I sometimes run around with UHS-I cards in my UHS-II cameras when I’m just shooting landscapes or travel photography. You will save yourself a lot of money when buying big cards that are only UHS-I compared to UHS-II.
If you’re on a budget, what you could also do is buy a smaller UHS-II card for slot one (like a 32GB), set the camera to overflow to slot two, where you put a bigger UHS-I card. That way you still get the performance of the UHS-II cards most of the time, but still have the memory for those days when you’re shooting more than expected.
