Olympus SD Memory Card Compatibility

The Olympus E-PM2 has an SD card slot that can utilize UHS-I. The camera can work with SD cards up to 1TB in storage capacity.

To be able to get the best performance when taking pictures in continuous shooting mode, recording video, or transferring files, it is recommended to buy a memory card that has UHS-I. All of the fastest cards for the Olympus Pen E-PM2 will have UHS-I.

This is my recommendation for the best SD memory card for the Olympus E-PM2:

SanDisk Extreme Pro 128GB UHS-I SD Card

SanDisk Extreme Pro 128GB SD Card

  • The best performance at a reasonable price.
  • 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 release of the Olympus E-PM2, memory card prices have fallen and storage capacities have gotten larger. The difference in price between the fastest SD card and an average option is unexpectedly small. Price is more closely related to storage capacity, with the larger cards having a higher price.

Paying for the highest capacity cards is a good idea if you are going to shoot a large number of RAW files for action, wildlife, sports, or event photography. Another consideration could be if you are planning to replace your camera or use the SD memory card in other devices.

In my opinion, the SanDisk Extreme Pro line of cards are almost always the best option for most situations. They have fast read and write speeds, which means they have the best chance of working in future digital cameras or devices that also use SD cards.

I have had good experiences with PNY Elite Performance And Lexar Professional cards. I have not had images or files become damaged or unrecoverable on any of these cards. If that's a situation that did occur, all of them have image recovery software.

Issues I have encountered have been with generic SD cards. Having a low price or being a bundled accessory are the main selling points of these cards. Unfortunately, this is also the most common kind of SD card to be wrongfully advertised.

A label that promises Class 10 speed is easy to put on a Class 4 SD card. When the camera image processor starts writing data there is bound to be an error message or corrupted images if the card's write speed doesn't satisfy the requirements.

One of the largest controls over the price you have is the card capacity. You'll be better off by going one step down in capacity to reduce cost as an alternative to going with a cheaper brand. Read and write speeds are important factors that will affect your satisfaction with the Olympus Pen E-PM2.

Memory Card Reader

UGreen 4-in-1 Card Reader
There's a bright blue LED that bothered me. It is now covered in gaff tape.

The UGreen 4-in-1 memory card reader can use four different memory card formats. These cover all memory cart formats camera manufacturers implement in all but the latest professional-level cameras.

The UGREEN memory card reader has a USB 3.0 connection. The card reader's USB 3.0 transfer speeds will be faster transfer rates than what the Olympus Pen E-PM2 can reach transferring files with the USB mode.

There are overwhelmingly favorable customer reviews for the UGREEN card reader, which I agree with. I think it is a good product because the card reader has been recognized by all the computers (Windows, Mac, and Linux) I have used with it.

The cable prevents card slots from getting in the way of other devices or accessories that are being used in another USB or adjacent port.

When I searched for a more compact card reader that would be lighter for travel, I had to return a couple of orders. I encountered the most commonly seen problem mentioned in customer reviews, the memory card readers did not work with my computer.

The card reader can be used with the memory card formats below:

  • CompactFlash Cards
  • SD, SDHC, & SDXC Cards (UHS-I supported)
  • Memory Stick (MS), MS Pro, MS PRO-HG, & MS XC DUO
  • MicroSD, Micro SDHC, & Micro SDXC Cards

Olympus E-PM2 SD Card Compatibility

Only SD, SDHC, and SDXC memory cards can be used by the Olympus E-PM2. Ensure that you have the most up to date firmware installed on your camera for the best compatibility.

The newest memory cards, SDUC (Secure Digital Ultra Capacity), can not be used with the E-PM2.

You need to be aware of the four kinds of Secure Digital (SD) memory cards that are available for purchase. You can tell the difference between them based on their storage size.

  • 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.

Image Capacity

Image quality settings on the Olympus E-PM2 will determine the number of images you can store. Higher image quality options will cause bigger image sizes.

If you are going to shoot hundreds of RAW files, it can be a good idea to get a larger capacity card.

If you shoot JPEGs, you'd be better off purchasing another battery instead of a larger card. An SD memory card that has 32GB of space will have plenty of room for days of photos that would require the batteries to be recharged multiple times.

The limiting factor to just how many pictures you can take will likely be your camera batteries. Remember that, any time the camera is turned on, even if you're just scrolling through menu options or using the live view, that will eat away at battery life.

For low light conditions, like indoors or at night, the built-in flash can be useful. Shutter speeds won't be fast enough without the flash to prevent motion blur. Using the built-in flash is going to quickly deplete the camera batteries. These settings are when you need to own at least a couple of BLS-5 rechargeable batteries for the Olympus Pen E-PM2.

The following is an estimation of the number of high-quality JPEG images you can store on a SD card for the provided capacity:

  • 32GB - 9,280
  • 64GB - 18,560
  • 128GB - 37,120
  • 256GB - 74,240

Speed, Class, & UHS Ratings

Card Speed

Speed ratings of an SD memory card is dependant on the sequential write and read transfer speeds. SD card file write speed is very important for clearing the camera buffer for continuous shooting in addition to recording video.

Slows SD cards can cause a decrease in the number of continuous frames the Olympus E-PM2 can capture. This is because the camera's buffer is not able to write to the SD card fast enough.

With video, a slow memory card can cause a sudden end to the recording. The video file could also be corrupted. If you intend to record video, it is crucial the SD card you use meets the requirements of the E-PM2.

Read speed is important for file transfers to a computer or laptop. If you are filling up cards with images or video, an SD card with a fast transfer speed will save you time.

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 a memory card is related to the sustained write speed. SD cards that have a write speed of at least 10MB/s will be labeled 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 name-brand memory card that you can purchase today will be rated Class 10. To discover the class rating of an SD card, find a number inside of the C on the sticker.

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 can be gotten with SDUC, SDXC, and SDHC cards. UHS allows offers a way to improve file transfer rates.

Three separate specs have been created. The three are UHS-I, UHS-II, and UHS-III.

To find out the UHS rating of an SD card, look at the front of the card. If the memory card has UHS, a Roman numeral I, II, or III will be on the front of the 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
