Best Memory Card for Canon EOS M5
The Canon EOS M5 remains a beloved mirrorless workhorse, but its 24.2MP sensor and 9fps burst rate can easily choke on an outdated SD card. I’ve seen many photographers miss critical shots because their camera was stuck “buffering” during a decisive moment. Since the M5 utilizes a UHS-I slot, you don’t need to overspend on high-end UHS-II cards. My top pick, the SanDisk Extreme Pro, provides the perfect blend of speed and reliability to keep your shutter firing without hesitation.

Best Memory Card for Canon EOS M5: Detailed Reviews
SanDisk Extreme Pro UHS-I View on Amazon View on B&H
If there is one card I trust more than any other in my gear bag, it’s the SanDisk Extreme Pro. For the Canon M5, this card is essentially the gold standard. While the camera is hardware-limited to UHS-I speeds, this card maxes out that potential with shot speeds up to 90MB/s. When you’re firing off a burst of RAW files at 9fps, you want that buffer to clear as quickly as possible so you don’t miss the next moment. I’ve used these cards in freezing rain and desert heat without a single file corruption incident. It carries a V30 rating, which is more than enough for the M5’s 1080p/60fps video. The only real “downside” is that it is slightly more expensive than generic brands, but for any serious enthusiast, the peace of mind regarding data integrity is well worth the small price premium.

Samsung EVO Select View on Amazon View on B&H
Samsung has truly disrupted the market with the EVO Select series. Usually sold as a microSD with a full-size SD adapter, don’t let the small form factor fool you. It is incredibly snappy and consistently hits its advertised speeds in the M5. I find these particularly useful because you can easily pop the microSD into a tablet or phone to preview your shots on a larger screen while traveling. For the price of one high-end card from other brands, you can often grab two of these, giving you a great backup option. The build quality is surprisingly rugged, advertised as water, X-ray, and magnet proof. While some purists dislike using adapters, I’ve found the connection to be rock-solid in the M5’s slot. It’s the ultimate “bang for your buck” choice for hobbyists who want high capacity without the high cost or any loss in performance.

Kingston Canvas Select Plus View on Amazon View on B&H
If you’ve just picked up a used EOS M5 and your budget is tight after buying lenses, the Kingston Canvas Select Plus is your best friend. It’s a no-frills Class 10 UHS-I card that does exactly what it says on the tin. With speeds up to 100MB/s, it handles the M5’s 24MP JPEGs with ease. You might notice a slight delay compared to the SanDisk when clearing a long sequence of RAW bursts, but for general travel and family photography, you likely won’t feel the difference. It’s also V30 rated, ensuring your video recording won’t abruptly stop. The limitation here is the slower write speed compared to “Pro” models, meaning the camera’s red activity light will stay on a few seconds longer during heavy use. However, for a card that costs less than a fancy lunch, it’s remarkably dependable for the everyday user.

Lexar Professional 1066x Silver View on Amazon View on B&H
For those who want to squeeze every last drop of performance out of the M5’s UHS-I bus, the Lexar Professional 1066x (Silver Series) is the way to go. It’s designed specifically for high-speed action and high-resolution capture. With read speeds pushing up to 160MB/s, offloading your photos to your computer at the end of the day is noticeably faster than cheaper cards. I’ve found Lexar’s “Silver” line to be a great middle ground for those who want professional-grade specs without paying for the “Gold” UHS-II cards that the M5 can’t even fully utilize. It handles the 7-9fps burst rate of the M5 elegantly. One minor caveat: to reach those maximum 160MB/s read speeds, you typically need a Lexar-specific card reader, but even with a standard reader, it remains one of the fastest and most durable UHS-I cards currently available on the market.

PNY Elite-X UHS-I View on Amazon View on B&H
PNY is often the unsung hero of the flash storage world. The Elite-X series is a workhorse card that I often recommend to those who frequently shoot video. It consistently maintains the V30 speed class, which means its minimum sustained write speed never drops below 30MB/s. This is crucial for the EOS M5 when shooting 1080p at 60fps, as it prevents dropped frames or recording errors that can ruin a take. The 100MB/s read speed is standard and reliable for transferring files. While it doesn’t have the “flashy” marketing of SanDisk or Lexar, PNY cards are often built with high-quality NAND flash that stands the test of time. I’ve used these for years in various mirrorless bodies and they’ve proven to be incredibly resilient. It’s a great “set it and forget it” card that offers a very stable experience for the average M5 shooter.

Frequently Asked Questions
Does the Canon EOS M5 support UHS-II memory cards?
Technically, yes, you can use a UHS-II card in the Canon EOS M5 because they are backward compatible with UHS-I slots. However, the camera hardware does not have the extra row of pins required to take advantage of UHS-II speeds. You will not see faster buffer clearing or better performance in-camera. The only benefit would be faster transfer speeds when moving photos from the card to your computer using a UHS-II compatible card reader.
What is the maximum SD card capacity for the M5?
The Canon EOS M5 supports SDXC cards, which theoretically allows for capacities up to 2TB. In practical terms, most photographers use 64GB, 128GB, or 256GB cards. I generally recommend 128GB as it offers enough space for a full day of shooting RAW+JPEG and video without being so large that you risk losing an entire month’s worth of work if the card is misplaced. Always format your card in-camera for best results.
Can I record 1080p 60fps video with a standard SD card?
To record 1080p at 60fps reliably, you need a card with at least a Class 10 or U1 rating, but a V30 (Video Class 30) card is highly recommended. The M5’s bitrates aren’t as high as modern 4K cameras, but a slow card can still cause the recording to stop randomly. Every card on our list is V30 rated or higher, ensuring you can record video smoothly until the card is full or the battery dies.
Why does my camera say “Busy” after taking several shots?
This happens when the camera’s internal buffer is full and it is waiting for the memory card to “write” the data. If you are using a slow or generic SD card, this process takes much longer. By upgrading to a card with a higher write speed, like the SanDisk Extreme Pro (90MB/s write), the buffer will clear much faster, allowing you to resume shooting almost immediately even after a long burst of photos.
Is it safe to use microSD cards with an adapter in the M5?
Yes, it is perfectly safe. Many high-quality cards, like the Samsung EVO Select, are primarily sold as microSD cards with included adapters. As long as the adapter is of good quality and the card is seated firmly, you will not experience any loss in speed or image quality. Many photographers actually prefer this setup because it makes it easier to transfer photos to mobile devices like tablets that have built-in microSD slots.
Final Verdict
For the vast majority of Canon EOS M5 users, the SanDisk Extreme Pro is the only card you’ll ever need, offering the speed required for its 9fps burst mode. If you are a casual shooter looking to save a few dollars, the Samsung EVO Select provides incredible value without sacrificing much performance. Regardless of your choice, ensure you stick to V30 rated cards to guarantee smooth video recording and a frustration-free shooting experience with your mirrorless camera.
