Best SD Card for Canon EOS M100
The Canon EOS M100 is a gem of a compact camera, blending a powerful 24.2MP APS-C sensor with a pocket-friendly design. However, I’ve seen many photographers pair this capable mirrorless body with sluggish, generic SD cards, only to be frustrated by “camera busy” messages during burst shooting. Because the M100 lacks 4K, you don’t need the most expensive cards on earth, but a reliable UHS-I card like the SanDisk Extreme Pro is essential for snappy performance. Let’s find your perfect match.

Best SD Card for Canon EOS M100: Detailed Reviews
SanDisk Extreme Pro UHS-I View on Amazon View on B&H
In my years of shooting with Canon’s M-series, the SanDisk Extreme Pro has consistently been the most reliable partner. While the M100 is an entry-level camera, its 6.1 fps continuous shooting speed can actually fill up the internal buffer quite quickly. This card features write speeds up to 90MB/s, which ensures that the buffer clears almost instantly, so you’re ready for the next shot. It’s a V30-rated card, meaning it handles the M100’s 1080p/60fps video with ease. The build quality is exceptional, being shockproof, temperature-proof, and waterproof. You might find cheaper cards, but the peace of mind knowing your vacation photos are safe on a SanDisk Pro is worth the extra few dollars. The only minor drawback is that the 200MB/s read speed requires a proprietary SanDisk reader to achieve, but even on standard readers, it’s plenty fast for offloading files to your laptop.

Samsung EVO Select View on Amazon View on B&H
If you want the best “bang for your buck,” the Samsung EVO Select is unbeatable. Often available at a fraction of the cost of “professional” cards, this microSDXC (which usually comes with a full-size SD adapter) is surprisingly robust. Don’t let the microSD format scare you; I’ve used these in M100 and M200 bodies for months without a single glitch. It offers enough speed to handle the M100’s maximum bitrate effortlessly. It’s U3 and V30 rated, which is the sweet spot for this camera. One thing I love about Samsung cards is their “6-proof” protection, covering everything from magnets to X-rays—perfect if you’re traveling through airports frequently. While it’s technically a hair slower than the SanDisk Pro in write-intensive burst scenarios, most hobbyists will never notice the difference. It’s the smart choice for those who would rather spend their money on a new EF-M lens than on storage.

Kingston Canvas Select Plus View on Amazon View on B&H
The Kingston Canvas Select Plus is designed for users who treat their M100 as a high-quality point-and-shoot. If you aren’t planning on shooting long bursts of RAW files at a football game, this card is all you need. It provides reliable Class 10 performance, which is more than enough for standard JPEG photography and Full HD video recording. During my testing, it stayed cool and didn’t exhibit any of the write errors that sometimes plague ultra-cheap generic cards. The read speeds of 100MB/s make it fairly quick to transfer your weekend photos to a PC. However, be aware that if you do try to shoot a long burst of RAW+JPEG files, the M100 will likely pause to “breathe” while the card catches up. It’s a “no-frills” card that does exactly what it says on the tin without costing more than a fancy lunch. For beginners, this is a solid, safe entry point.

Lexar Professional 1066x UHS-I View on Amazon View on B&H
The Lexar Professional 1066x (Silver Series) is a bit of a beast for the UHS-I category. While the M100 can’t utilize the absolute maximum write speeds of this card, having that overhead is fantastic if you’re the type of person who hates waiting for files to transfer to your computer. With a write speed of 120MB/s, this card actually outperforms the SanDisk Extreme Pro in some synthetic benchmarks. This is the card I recommend if you also use your SD cards in other, more demanding cameras or if you frequently shoot in RAW format and want the fastest possible buffer clearing the M100’s hardware can allow. It’s V30 and A2 rated, meaning it’s optimized for fast app loading if you ever use it in a tablet or smartphone as well. It’s slightly more expensive, but the build quality and consistent performance make it a top-tier choice for enthusiasts who want the best possible hardware.

SanDisk Extreme View on Amazon View on B&H
The “regular” SanDisk Extreme (the gold one) is the middle child in SanDisk’s lineup and is often the “sweet spot” for M100 owners. It offers 150MB/s read and 70MB/s write speeds, which fits the M100’s capabilities like a glove. You won’t feel held back by this card, even when shooting 1080p video at high frame rates. It’s essentially a slightly slower, more affordable version of the Extreme Pro. I often recommend this card to friends who are just starting out with photography; it’s much better than a generic card but doesn’t feel like an “over-investment.” It handles heat well, which is important because the M100 can get a bit warm during long video recordings. It’s a dependable, “set it and forget it” kind of card. While it lacks the ultimate “Pro” branding, for a camera like the M100, it provides nearly identical real-world performance for most shooting scenarios.

Frequently Asked Questions
Does the Canon EOS M100 support UHS-II cards?
Yes, the Canon EOS M100 is “backward compatible” with UHS-II cards, meaning they will work inside the camera. However, the camera’s internal bus is only UHS-I. You won’t see any speed improvement during shooting or while the camera clears its buffer. The only real benefit of a UHS-II card would be faster file transfers to your computer, provided you have a UHS-II compatible card reader. For most M100 users, sticking to high-quality UHS-I cards is much more cost-effective.
What size SD card should I get for a week-long trip?
For a week of travel, I usually suggest a 128GB card. While a 64GB card holds plenty of photos (about 2,500 JPEGs), it can fill up quickly if you start shooting Full HD video at 60fps. Video files on the M100 are roughly 440MB per minute at the highest quality. A 128GB card gives you enough breathing room so you don’t have to worry about deleting shots or offloading files to a laptop in your hotel room every night.
Why does my camera say “Card Full” when there is still space?
This is often a sign of a file system error or a “fake” SD card that reports more storage than it actually has. If you bought a very cheap, unbranded card, it might only have 8GB of actual storage despite saying 128GB. Always format your card *inside* the camera menu before use. If the problem persists with a reputable brand like SanDisk, the card might be failing, and you should replace it immediately to avoid losing your photos.
Can I use a MicroSD card with an adapter in the M100?
Absolutely! Many high-quality cards, like the Samsung EVO Select, are primarily sold as MicroSD cards with a full-size SD adapter included. In my experience, there is no performance penalty for using an adapter in the M100. Just make sure the adapter’s “Lock” switch isn’t accidentally pushed down, or the camera won’t be able to write any data to the card. It’s a versatile way to share cards between your camera, phone, or drone.
Is 1080p video recording demanding on SD cards?
The M100 records Full HD video at a maximum bitrate of about 60 Mbps (Megabits per second). This translates to about 7.5 MB/s (Megabytes per second). Almost any modern Class 10 or U1 card can handle this. However, I still recommend a V30 (Video Class 30) card. These cards are guaranteed to never drop below 30MB/s, which provides a massive safety margin. It prevents the camera from stopping the recording unexpectedly, which can happen with slower, older cards during long clips.
Final Verdict
For the vast majority of Canon EOS M100 users, the SanDisk Extreme Pro is the best choice. It balances speed, price, and world-class reliability, ensuring you never miss a shot during a burst. If you’re on a tight budget or just need a card for a weekend trip, the Samsung EVO Select offers nearly identical real-world performance for less. Regardless of your choice, stick to 64GB or 128GB to ensure you have plenty of room for both high-res photos and video.
