Best Canon EOS M SD Memory Cards

SDXC, SDHC, and SD memory cards are designed to function with the Canon EOS M3. Continuous shooting and video need memory cards with high write speeds.

You can wreck the performance of your camera by using the wrong memory card.

Just want the best? Listed below is my suggestion on the SD memory card for use in your Canon EOS M3:

SanDisk Extreme Pro 128GB UHS-I SD Card

SanDisk Extreme Pro 128GB SD Card

  • Best value for the money.
  • 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

SD memory cards are now substantially less expensive than when the camera was initially sold.

Since costs are low, it will not make sense to choose anything besides a professional-quality SD memory card.

SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards have all been reliable for me. I have never encountered a card break or corrupted data with any of those memory cards.

Each and every complication I have had has been because of generic unbranded SD cards. Attempting to save a little bit of money isn't worth it if your EOS M3 is likely to have trouble.

If you want to reduce the cost, get a lower storage capacity card from a quality company. By making that choice, you'll not have to be anxious about the photographs stored on the SD card.

Canon EOS M3 SD Card Compatibility

The memory cards that will work with the Canon EOS M3 are SDXC, SDHC, and SD. For best performance, be certain that your camera is using the most up to date firmware.

The newest SDUC (Secure Digital Ultra Capacity) cards, can not be used in the EOS M3.

Four separate specifications of Secure Digital (SD) cards that you need to pay attention to. They can be told apart from the size of the SD memory card.

  • SD (Secure Digital) - 128MB to 2GB.
  • SDHC (Secure Digital High Capacity) - 4GB to 32GB.
  • SDXC (Secure Digital eXtended Capacity) - 64GB to 2TB.

Speed, Class, & UHS Ratings

Card Speed

The speed rating of an SD card is based on the continuous write and read transfer speeds. Card file write speed is important for continuous shooting in addition to video.

Slows SD cards can decrease the number of continuous photos the Canon EOS M3 can capture. This is because the camera's buffer is not able to write data to the card fast enough.

With video, a slow card can cause recording to stop. The video file may also be corrupted. If you are going to shoot video, it is important the card you use meets the required minimum continuous write speed for video.

Read speed is important for transferring files to a computer. If you are filling up cards with images or video, a memory card with a fast transfer speed will decrease the transfer 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 sustained write speed of a memory card is what determines the Class rating. SD cards that have a write speed of at least 10MB/s are rated as 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 brand-name SD card that you can find for sale today will be rated Class 10. You can find the class rating of a SD card by finding a number inside of the C on the label.

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 is a feature often found in SDUC, SDXC, and SDHC memory cards. The UHS bus makes it possible for increased file transfer rates.

Three separate versions have been specified. They are called UHS-I, UHS-II, and UHS-III.

To know what the rating of a memory card, look on the front of the card. If there is a Roman numeral I, II, or III on the front of the SD card, that will be the rating of your SD memory 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
