The Canon EOS R100 keeps things simple with a single SD card slot that supports UHS-I V30 or U3 cards. Understanding the camera’s performance limits is key to picking the perfect media.

For stills, the R100 offers a continuous burst speed of 6.5 frames per second (fps). In the video department, it pushes a maximum internal recording bitrate of 120 Mb/s when shooting 8-bit 4K.

Why You Need a U3 Card

Since the 120Mb/s bitrate translates to a required sustained write speed of around 15MB/s, you absolutely must opt for U3 cards, not U1. To avoid dropped frames and ensure reliable video capture, your safest bet is to simply grab the fastest UHS-I U3 SD card you can find.

Recommended Capacity

Given the camera’s 24MP resolution, a 64GB card should be enough unless you frequently fire off long, continuous bursts at 6.5fps or shoot a ton of video.

However, playing it safe with a 128GB card is a wise move for better overall media management. I strongly advise against going below 32GB, as these cards often use an older file structure that can impose strict limits on video recording time. Stick with 64GB or 128GB for the best performance.

Recommended SD Cards For Canon EOS R100

Here are some of the best UHS-I cards for the Canon R100.

What Size SD Card Should I Get for the Canon EOS R100?

The good news is that the Canon EOS R100 doesn’t set a specific limit on SD card capacity, giving you flexibility.

Your ideal card size ultimately boils down to your personal shooting style and the file format you use.

If your workflow mainly involves shooting compressed RAW or JPEG photos, a reliable 64GB SD card should easily do the trick. However, if you are an avid shooter of 4K video—especially given the camera’s file sizes—you should absolutely consider a larger card for uninterrupted recording and peace of mind. For serious video content creators, a 128GB or even 256GB card is highly recommended.
