What SD card for Canon R6?

Buy a UHS‑I U3 / V30 SDXC card (at minimum). 128GB is the best default for mixed photo/video.

Direct answer

Recommended: UHS‑I U3 / V30 SDXC (128GB sweet spot, 256GB if you shoot lots of 4K).

How to choose (quick steps)

1. Check the label: look for U3 and/or V30 (that’s your safe minimum).
2. Pick capacity based on video time: 128GB is a great default, go 256GB if you record lots of 4K.
3. Buy a known-good brand line (avoid unknown “bargain” cards for long 4K clips).
4. When it arrives: put it in the R6 and format it in-camera before important shoots (MENU → Setup/wrench → Format card).

What it means in practice

The R6 is a serious hybrid body, SD cards are the bottleneck more often than people expect. A good V30 card is the safe floor for reliable 4K workflows.

Do / avoid checklist

• Do: format cards in-camera before important shoots.
• Do: size cards by minutes of video, not just GB.
• Avoid: bargain cards for long 4K clips.
