I checked the EOS 70D manual but wasn’t sure about the maximum supported SD card capacity. Can the Canon 70D use a 256GB SD card, and are there any card-type limitations I should watch for?

I just took a very quick look at the online manual, and right there on page 3, it says:

Compatible Cards

The camera can use the following cards regardless of capacity:

  • SD memory cards
  • SDHC memory cards*
  • SDXC memory cards*

*UHS-I cards supported.

I would advise having a read through the Wikipedia article on SD cards. Card capacities are not the main factor in determining compatibility. SD cards have gone through a number of generations – SD (SDSC), SDHC, SDXC, SDUC – and newer generations are not necessarily backwards-compatible. There are also different bus interfaces – Default Speed, High Speed, UHS-I, UHS-II, UHS-III, SD Express.

There is additionally this relevant FAQ on the Canon website:
What Memory Cards can be used with the camera? (EOS 70D)

If the card you are considering fulfils the compatibility criteria that Canon mentions, then I see no reason why you should continue to assume incompatibility.

Yes. The Canon EOS 70D supports SDXC cards, and the manual states it can use compatible SD, SDHC, and SDXC cards regardless of capacity. That means a 256GB card should work, provided it is an SDXC card.

The 70D also supports UHS-I cards. Compatibility depends more on the card standard and interface than just the size number on the label. In practice, a 256GB SDXC card has been reported working fine in the 70D, and larger-capacity SDXC cards are generally supported as long as they match the camera’s supported standards.

So when shopping, look for:

  • SDXC
  • UHS-I support (ideal)
  • A reputable brand

Avoid assuming newer bus types add benefit beyond the camera’s support; the key point is that the card must be backward-compatible and meet the 70D’s SDXC/UHS-I support.
