A camera needs a suitable SD card to function most efficiently. However, with all the complicated features of the cards, it might be tricky to find the best SD card for Canon 70D. Don’t worry! Here, we have a concise guide to help you buy this important camera accessory.


Factors To Consider Before Buying Best SD Card For Canon 70D

1. Compatibility

A good SD card is useless if it is not compatible with your camera. It can be daunting to figure out their well-suited mechanisms, though. So, let’s go through some of the criteria of memory cards to find the right one that meets the Canon 70D’s requirements.

2. Capacity

Memory cards can be of SD, SDHC, and SDXC types. Canon 70D supports all of these, so you simply need to focus on how much capacity you would need for your content while buying the card.

3. Speed Class (SC)

Speed class, UHS speed class, and Video speed class are the three factors you need to worry about regarding the camera’s transfer speed.

Canon 70D is very compatible with UHS-I SC (both U1 and U3). UHS-II can give you higher speeds, but with a UHS-II reader, preferably.
The speed class simply tells you the minimum write speed, which should be ideally 10 with this camera. The video SC gives you the capture and transfer speed of videos. V30 is sufficient for HD videos on Canon 70D.

4. Warranty – Durability And Price

A high value for the price is always essential. A warranty on your SD card ensures good quality, durability, and a high value for the cost.

After considering all the factors, we have listed memory cards that are highly compatible with Canon EOS 70D. We hope you find the best Canon 70D memory cards!
