Best Memory Cards Canon R7 – 40 Cards Tested

The Canon R7, with its dual UHS-II SD memory card configuration, can take cards up to the V90 speed class. With its 30fps continuous shooting mode and 4k 340Mbps video features, you’ll need good memory cards. But do you need V90 cards? Not necessarily. Use this guide to help find the best memory cards for the Canon R7.

Recommended Memory Cards Canon R7

The Canon R7 has a dual UHS-II SD memory card setup.

For Photographers – The Canon R7 can shoot at up to 30fps, so a fast V90 card can be very helpful with clearing the buffer quickly.

For Videographers – the Canon R7 has a maximum bitrate of 340Mbps when recording 10-bit 4k60 video. This means the camera will need a data stream of at least 42.5MB/s.

I recommend starting with a minimum of a v60 UHS-II card, specifically the Lexar 1800x. That will be the best option for most people since it allows you to use all the camera features with no problems. Those who burst a lot should move up to a v90 UHS-II memory card; it will help a lot, especially with these 32MP files.

While it appears that a good UHS-I card will be fast enough to handle a 42.5MB/s data stream, UHS-I cards only guarantee a data stream of 30MB/s. To guarantee a 42.5 MB data stream, you’ll need to start with a V60 UHS-II card, which guarantees a minimum write speed of 60MB/s.

If you know you’ll never record 4k60 (since it has a pretty significant crop), and will only record 4k30 at the 230Mbps bitrate (28.75MB/s), then a UHS-I memory card is sufficient for this recording mode.

Canon R7 Speed and Buffer Tests

In-camera speeds are measured by shooting a series of bursts and calculating the time it took to clear the buffer against the amount of data written.

Also, be sure to see the UHS-I and UHS-II benchmarks when comparing cards USB Read and Write performance.

Choosing The Best Cards For Video

The Canon R7 has a maximum bitrate of 340Mbps at 4k60 10-bit using the H.265 codec. This very efficient codec will give a very high-quality image compared to the older H.264 codec. However, H.265 can perform poorly on older machines that don’t have graphics cards that can natively handle this codec, so keep that in mind when choosing your bitrate and record modes.

Here is a chart that shows the various bitrates and record times you can expect from various-sized cards.

Record Format	Bitrate	64GB	128GB	256GB
4k60p 10-bit	340Mbps / 42.5MBs	25min	50min	100min
4k30p 10-bit	230Mbps / 28.75MBs	37min	74min	148min
4k60 8-bit	170Mbps / 21.25MBs	50min	100min	201min
4k30 8-bit	120Mbps / 15MBs	71min	142min	284min
