Canon EOS R5
Canon's EOS R5 – or as we say internally: Memory Card Monster – is without any doubt the "hottest" topic in 2020's camera world. And probably the most controversial as well. With 45 megapixels, 8K video including the ability to record RAW video internally, an amazing low-light autofocus and up to 20 fps in burst mode, the EOS R5 is an exciting photo-video hybrid for professional users.
But, and coming back to its nickname: The combination of high resolution stills and a fast burst mode, as well as the ability to record RAW videos internally, result in an enormous appetite for memory. This is probably the reasons why Canon has installed the, by far, fastest memory card controller that we came across in a consumer camera so far.
The Canon EOS R5 offers two memory card slots – one for SD and CFexpress memory cards each. The SD card controller with UHS-II support achieves an impressive 250 MB/s in real-world testing. If you wanna record 8K, 4K in the highest quality (All-I encoding or slow-motion) or just the maximum continuous shooting performance, CFexpress memory cards are what your techie soul is looking for.
SD cards can easily be used for photography and video recordings in normal quality settings like 8K/4K IPB. We recommend using UHS-II sd cards and at least 128 GB of storage space. For most 4K video recordings, a speed class of V60 or higher is required - the corresponding memory cards are marked with an label.
