Long-time CPW follower Tig Tillinghast published a detailed CFexpress card review on Camnostic, it’s a must-read for recent purchasers of the EOS R5. He evaluates multiple cards for performance in many real-world scenarios, as well as price.

We recommend that you read through the article as each card has slight pros and cons, and the best card for you depends on your shooting style. His conclusions are that you can’t go wrong with one of:

• SanDisk 512GB Extreme PRO CFexpress Card Type B for $529.99 at B&H, Adorama
• Lexar 512GB Professional CFexpress Type-B for $599.00 at B&H, Adorama
• ProGrade Digital 325GB CFexpress 2.0 Cobalt for $549.99 at B&H
• Delkin Devices 512GB CFexpress POWER for $491.32 at Amazon, B&H
• Sony 512GB CFexpress Type B TOUGH for $649.99 at B&H

What’s most surprising is that the Delkin Devices 512GB CFexpress POWER, the most affordable of the bunch, shows comparable performance. Notably, Delkin also manufactures a 2TB CFexpress card which is 4 times the capacity but only double the price. Thanks to Tig’s positive review, we’re now listing all the Delkin CFexpress cards as we think they deliver tremendous value.
