64GB model: This card is suitable for photography on the R5, but does not fully function for video functions. it's just SPEED. normal sustain speeds are much slower. Therefore this card is listed as NOT SUPPORTED for video on R5. This works, but can cause buffering issues. All other models like 128GB and above are supported. This problem only exists with 64 GB. Plus, with 64GB, you only get 3 minutes of 8K RAW, so it's practically useless for video.
