Obviously, they work great on other brands' cameras as well.
Prices for 2018 Black Friday will be updated, as they happen.
The Lexar Pro SDXC card currently offers the best deal, and is at the top of the charts on most aforementioned cameras in terms of write speed.
However, the best SDXC UHS-II card you can buy right now is the Sony Tough, as it is just as speedy as the Lexar on most cameras, yet is made to survive conditions the others cannot. It is sure to bring you peace of mind, knowing that the files on it will be intact, even after subjected to extreme falls, cold/hot weather or what not.
64GB Lexar Pro SDXC 2000x UHS-II: $78.03 (price includes USB3.0 card reader)
64GB Sony SF-G64 SDXC UHS-II: $81.69
64GB Sony SF-G64T Tough SDXC UHS-II V90: $98.90
64GB SanDisk Extreme Pro SDXC UHS-II: $109.95 ($95.82 on AliExpress mobile app)
You can check-out all the actual speeds as tested by Alik Griffin.
EDIT: Here's a list of cameras with UHS-II memory slot(s). You can also add the Fuji X-T3 and Canon EOS R cameras to that list.
