Designed primarily so that GH5 users will be able to fully embrace all of the features in its 2.0 firmware update, the Panasonic 64GB UHS-II SDXC Memory Cardfrom Panasonic 64GB UHS-II SDXC Memory Cardfeatures a storage capacity of 64GB and takes advantage of the UHS-II bus to support maximum read speeds of 280 MB/s and maximum write speeds of 250 MB/s. This card has also been designed with the V90 Video Speed Class rating, which guarantees minimum write speeds of at least 90 MB/s. All of this allows for users to immerse themselves the 4:2:2, 10-bit ALL-Intra and Long GOP video recording modes at resolutions of anamorphic 6K (4992 x 3744), DCI 4K (4096 x 2160), UHD 4K (3840 x 2160), anamorphic 4K (3328 x 2496), 4K HDR, and Full HD (1920 x 1080) with progressive frame rates of 23.98, 24, 25, 29.97, and 59.94 fps at bitrates of 200 and 400 Mb/s. In addition to its video capabilities, this card will support 6K and 4K photo captures.

UHS-II media achieves its speed through an extra row of pins and while this card has been designed for cameras that are UHS-II / V90 compatible, it may be used in devices that do not support UHS-II / V90. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-II and V60, which supports minimum write speeds of 60 MB/s, UHS-II and V30, which supports minimum write speeds of 30 MB/s, or UHS-I and U3, which also supports minimum write speeds of 30 MB/s. If your device does not support U3, this card is compatible with the U1 and Class 10 standards, each of which guarantees minimum write speeds of 10 MB/s.

Built for extreme conditions, Panasonic's 64GB UHS-II SDXC Memory Card utilizes Proof 7 technology, which provides protection against water, shock, magnets, x-rays, static electricity, and temperature. There is also a built-in fuse, and Smart Guard technology further helps to provide protection with power failure recovery and error guard, both of which can retain data in the event of a sudden power loss. A built-in write protect switch further helps to safeguard your content from being erased.

Related Questions and Answers

Q: 1. Will the ProGrade Digital 256GB UHS-II SDXC work with the original Blackmagic Pocket cinema camera? Anyone tried it?

A: On paper, the card should work without issue. UHS-II cards are backwards compatible with UHS-I card slots, since all that happens is that they read/write at UHS-I speeds. The Blackmagic Design Pocket Cinema Camera is also SDXC-standard compatible, which means theoretically any capacity of card in the SDXC standard should work.

Q: 2. Will these work on Panasonic S1H

A: Thanks for answers however one person indicated the V90s being fast enough for the S1H.. but the two pack 256 Cards are the V60s . Technically that should be more than enough to satisfy the 400 mb/s for this or the GH5S as they share the same format and data rate. Frankly I think that yes the V90s will work but is entirely overkill for a mere 50 Mb/s aka 400 mb/s

Q: 3. Is this card recommended for the Panasonic HC-X1?

A: Though these are UHS-II cards, they would still work quite well in your camera, you could also get away with: https://www.bhphotovideo.com/c/product/1431034-REG/sandisk_sdsdxxy_128g_ancin_extremepro_sdxc_128gb_card.html

Q: 4. Do these work with the Nikon D500?

A: Yes. And will take full advantage of the buffer rates of the camera.

Q: 5. Does a 250MB/s memory card have any distinct advantage over a 170MB/s memory card; either for continuous shooting, or downloading photos to a computer?

A: Hi James, Yes, a 250MB/s card does have advantages in shooting stills, capturing video and in downloading content to a computer. Both the read and write speeds are faster on that card than on the card you reference. You are less likely to notice a difference when shooting stills since both cards will likely keep up with the buffer of your camera but if you are shooting video you be able to capture video at the highest resolutions. In your workflow when downloading to your computer you will offload all of your content faster.

Q: 10. Will these cards work with the Fujifilm GFX 100? Thanks.
