The 256GB Atlas Ultra UHS-II SDXC Memory Card from OWC / Other World Computing features a storage capacity of 256GB and takes advantage of the UHS-II bus to support advanced DSLR/mirrorless functions such as continuous shutter bursts and rapid shooting, as well as raw and JPEG captures. This card is also well-suited for video capture, including 6K, 4K, Full HD, and 3D video. It can achieve max sequential read speeds of up to 300 MB/s and max sequential write speeds of up to 250 MB/s. Thanks to its V90 speed class rating, minimum sustained write speeds are guaranteed not to drop below 90 MB/s.

To help facilitate card usage in almost any environment, as well as keeping your content safe, OWC built the Atlas Ultra with a design that is bend, shock, and X-ray resistant, as well as an IP67 rating, meaning it is dust and waterproof. It is also able to withstand temperature extremes from -13 to 185°F.

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.

Q: 5. Will this card work with a Canon 7D, Mk 4?

A: The Lexar 256GB Professional 1667x UHS-II SDXC Memory Card (2-Pack) is compatible with the SD card slot in the Canon EOS 7D Mark II and Canon EOS 5D Mark IV DSLR Cameras. However, the cameras do not support the fast speed of UHS-II cards. The SanDisk 256GB Extreme PRO UHS-I SDXC Memory Card, BH #SA256GBEPSD, is a less expensive option with the same performance.

Q: 6. Is this SF-M series card fast enough for 4k in Canon 5d4? The 256GB SF-E Series is too slow and chokes after a few minutes.

A: If you want to take advantage of 4K Video with the Canon 5D Mark IV, you'd need to use a CompactFlash card. This is because 4K is recorded at 500mbps which is 62.5MBps, so you'd need a card with a video rating of 65 or higher. The 5D Mark IV doesn't have a UHS-II card slot, so you cannot take advantage of V90 cards, so you'd have to resort to CompactFlash which the VPG rating is VPG 65 - which'll suffice for 4K video on this camera. We recommend something like the SanDisk 128GB Extreme Pro CompactFlash Memory Card (http://bhpho.to/2aGsUQf).

Q: 7. can I use in d850?

Q: 9. I have a small problem, I have a couple of sony SD card and they work Very well on my a7SIII but one of the cards take 2 minute too format on Canon 5DIV why? But after i format the SD it works just fine.

A: The Canon 5D Mark 4 is not fully UHS-2 compatible. You can use a UHS-2 card in the camera but it cannot take advantage of the faster speeds. That is why it takes longer to format in the Canon 5D Mark 4 than it does in your Sony a7sIII.

Q: 10. can i use this card for video recording on canon r6 mark ii?
