Will this work with new fuji gfx 100s?

Will this work with new fuji gfx 100s?
Asked by: Walt
No, the only cards that the GFX 100S will take are going to be UHS-I and UHS-II SD cards. I would recommend using a UHS-II V60 at least to help reduce writing time.

Does it work with Blackmagic pocket 6k? Thanks.
Asked by: El
It does not, this is a CFexpress 2.0 card. The Pocket Cinema Camera 6K uses CFast 2.0 which is a different kind of media.

With the minimum sustained write speed of ...

With the minimum sustained write speed of 1500MB/s, how many shots can a Nikon D6 shoot to fill the D6 buffer?
Asked by: KN
Hi KN, We presented your question to our engineers. Below is there response. "The answer to that question depends on the following: 1- The camera buffer/DRAM size. How big is the buffer size? 2- The setting of the camera, specifically frames per second. How fast are you filling the buffer? 3- The photo compression which drives the size of each photo. How big the size of each photo is? 4- How fast the camera is clearing the buffer into flash media (How big is the pipe of the camera, i.e. does it use one lane vs. 2 lanes of PCIe) 5- The write speed of the card. How fast the card can clear the cache? If there is no bottlenecks, one could take photos continuously without filling the buffer (i.e. Canon 1DX Mark III) until the card is full. Hope this answers your question." Regards, JB (ProGrade Digital)

Will this work on Red Komodo ?
Asked by: Rency
The Red Komodo uses CFast cards not CFexpress cards. ProGrade Digital is one of four suppliers approved to work with the Komodo but they are currently out of stock.
