Why isn't Canon, Panasonic and others pushing XQD memory cards?

Correct me if I'm wrong, but it seems like Nikon is the only one pushing this koolaid.  Why is that?

Good question. I'll ignore the licensing crapola (Sony "owns" the technology).

The problem here is that XQD is a solution in search of a problem. It provides very high bandwidth that just isn't required by current image sizes. Even 4K 30p video can be easily handled by UHS-II cards. XQD is far above that.

The advantage of XQD is that the card becomes a PCI storage device, which puts it closer to the CPU, and removes the need for memory for buffering. I have a D850 (7 fps) and writing directly to the single XQD card, I can hold the button down pretty much forever. The camera never slows down.

So until we start seeing large sensors with a high frame rate, or 60p 4K video (or greater... 6K? 8K?) there's no compelling need for XQD.

Either the manufacturers will all move to greater MP counts and fps, thereby creating a need for XQD, or it will become another Memory Stick.

Finally, what we really want is CFE: same form factor, same speed and function (effectively), no license. We're waiting for a FW update for the D850 that enables CFE on that body. I'm hopeful.

I'd rather have a long bursting body than not.

Mind you, the greatest advantage for me is that when trans-
ferring the files to the desktop, in T3, it only takes seconds.

Light is free… capturing it is not!

I started on woodwinds (bassoon, sax), then piano/keyboards and voice in college, where I also started arranging and composing. Later on drums and bass, along with engineering and producing. I'm also a member of ASCAP.

Interesting, never paid much attention to who was using these cards and who wasn't.
