Actually there is just one model, D5 with XQD slots. However, you can have the XQD slots replaced by CF. Nikon offers this as a user "degradation" option to be retrofitted at a qualified Nikon repair facility so is not something they actively will push, not at least in my part of the world. The national Nikon CEO was crystal clear on that question.
Bob, do you think it feasible to extract single frames from a 4K vid in lieu of just having faster fps?I tend to think that eventually it will come down to that. It may already be done, but I'm not up on the latest techniques of the sports shooters or other shooters who need high fps.
XQD has negligible market share and the companies who use it don't seem very committed to it since they don't use it across the lineup even in cameras that would benefit from the specifications. Also, Canon, Sandisk etc. do not have any XQD products which is enough to bury the others' half-hearted efforts.
The fact that Nikon has continued to use the XQD format with the D5 and D500 shows that they think there is a future for this format. The D500 alone will do much to make XQD more widely used. I wouldn't be surprised if it turned up on other high-end models such as a D810 replacement.
.........My first CF was 110 Euro and held 256MB of photos. Bummer.
...But for some reason mirrorless cameras that can acheive 15fps cannot do it with a live viewfinder (the EVF only shows an after the fact slide show), the technology apparently is not there yet. Without a live viewfinder I think the applications of 15fps are limited to special circumstances where the photographer does not need to follow the movement and there is plenty of room around the main subject in the image.
The D5, a lot. D500 as soon as it arrives on these latitudes.
Damned if you do and damned if you don't
