It's pretty hard to postulate about the advantages/disadvantages of this new camera... since all we have learned from the announcement is that 6 follows 5, and that Nikon is going to build at least one more high-end F-mount body. Was there anybody that didn't already know that?
Comon guys, every single of the D’s has been class leading in high ISO image quality and AF since the D3 11 years ago.
There is no reason to think the D6 will be any different.
On the contrary there are very good reasons to think that it will be significantly better than the D5:
- it will play the same role the F6 did, meaning that it will be the pinacle of the DSLR era, the last samouraï. Don’t under estimate the pride of those engineers with the best skills in the business. They have working literally day and night and weekends for 2-3 years on this camera
- the technologies developed for the D6, AF in particular, will be used in all subsequent high end Nikon DSLRs, including the D860/D900 and those are designed to be the best all round DSLR on the market and to extend the sales of F mount lenses for 3-4 more years
- the threat of the a9 II will have multiplied the motivation of Nikon to come up with a super competitive AF to sustain the sales of high end sport lenses until a Z9 is released and widely adopted, which will take some time regardless of its performance
- the 2020 Olympics take place in Japan. For the Nikon DSLR guys, this is the climax of their careers
Simple logic coupled with in-depth knowledge of Nikon and of the Japenese corporate world.
Some of this is comon to Canon btw, but they have shown less AF skills, a different approach for commonalization of high end camera components in all round bodies and there is zero symbolism associated with the 1DX mkIII naming convention.
Having already sold many F mount lenses I am unlikely to buy a D6, but I can nonetheless recognize it is going to be an amazing tool.
Cheers,
