Hi,
Maybe, but mainstream is no longer going in the "Big is better" direction any longer . Travel is more complicated each day, having a practical system that one can fill in a bag is important. The 50mm 1.2 was designed, apparently, with the old Sigma art series in mind. If we add a super heavy duty body to it, for most people it will be too much
for most people.
Of course this camera is not for most photographers.
I hope Nikon does not take long, if the camera performs, introducing an Z8 that can help them recover a little bit of market share.
Decided the add a link to illustrate the point. He used to buy the big bodies, but they don't appeal to him any longer. Something akin to a D850 sizewise could be a winner.
A Z8?
Underscore: I understand your point, and I believe you are right, but I believe that is no longer as important for most photographers.
Best regards,
