Oh I don’t doubt that. But I don’t shoot Astro. Nor do I shoot BIF.
What I do shoot is people, film sets, events, studio, street and travel. Having switched from Nikon Z to Sony for these genres, Nikon isn’t at the party at this time. That’s both for bodies and lenses.
I also don’t think the Z8 will change this. Especially if kit size and weight to carry 8 hours a day is part of the decision for a jobbing photographer.
Look at the weight and bulk of the 24-70mm and 70-200mm Nikkor Z vs Sony GM2 versions. There’s a 500g saving straight off the bat for Sony for equivalent IQ and faster quad linear AF motors. No Z mount advantage there. NONE!
That said, Sony isn’t perfect, nor is Canon or Nikon. They all frustrate with their implementations at times. What is clear to me is that Nikon is pursuing niche BIF and the like with their sublime long exotics.
