Nikon appears to have addressed all of the main issues / wish-list items with Z6 & Z7 mark II's (I already miss the "S" designation... small potatoes there), but what remains to be seen are two SUPER important questions:
1. Will the AF speed / subject / face / eye tracking system
at least be on par with competing Sony & Canon bodies?
2. Can Nikon address their ongoing production & distribution issues?
None of these tech improvements matter if Nikon can't deliver products in a timely manner. We need lenses - people are literally yelling "Nikon, take my money!" and so many products are in constant backorder status. Even the non-S 24-200 is still nowhere to be found. Their lens roadmap milestones should not be updated until these products are at least reasonably available. People will get impatient and move on... especially when competing systems are showing some significant performance advantages.
I have a Z6 - I absolutely love it. I'm waiting on a few lenses (200-600 please!
). I'm planning on a Z6 II by mid-2021 (or whenever launch price drops). More than anything I want Nikon to succeed in the mirrorless market... I'm invested... I'll support them... but they really need step up their supply/demand game in a big way.
