I own a 24-70mm f/2.8E ED VR on my Nikon d780 and lately I am just because of this, very frustrated with DSLR usage. That is also a reason why I want to go to Z. But I just don't want to. I still try to find a solution.
So... the problem is focus with D780 and 24-70 lens on a dance floor. Low light, flesh as a bounce. Every time I try to focus for example a first dance, a lot of shots are missed focus, focusing somewhere behind the couple, focus on guests.
When I do the same with prime lens 24mm, focus is always spot on. Always! So I assume something is with the lens. I assume it is slow and there for focus is not accurate and focus other subjects. Now I wonder, how to overcome this?
Should I upgrade for Nikon AF-S NIKKOR 24-70mm f/2.8E ED VR Lens? Is the newer version any better? Do you suggest other brands? Tamron or Sigma? Or maybe just buy Z6II with 24-70 Z and go with it?
Also there is another option, to buy Z6II and FTZ for the existing lens.
