I see no logical reason why Z9 AF wouldn’t be as capable or even surpass that of the Sony A1. It isn’t a hardware issue. Even the lower end Z7ii and Z6ii have the hardware capability to match that of Sony; it’s just a matter of programming. Perhaps the delay in the Z9 has been centered around the software. The hardware had been in place for a long time, perhaps the last several months have been perfecting the software, more specifically the auto focus system.I like his sentiment, but I have my doubts about the Z9 being better than the a1 or even the r3. History is just not on his side with that statement. Nikon has consistently been behind and now is a distant third in AF performance compared to the a1 and R3/5/6. I hope he's right since I'm planning to buy a Z9 - I'd like it to perform at that level - however, I think it's more likely to be at a9ii level. Again, I hope I'm wrong and I'm sure he has more sources at Nikon than I do (since I have, you know, none).
