I"m not as convinced as you. I love the Nikon, only reason I've got GAS is because of the new puppy and want to take shed loads of photos of her
Thanks. Yeah I know that adapted won't be as good as native, that being said the adapted f-mount lenses on the Z's work extremely well, so much so that the difference is barely noticeable. I"m sure if you tried side by side you might detect something, but using in the real world I'm not seeing any discernible difference.
No clearly this is different, as whilst the mounts are different the manufacturer is the same. As above, the only reason for this insane GAS is to take photos of my puppy running around, and as you'll know trying to keep a single AF point on the head of a puppy as they're running around, darting left and right etc is extremely difficult. However, what I wouldn't want to do is swap over and find that animal eye-af doesn't work very due to using adapted glass. TBH I'm not even 100% sure using native glass on the A9 would get the shot, those puppies move faaaaaassssst
