My Z9 arrived and I have it all set and ready to go. Feels good in the hand and the build quality seems excellent. Love the flip-both-ways LCD screen , the feel of the buttons, and just the overall handling of the camera. Most of it is pretty familiar, but there are a few new things that I'll be adding to my Mirrorless AF book in the next update. I think this one is going to be really fun to shoot. I was playing with the AF with my cats and eye detection latches on really well - can't wait to try it on a more challenging subject.
