I forgot to mention that the other changed setting I was trying today was Focus Tracking with Lock on set to 1. I had been using 3 or higher.Thank you so very much! When you get a chance, I'd be interested to hear your thoughts regarding re-acquiring focus when the subject is closer than the camera is focusing.
That 400 f4.5 sounds like a very sweet lens! I need to find a lighter solution to my 600 f4! I can't hand hold the Z 800..... and I've never been that impressed with the 500 PF. But I haven't given the 500 PF a chance on the Z9......
I did not use it today but I have 3 normal methods if the camera is want to focus behind or in front of the subject. 1 is using my vid record button programed to recall shooting function hold and the only thing selected it turn af subject detections off. 2 is to use focus point memory recall on lens and the refocus on subject. 3 is to use manual focus ring. Which technique is used depends on how far away the subject is and how far behind the subject the lens is focusing and how much junk is around the subject.
