Thanks all for your responses. I now have a new Zf and really like it for a candid, street, and scapes walk-around camera so far. After four days of use I pretty well have the settings locked in especially on the ibutton and in My Menu. Still some features like HEIF support and pixel shiftingI shooting that I haven't tried. IQ is very good and autofocus and other features similar to the Z8 are pluses. VR can be set to follow the focus point. The stills/video switch allows flipping between normal stills (color or set by Picture Control), B&W stills and video.
I am enjoying the ergonomics and, as I thought, the process of setting by dials is causing me to be more deliberate in making and adjusting exposures in those situations where subject is static. I have ordered an extended grip for large hand size from iWoodStore.com. I expect that will enhance handling considerably.
While I use the iPhone 15 ProMax for snapshots, I much prefer those Nikon bodies in hand.
