I started this reply in the "what's next for the Z6 thread", but realized it is its own topic.
I love the question, "Do we need more?", of course I do NOT from my Z6. It has so many features and functions, I get easily overwhelmed. Features in a camera is not the stumbling block in my photographic journey.
As many of us here, I would like the Z6 III to be modest (in today's terms) MP (24-36), but improve on ergonomics, operating speed, and soul. The Df (still have mine) did this in some ways. The Leica -- have never shot one -- seems to also. I want less features, less menus, less confusion. I think of Shooting Scenarios -- Street, Social Events Indoor, Outdoor events, Landscape/Nature, Portraits -- I want the camera to do more to support me in my intentions and easily switch between this scenarios both in settings I chose but maybe in some smart overrides or recommendations. I usually shoot in M with Auto ISO and mostly AF and mostly BBF. But sometimes I want manual, sometimes I want to hand the camera to a friend and be in full auto.
All of this is feasible, but really i just need to convince myself NOT to buy a Z6 III. It won't improve my photography!
And BTW, thank you NikonGear community.... while the name "gear" is in the name, this "place" on the web is always grounded in making images, seeing the world, and sharing with each other. The world needs more of that!
Cheers,
Rob.
