Question about Panasonic Lumix FZ2000

I also own the Fz1000. Personally, I find the price difference a bit too big, but there are some clear advantages of the new version:

+ The lens no longer moves when zooming, as the lenses only move within the lens (-> the zoom no longer jerks like on the FZ1000 but is "smooth" and the focus stays on the subject and does not shift).
+ slightly longer zoom
+ 2 adjustable rings on the lens compared to one on the FZ1000
+ touch screen with better resolution
+ built-in grey filters (suitable for maintaining desired shutter speeds even in high light)
+ Material quality of the housing much better (unfortunately still not splash-proof) and 2 dials
+ Headphone jack
+ LOG profiles when filming
+ 10bit 4:2:2 output
+ no time limit when filming

So, I hope I could help you a bit with this list and that I didn't forget anything.

Already have the FZ1000. Why is the FZ2000 so much more expensive than the FZ1000?
