Sue,
I recently acquired a lx100. It ended up retiring my Fuji x100 and Panasonic lx3. Both zoom ranges should take care of around 80% or more for most people. It's the super wide or the tele end where it could be an issue for some people. Given u already have the Nikon One system, have u thought about using it for where the lx100 or x30 won't cut it.
I chose the lx100 for the following
- fast aperture
- same m43 sensor as used in gx7, gm1 and 5
- 4k video plus 4k picture mode (vacations mostly)
- back to basics w/ control layout just like Fuji cameras I like
- wide fov is 24 not 28
- while it works like the Fuji x100, but for those times u aren't using the camera, hit the iAuto button and set it for 28 or 35 fov and hand it off to anyone to take a picture of u and your family.
- resume last zoom position (I leave it mostly at 50 fov)
I looked at both the rx10 and the fz1000.. They are great cameras and they cover a great zoom range. If u want an all in one, I don't think u can go wrong w/ either. But i am covered by my Fuji x bodies or m43 camera bodies when I need to go to either extreme.
I was looking for a good compromise between weight, high iso and compact size w/ a good evf. For me that ended up w/ the lx100. I could have gone w/ new gm5 and the pancake collapsible 12-32 as well, but it is not a fast zoom. Put a f2.8 zoom on it and u loose the compact size and weight. I don't print big enough to need more than 12mp anyway. My norm is 8x10 with occasional 13x19. If u print bigger, consider going to at least 16mp. Ymmv.
Good luck
Gary
