D-Lux is not Leica made, but Panasonic. Only latest one has EVF and decent size of the sensor. It is not serious cameras, they are very nice, advanced P&S. Leica lenses do nice rendering on them. But as any P&S with zoom, they feel very fragile.
Creative part sound familiar to me. I'm most creative with film rangefinder cameras and iPhone.
How often do you use 70-200? I still have it, but using it few times per year for very simple photography. It is just a tool for me. I think, creativity has two types. One is to create something in front of the lens. Lineup objects, like Lego, put the light... 70-200 is great portrait lens. If you know how to create portraits, this lens will do.
Normal zoom is also tool, too universal some times... And wide zooms... you really need to like wide SLR distortions. IMO.
How is it possible to be creative with wide, normal and tele zooms , I don't know. I wasn't, it was whatever they asked me photography where I was trying to be creative. And one thing I noticed, I was switching from any zoom to the fifty. To be more creative. Don't know if it works for many, but this is how it works for me. And if you look at known photographers like Bresson, Bown and Karsh, they are different for creativity approach. Street or what is available, what is available or just one extra light source sometimes; full theatrical light kit. Yet, all three had minimum amount of primes and cameras.
Here comes another type of creativity. You observe, read and take it. At some point you might realize what your creative vision or just vision is working with one specific focal length. It is not primes, but often the prime. Bown used 80mm most, Bresson used mostly 50 and Winogrand used 28.
Karsh was using assistant to model the pose for actual sitter and check the light. Bown was walking in circles around the sitter and waiting for the taker to show up. Bresson... he was walking in and sitters often didn't even know then portrait was taken. Karsh used studio camera with one lens, Bown used SLR and Bresson used Leica.
It is Leica which allows you to be creative within environment. I stopped looking at images in dedicated threads at P.O.T.N. long time ago. Instead I like what is showing up at Leica Blog under M cameras photography. This is where Leica photography is for me. Q, T, SL isn't Leica, IMO. Most of M photographers are using just one type of three common Leica lenses. 21, 35 or 50. One of the three. Yet, photos are different, but here is something common. It is how people are able to see with Leica.
If it makes sense, used Leica cameras are available more and more (and service is still available, but slow), lenses don't have to be new as well or to be Leica made and Leica price range at all.
I would just take M240 (it does have some video functionalities) and one, two lenses. 35 and 50, to see which one works best for your vision. Some people going wider. Many using nothing but 35 or 50. It doesn't limit creativity, but stimulates it, once you know where is your spot.
