I also have the S007 with 4 lenses but I am trying to sell that gear as the IQ of the H6D100c is just so much better. I will take my H6D100c 50, 100 and 150mm and leave the 300mm at homeWhen I started to use my S-system I used it for all kinds including family, travel etc.
What I usually do is bring maybe 4 lenses on the trip but only 2 max. 3 on a hike, so some lenses stay in the room. I think one of the big good things about the S is that it is not that much bigger than a DSLR. The x1d is even better (in regards of size). I dont know if I wanted to schlepp around a big Hassy or phase.
With the L-mount cameras I sometimes prefer the flexibility of the zooms - for example the 16-35 or the 24-90 or the Telezoom, and also the SL primes are exceptional. I feel the IQ gap is not as big as it was 6 years ago.
Lately I have used the S more often again. I do not only like the IQ but also the solid feel , simple user interface and optical viewfinder.
