I had similar ideas swirling around in my head. For a full frame body I decided to
1) not go with a lens that has more than ~400g of weight
2) take a lens that is strong wide open (preferably f2) for dim landscapes and cityscapes
3) Skip zooms since
- these all weigh >400g or
- have an aperture that starts way beyond f2.8 with this weight limit
4) Take a maximum of 3 lenses
