Take a deep breath and buy the NEX-C3. Mine's shot 10k faultless images since October last year and I'm just about to order an NEX-7 to partner it.
Initially, I used the two kit lenses, principally the zoom, which is OK if all else fails. The pancake 16mm is soft and wouldn't be in my bag if it weren't so light.
Instead, I bought an E mount/Leica adaptor and hauled two forty year old lenses out of the cupboard; the venerable 50mm Elmar (collapsible) and a 35mm f2 Summicron. The latter has accounted for about 95% of those 10k shots. It is small, easy to use and produces jaw-dropping results. Many of my recent TOP posts have been shot with one of these lenses.
Recently, I bought a Zeiss 25mm f2.8 Biogon and while you'd think it would be easy to use, it has been testing my abilities quite hard. I'm beginning to master it and the results are worth all the effort. It's at least as good as the Summicron, possibly better in some ways. Expensive glass, but remember that lenses like these don't go out of date...
