I'm pretty aligned with others here. I'd guess the RX1 is my top choice in these. Just giving my top 3's:
1. Bokeh at 0.6 meters: 5, 1, 4
2. Bokeh/background at 1.2 meters: 5, 3, 1
3. Flare: 4, 3, 1
4. Bokeh and transition at f2 at 10-12 feet: 5, 1, 4
5. F8: Any
6. Grass transition: 3, 6, 1
Thanks for doing this kind of thing, it's very interesting. I remember seeing the last one and being impressed comparing the RX1's f2 image even to f1.4 on others, that lens is special.
