My copy I wouldn't describe as being "very" sharp wide open, but it is certainly as sharp as any other fast 35 I have tried, except the Leica 35 Summilux-R in the centre. Perhaps this is because you are using a D700, and I am using a D800...
I'm really not judging sharpness at a pixel level, so I don't think it matters much. If I scale the RX1 shot down to 12 mpix they are about equal at f/2.
In this example, I prefer the look of the ZF, but the RX is very close, and the exposure is better. For visually equal exposures, I would probably prefer the ZF even more.
Yeah, the blown highlights doesn't matter and the RX1 should be pushed a bit more. I think it would look more pleasing overall just by being brighter. Though, I like the colors from the D700 better. Look at the wooden thing on the right for example.
When your fever is gone and your fingertips are too painful to use your Gibson, I would be interested in seeing boke samples wide open or f/2 at maybe 3-5 and 5-10m, if you feel like it.
Unfortunately my apartment is very small, so if there should be any distant background to blur, I'll have to go outside. And its pretty cold today!
