Carl, I think you got a good one. Definitely a modern lens design....the lack of flare from the window is notable.
I've used a couple of different sample of DX35/1.8G, but none has shown any noticeable sample variation. All in all, I had good experiences, except for the uneven aperture opening shape when stopped down by 1-2 stops.
Carl, if you are not particular about the last point, you should enjoy the lens.
Fons, that is an interesting example. The vignetting should be stronger when focused at distances.
