That said, of Fuji\'s samples so far, I feel those from the 18mm are the weakest. The trees along the horizon of the night shot just aren\'t sharply rendered compared to what I know the CV15 or ZM18 could offer..
That shot of the trees is weak and I have seen much better even from my X100. Just looking at the exp. info might even explain part of it though. F10 at 1.9 sec. F10 is definitely not going to be the sharpest F stop due to diffraction on this smaller format. F4/5.6 should be the sharpest with F8 still decent. There also could have been wind or movement at 1.9 seconds.
Regarding wide rangefinder lenses and the XP1, it will likely be just as good as the Ricoh since it has no AA filter, and thus better then any current NEX, but it\'s probably not going to be perfect. The only reason I say this is that Fuji makes a point (in the XPro1 dedicated site) about designing their wide lens for the camera with a very large rear element in order to reduce the angle of incidence. Thus, I would expect ultra wides with large rear elements to do well...but how many fit into that category?
Yes, there are a number of possible variables that could degrade image quality. But to me it doesn\'t just look like diffraction softness. Towards the left corner the image seems a bit smeared. Fuji actually has some rudimentary MTF curves for each lens here: http://fujifilm-x.com/x-pro1/en/about/lens/index.html though I think they\'ve mislabeled each, as the 15 lpm is probably the one labeled 45 lpm and vice versa. They also don\'t indicate the f/stop. If the graphs are for a stopped down lens, then it might explain what we\'re seeing in the sample photo. The other 18mm image of the yellow building also loses a bit into the top corners, but this one was at f/5.6 and might be on the edge of acceptable depth of field depending on the focusing distance.

The second sample appears a lot better (Although I found all samples to be a tad soft).
