I have just received a Kippon adapter that allows me to fit my Nikon primes to my Sony NEX 5N. I have the 24mm f2.8, 35mm f2, 50mm f1.4 and 135mm f2 DC lenses, all with aperture rings. As a first draft test, I did some comparisons of the NEX 5N with the Nikon 24mm f2,8 against the Fuji X100. The 24mm on the NEX equals 36mm, so its pretty much the same with Fuji X100′s focal length.
These are not of course scientific tests, I just shot the same frames with both cameras just like I was taking ordinary images (I prefer to compare in real life situations, if I find the time I will try to do a better comparison with cameras mounted on tripod etc.)
From all the samples I keeped two pairs of images. The first one is a crop from the original image shot at f5.6
The second example is more representative since the pavement provides a good testing ground especially for sharpness. For this pair of images I did the following post process: Auto Tone, Auto Color and Unsharp Mask using the same parameters for both cameras.

For this pair I preferred not to mention which picture belongs to each camera, but its very easy to see a clear difference here. I think its obvious who is the winner here.
I repeat, I do this tests for me in order to decide which camera or lens is better for my tastes, so don’t take that as a scientific test. What I have noticed is that the NEX 5N with an adapter and my 24mm Nikon lens cannot match the image quality of the Fuji X100. It’s not far away, but the difference is easy to spot. I chose this particular lens because its affordable and this combo is about the same price as the X100. I am sure the e-mount Zeiss 24mm f1.8 or one of my Leica lenses would be a hard contender for the X100 but the price will dramatically increase with these setups.
Nevertheless, the NEX 5N/Nikon 24mm f2.8 combo makes a great street setup for the NEX (manual focus of course but this is something I am used to !!)
