I have also updated my Conclusions page discussing my hypothesis about the pixel-level sharpness of the X-Pro1.
After studying dozens of images, something “clicked” for me in looking at the images, something I’ve seen before with Nikon Capture NX2 sharpening, and I think that the odds are very good for seeing a boost in the micro contrast and fine detail when Adobe Camera RAW (ACR) offers support for the X-Pro1. Using its form of deconvolution sharpening. In short, I think that the SilkyPix RAW converter is doing a poor job at extracting the detail that is latent in the X-Pro1 RAW files.
In terms of sensor quality, the X-Pro1 sensor at ISO 200 seems to be superior to the Canon 5D Mark III at ISO 100, in tonality and low noise. The X-Pro1 is very impressive in that regard.
