Hello Steve,
thanks for this informative review.
I would like to add some comments based on having owned two X100 and lately an X-E1, which I sold when I was delivered the M but used alongside the M9 and MM.
First: noise. It is easy to see that the X100s (or, better, the x-trans 16 mpix sensor) shows little or no noise at 1600 and 3200 iso. But, according to an Italian magazine which put the x-pro 1 to the bench, the nominal vs measured iso values for the x-trans 16 mpix sensor are as follows:
1600 iso = 987 iso measured
3200 iso = 1470 iso measured
6400 iso = 1870 iso measured
According to the above, when the camera is set to, say, 3200 iso, it captures an underexposed 1470 iso shot which is then given back brightness by the in-camera electronics. So, at 3200 iso the sensor delivers “1470 iso noise” (or close to that, given the “curve lift” performed in-camera) and at 3200 iso the sensor delivers “1870 iso noise”. It is still a very good result in terms of “final shot noise”, but it is also true that almost any modern camera is able to deliver noise free 1470 iso photos.
The side effect of the above is the “digital look”, which is the second issue and you mention that as well. The “underexposure + plus curve lifting + nr” performed by the camera at almost any iso level gave my x-e1 pictures an unpleasant digital look which I fully recognise in the x100s samples you posted within your review, with colors often overall “brownish”, not fully realistic and lacking the separation you can find in other camera’s output.
The software lift performed on native files has in my view another side effect: Lightroom in my experience is not properly able to “reverse engineer” the x-e1 files, in the sense that sliders movements have subtly different effects compared to what I would get with other cameras’ files (I use LR since version 1 with all the cameras I own and owned).
Over the last two years I owned two x100, one “first batch” and the other “late”, an x-pro1 for a very limited time and an x-e1 for 5 months. After having reviewed respective image quality, I concluded that the x100 delivered the best files by far and large.
Maybe this new x100s will be better, but if it is anything similar from the x-e1 I believe that for the price of less speed the old x100 is still the better bet.
Best regards,
Mauro

no, a TC

no, a TC
a dire il vero, se Kipon o chi per essi han fatto lo stesso che esiste per nex, si possono usare

ho semplicemente risposto alla domanda, senza altre considerazioni.
in realta' la regolazione manuale del diaframma e' piuttosto imprecisa e non viene trasmessa alcuna funzione automatica.
