On the common focal range with the X-10, the zoom X-S1 is hardly less bright (the gap is about 1 IL).
The image quality is slightly lower in the corners at full aperture, but it is seen as 100% on the big screen, and it should be unnoticeable in prints up to A4 or even A3.
I think the negative comments of some journals can be explained by the fact that the maximum magnification replay rear screen goes beyond 100%. 100% on the computer screen, all my shots are satisfactory.
The electronic viewfinder is excellent.
Overall ergonomics is very close to an SLR.
I long to tame the various specific possibilities of the X10, but it allows me to quickly master the X-S1.
I highly recommend users to explore the various automatic modes EXR, using the specificity of the Fuji sensor for improved dynamics, color rendition and noise processing. While this leads to 6-megapixel JPEG instead of 12, but in practice the images are almost as detailed and perceived quality to the eye much closer to that of an APS-C DSLR.
It is unfortunate that the user guide is so little detail about these specific features to these Fuji cameras. I almost took a year to understand their exceptional interest.
The EXR Auto mode allows you to forget the settings, the device deciding alone. Note however that the autofocus in cases where the choice of the main subject is not obvious.
For my part, I assigned each of three EXR Priority modes with 3 programmable user modes of the wheel: it allows me to choose between myself prioritize dynamic range, reduced noise in high ISO or definition maximum of 12 MP.
So I keep the EXR setting for direct access to EXR car, which in my opinion gives better results than any self any conventional auto mode.
Compared with my APS-C DSLR with 18-135 zoom (equivalent to 27-202 FF), the weight and dimensions are comparable, but the versatility of superzoom is a huge advantage for all cases where we do not expand the beyond A4 size.
The super wide-angle 24 mm is very well corrected JPEG.
The APS-C is of course much more efficient in low light, where the large sensor 6400 are at par or better than the ISO 1600 on the X-S1 for landscapes enlargements A2 or beyond where relevant 16MP (provided you have good optical) and the subtlety of colors and dynamic range of high-contrast scenes. But we are on budgets 3-10 times higher.
And video mode X-S1 is really exploitable through the electronic viewfinder, which is not the case where only the DSLR live view is usable.
In conclusion, I highly recommend this unit to anyone who wants a very versatile zoom with image quality and shooting comfort close to an APS-C DSLR.
