I'm not that impressed by the samples. Why?
1) I don't know if they are 1:1 samples, partly because I don't speak french
2) If they are JPEG I don't know how they had been processed
3) It's not obvious to me that the images are better than what I can achieve with my Sony Alpha 900. They may be better but it is not obvious to me.
1) The samples may be great! I'm just not able to judge
2) No reason whatsoever to believe that the S2 images would not be superior, I just don't feel the samples demonstrate this
I my view Leica tries to create a new "class" of camera, essentially an MFDB sized DSLR with weather sealing . Pentax tries to do the same at a more reasonable price point. Will Leica succeed? I don't know.
Some people are willing to pay for the ultimate edge in image quality. If you make your living printing at large size it actually makes sense. For smaller prints it may just not matter.
I'd say that our host Michael Reichmann is at one end of the spectrum, in search of ultimate quality. James Russel, another frequent poster on this forums, seems to feel that does it matter little for the client what equipment has been used as long as it is good enough. My guess is that if you print large enough, any improvement in image quality is welcome.
Finally, I'd suggest that utility is as important as quality. If you don't have the lens you need, it won't help that the lenses you don't need are as good as they could be.
I've been barking against Leica S2, I would have like them to make a digital successor of the R9 more than this risky and "unfinished" S2.
But I do have a more contrasted opinion after examinating some files from a place that I know in Madrid.
There is also an interesting link in french (use google traductor) with some 100% details from images, well if it is 8bits jpegs for the web,
the IQ is nothing less than exceptional.
If they fix the tethered issues it might really be a serious alternative to Phase and Hassy etc...
