The RX1 may have some (very mild in my opinion) issues, but they only seem to be visible in very specific situations (evenly lit white walls and such...), and they don´t tend to show much in normal life shooting and situations. The majority of the new owners (even the ones that are aware of this issues) don´t seem to be willing to part with the camera and are quite satisfied with it.
I have owned a bunch of cameras along the years ,compacts, DSLR´s -APS and Fullframe-, micro 4/3, Fuji X100 and now Nex 7 (which is currently my only camera). I have been been fairly happy with all my cameras, none of them was without issues and limitations, I learned to live with them and enjoy them. I believe that as a "capturing-beautiful-memories-and-images-of-real-life-and-the-years-passing-by" kind of machine the RX1 is going to be quite a success.
There is a very small and select club of cameras that hold a special place in the collective memory of the photography community. In the times of film, an example of such cameras could be the Fuji GW series of cameras (specially the 6x9 models that seem to hold their value forever), and the Konica Hexar 35 AF which is very sought after and has been in business producing stunning images for years and years. In the digital era, the Leica Digilux2 inmediately comes to mind: this camera seems to have a "je ne sais quoi" and certainly holds a very special status (and it´s value) among photographers. Another such camera is the original 5D, which even when it can be found for peanuts now, certainly took the world by storm when it appeared and will remain forever as a milestone. I have a feeling the RX1 is bound to join this little lovely club..
I for one won´t be purchasing this camera for a number of reasons, but I really like the images that I´m seeing coming out of this camera, it has in my opinion (OK, OK, I´ve only seen web JPEGS, I know) a beautiful way or "drawing" that I haven´t seen for example with the Nex6/7 and the Sonnar 24/1.8 which is regarded as the best in the Nex lineup and is also a Zeiss lens. But I can see a compact full frame mirror-less interchangeable camera (Nex or not) in my future, I think the RX1 is a step in the right direction.. My 2c.
Good light!!
