A Ricoh GXR body with a Voigtlander 35mm f2.5 color skopar lens attached on an A12 Leica M module.
If there's anything worth saying about the Ricoh GXR it will be the point that it changed the way photography was known as a by product of the fusion of a camera body and a lens. While it is true that the digital age seemed to have completely changed everything by allowing us to forget about spending on endless spools of films in exchange for plugging in memory cards on our camera to store the pictures we have taken, the same classic approach of screwing in a camera lens on the appropriate camera body has been carried on at the moment of this writing so that the recurring issue of the camera's sensor being 'unconsciously' exposed to dust particles each time a lens is being removed and reattached is the ever existing nightmare for most photographers.
Ricoh's approach to the problem by housing a separate sensor on a Ricoh GXR lens module means that there are no issues of dust to worry about ruining your pictures except if you are using the A12 Leica M module where you are screwing in the lens on the module just like on a digital SLR.
First announced in November 2009, the Ricoh GXR remains a revolutionary approach to photography and with its mirrorless APS-C sized sensor you have a compact, photography tool that even allows you a cheaper approach if you can't afford any Leica camera body by trying any cheapest Leica lens you can get hold of through the A12 module designed to accept Leica M mount lenses as in the above picture.
