The LX2 is noticeably noisier than the D-LUX 3 but slightly less so than the FZ50. The D-LUX 3 exhibits the lowest noise of the four cameras. It leads me to assume that it uses a selected CCD to meet Leica specifications. My tests are on the CCD web pages.
So, if I am correct in my observations, what do you get when you buy the Leica V-LUX 1?
You get a camera that meets the Leica specifications and that is guaranteed not to exceed their tolerance limit. The FZ50 might have a higher tolerance limit on the CCD. If so, you might get one which is noisier than the V-LUX 1. In my case it appears that I tested a FZ50 which is noise-wise below the V-LUX 1 limit.
The D-LUX 3 appears to use a CCD with tighter specifications and if so will provide better image quality in low light portions of a photograph than the LX2. Both cameras use a CCD design that gives a different noise pattern than the CCD in the V-LUX 1 or the FZ50.
These are my conclusions about the camera differences. Since they are based on testing one sample from each model they are statistically speaking not solid. I just wished that Leica would be more forthcoming about what is really going on. Since the company is usually very committed to quality I will assume that this is also reflected in their compact digital cameras, and not just in the M-series. It would be valuable for a potential buyer to know what is special about a D-LUX 3 or a V-LUX 1 and other models that seem to have a lower cost "equivalent". Hopefully it is not only a Leica brand mystique.
