Summary: I am inclined to agree with reviewer RT about the V-Lux 20. I too own the D-Lux 4, and also a Nikon D3S. I was looking for something of Leica quality, but with the added reach of the extra zoom lens.
Summary: First let me start by saying I have never bought a digital camera that did not come with a memory card.(this is my 3rd). This $699 camera did not. I called Willoubhy's and they said I would have to buy one. So I bought an 8GB card for $42. It works fine for still pictiues but not for video.
Summary: Four years down the line I have just bought one on e-bay for £50. Not bad seeing that Leica charge£70 for a spare battery. They say in the 165 pages of instruction sheets that a non-leica battery might cause the camera to explode?
