Why spend money on a Leica when you can get a cheaper Lumix and get the same results.
Or buy my Mamiya 645 kit with enlarger and get better results
That's the bottom end of the scale at Leica.
The V-Lux and D-Lux are indeed rebadged - and more expensive - Panasonics (but with a free licence for Adobe Lightroom as a perk).
From there, it's a quantum leap to the M (full-frame 35 mm sensor) and the S (medium format SLR), where you a looking at prices of 6,000 (M) to between 10,000 and 18,000 or so (S).
