Franco,
One of my favorite sites for digital cameras rated the R1 very highly for much the same reasons you've stated.
Sony R1
Excerpt: "I'll start as I shall no doubt finish this little piece of editorial, the lens is worth the price of the DSC-R1 alone. That fact is not to be underestimated, it's a great lens which provides you with a very useful 24 – 120 mm zoom range (which will be sufficient for the majority of users). Doing the math it's pretty clear that you have to spend a fairly considerable sum on lenses for a D-SLR to get close to this range and the quality of the DSC-R1's lens."
