Benjamin, that little Pana is so sweet! I really want one. How do you like the optical viewfinder? Is it worth it?
On the DSLR subject, I agree with Dirk on the glass point, with one caveat. Between Nikon and Canon, I don't think you can go wrong with either system, and they both offer full-frame bodies. For many, I think Canon may have an advantage on this front just because a 5D can be picked up used for a pretty good price. I really see a big difference sometimes with the 5D; there is an artistic quality to some images that my 30D lacks. It is hard to describe, but it reminds me of photos from my old FM2; the images have a depth and texture to them very much like film.
