Thanks for the great feedback all. Let me just pick up on some specific points, if I may.
@Amin - Your "great" and "good" for your M240 are pretty well all the things I love about my film Ms. Interestingly, your "bad" and "terrible" are, to me at least, endemic to the digital Ms... I too went Nikon DSLR (D700) before I went to Fuji - I had my remaining R lenses Leitaxed, and they performed extremely well with the FF sensor. But it isn't a rangefinder...
@Iansky - it sounds like you and I are on very similar trajectories, for very similar reasons, even down to the GR and the Barnack. I think it is an appreciation of quality - both build- and output- in a small package. The Barnacks are jewel-like, and even if my M2 goes in time, I can see myself hanging on to my IID for many years to come. You don't own the battery-independent, film Leicas, you curate them for a while, exercise them and give them purpose, before passing them on.
@grillec - I respectfully disagree; this IS a Leica thing. Only Leica has the heritage, the past history of innovation, the personalities, the twists and turns in their story, the uncompromising approach to quality, the ethos... need I go on? I have lived and breathed Leica for more than two decades. In that same time I have owned cameras and lenses from Nikon, Pentax, Contax, Rollei, Olympus, Panasonic, Ricoh, Fuji, Minox - none have the same emotional impact as a Barnack or a film M. The company - not the brand - delights with one hand and frustrates on the other, like an inappropriate love affair.
@Dalethorn - Ref. the X-Vario. No. Just ...no. It is a kludge that is likely to have one of the shortest-lived production runs of any Leica of modern times. The current prices are low for a reason. It is a shadow, a shade, a pastiche, a caricature of what a Leica should be - a mediocre lens in an M-lite body, with buggy firmware and a clip-on EVF... let me say that again - a clip-on EVF... If I was given one as a present I would give it away - honestly. It represents in concept and execution all that is wrong with the current Leica lineup - even more than the T, which at least tries to strike out in a new direction.
