ArtKetchum: The new Leica Lens module will put the Ricoh GXR camera on the map. A great idea and Ricoh being the first to offer Leica compatibility will make the GXR a very desirable camera.
I am glad you are happy using your CV 40 lens on your 4/3. I don't see how it addresses my point.. Leica has a full range of full frame lenses which would become quit useless on a high crop system. I have the M8 (1.3x) and find it extremely limiting. Leica lenses, and in general, rangefinder lenses were made with an emphasize on particular focal ranges, mainly fast 28-35 extending to 21 on the wide side and 50, 75, 90 on the short, stretching up to 135. the classical fast 28-35, which were always the heart of the system, simply have no parallel when used on a x2. Fuji, Ricoh and Sony are smart to introcude fast 24 lenses (actually, Ricoh goes wider). Nevertheless, they cannot reach the traditional depth of field of the desired focal lenses. That's a compromise I can understand. I cannot imagine anybody buying a 3000$ FF lens to use on a x2.
But it is not that Leica is in any lack of short to medium teles. such as the 75lux (which I own, and like much more than my canon 85L 1.2, for example) or any 90 lens, which Leica is so good at making. The problem is the lack of fast wides. The only "solution" is the 21lux, which is a 6000$ lens. Obviously, if anybody is planning to buy a body to use with M mount lenses, any crop is a disadvantage, not an advantage.
but even a 1.5 crop is too much for many (I have the M8 which has 1.3x and I certainly cannot afford the M9). x2 as with 4/3 is really useless. and I do have 7 Leica lenses from 21 up to 135. the fastest wide I have is the 28 which is a short tele on the 4/3. that's not what Leica was made for... the Ricoh is very tempting and beautifully crafted camera. Nevertheless, I will probably wait for the Nex7 but I haven't decided yet.
