It is a substantial operation, more than a 1000 employees and one of the last camera-manufacturers to make their own glass (more on that later). We all trooped in to a meeting room and the fun began! Prototypes of coming products were brought in, lenses, bodies and accessories. I had already seen and tried the 28/1,9 Asph and the 90/3,5 Apo-Lanthar at Photokina so that was old news and nobody even bothered to bring these in! Instead, there were new lenses and different mounts on lenses. Most of this stuff is still cloaked in secrecy so I cannot tell anything. But there are a couple of pieces that can be revealed, a small, compact 39mm screw-mount lens that fills the gap between the 15 and 25, the 125/2,8 Apo-Lanthar Macro for Nikon-F and in other mounts, as well as the 75/2,5 in Nikon mount. The difference between talking to some other manufacturer and Cosina is evident in the following exchange. I was playing with the 125/2,5 Apo-Lanthar and I asked Mr Kobayashi "Would it be possible to make this lens in a Visoflex-mount?" His response was instant "Should it be a pre-set aperture or a regular one" rather than the "why would one bother" that some other manufacturers would respond! If anyone thought that Voigtlander/Cosina is through with ideas for Leica's, just wait and see. The other difference is that when Shintaro and I wanted to look inside a camera, a toolkit was brought so we could take the thing apart and see how it was done. Anyone who knows Shintaro also knows that this is how he functions. Only lack of time prohibited him from redesigning the commuter-train seats! The fact that we could pass on suggestions for improvements where meet with "Yes, that is a better idea" or "Right on!" By this time lunchtime had arrived and we set out for a sushi-lunch (I am not too clumsy with chopsticks. Shintaro's family dog, EDO is devoted to me though, he knows that the "gaijin" is highly likely to drop nice tidbits and usually spends dinners firmly pressed against my leg). After lunch, we were shown the assembly area (Bessa-R and L) as well as the optical plant with rather impressive vacuum chambers for coating lenses. I looked at the assembly of the finder for the 12mm lens. It is no wonder that this finder is so good, it has multiple elements in it, including aspherical surface ones! My favourite machine was the Computer controlled milling and turning center for making screw-to M bayonet adapters. Now this is a machine we all could relate to. Who needs a printing press for money when you could be turning out nice adapters like that! The glass making area was the only area we were told not to take pictures in; otherwise it was fine everywhere else. I have been to glass-plants before and they are fascinating. It has to be a mixture of alchemy and science! Measured quantities of raw material, with cryptic notes on the bags, are poured into the furnaces and once the glass-mass is molten it is "squeezed" out on a conveyor belt, glowing red and "plastic" in its consistency. The conveyor slowly (you can't really see it move) transports the endless strip of glass through the cooling chambers and at the other end it looks like clear, oversized chocolate bar. The glass is cut in to manageable chunks (about 18-24" long, about 1" thick and 4" wide). These bars are stacked and then later cut into pieces that are reformed in gas-fired furnaces as "blanks". Once this is achieved, the pieces are ground and coated. Of course, each type of glass requires its own formula and process, but it must be a major advantage to have a production facility "in house" for experiments and also for scheduling productions. Now, this would be rather nice to have at home. Imagine coming up with a design, being able to make a prototype, including aspherical surfaces and rare glasses, try it out and say "This works, let's make it"! It is rather fun to see what a camera-buff and active photographer can get done when he has the facilities and expertise to implement his ideas. Of course Cosina makes a multitude of products, Nikon FM-10/Olympus 2000 etc, as well as a large variety of optics for Canon etc as well as beam-splitters for video-cameras etc. However, the Voigtlander part of the operation accounts for over 10% of the production. This has all happened in less than 24 months and the flow of ideas seem to be on the increase, rather than tapering off. Products from Voigtlander, Ricoh, Konica, Kobalux, Minolta, and Pentax are now available in 39mm screw-mount (and M-mount in the case of Konica). Some are design exercises, such as the 43mm Pentax lens with a nice, but big finder and a price-tag of US$1300 or the 60 and 50 mm 1,2 lenses from Konica, but the rest are highly useful and extremely high quality optics. There have never been more choices for an M or LTM user in Leicas history. All right, I know that one really only needs a 35/2 and a 50/2 with a M2 and a M3 to take great pictures, but deep inside most photographers lurks a "gear-head" that enjoys optics and mechanical contraptions.
