Wonderful stuff! Don't get complacent though, Zeiss has that "variable phase" (VAR-EL??) that you guys don't have. It's a very cool microscope feature. I've always wondered about titanium making more durable cameras. For me durbaility is not measured in how long the finsih lasts, but in how well the camera will suvive on a catastrophic impact, like being dropped on a floor. Correct me if I am wrong, but an increase in Rockwell hardness also increases the likelyhood of shattering, right. Also, softer surfaces absorb impact engergies, as those dents on my Nikon F prism will atttest. With a hard camera covering, will not the energy of an impact be therefore absorbed by the internal camera components, which would be a very bad thing.

Despite all of the off topic discussions and more than sufficient bickering. Time to step up and make a small contribution. By way of introduction, I am an executive with Leica, though not with the Camera group. Essentially, I am Roger Horn's equivalent for the North American surgical microscopy business, headquartered in New Jersey, a couple of miles from the Camera group's offices. I have been a Leica user for many years, since my days (more than 25 years ago) at the University of Missouri, one of our country's better (at least at that time) photojournalism schools. I have pretty good "wiring" into the US camera group (had lunch with Roger last week), and I certainly have some insight into the workings of Leica as a company. Of course, my employment does not make me an authority, and anything you ever hear me say in this forum is my own opinion. Nevertheless, my opinions may from time to time bring a different perspective. As a final intro, I own M6s and M2s, have tried every (current) lens there is and settled on 24, 35 (1.4), 50 (1.4), 50 (2.8) and 90 (2.0). All for B&W available light. My reason to finally jump in has to do with a great deal of misinformation concerning the titanium finish. The titanium finish is not "paint". It is also not a coating or an anodization of the same type as the chrome or black finishes. It is actually something very different. I won't go into the technical stuff, but essentially it is a process by which titanium ions are bombarded (at extremely high speed and at extremely low pressure) and impregnated into the first 3-5 microns of the surface of the substrate. Rather than sitting on the surface of the metal, it actually becomes part of the substrate metal. For this reason, it cannot wear off, and it gives the base material a substantially higher Rockwell hardness. (Anyone interested in this technolog y can find acres of information by searching the web for "titanium coating") It is interesting to note that not all metals can be effectively "coated", including nickel. This is the reason that there is no titanium TTL. All titanium M6s have brass tops. I have a lot of experience with this process/finish from a prior career life. One common demonstration we used to do was to ask the customer to try and scratch it with their keys. Couldn't be done (but I haven't tried this test on my Leica!). You also may have experience with this finish, if you have ever bought titanium coated saw blades or drill bits at your hardware store. (Tool applications have a different finish than the M6's, as the process in that case is optimized for hardness rather than appearance.) Ask the tool expert in your hardware store how durable this finish is. Bottom line. I doubt in future years you will ever see a titanium body or lens with surface wear. (For those of you who actually like brassing, sorry to disappoint you.) This finish is rugged. Personally. I also think that it is the best looking finish Leica makes, as well. You have to see it personally. Do not judge this by the pictures in the brochure, which look too gold. It's actual appearance is closer to a graphite gray than gold. As for the leather, it IS real leather, it is just the "emu" texture rather than real emu. The real bottom line. The titanium finish M6 is still a current product, so you can still get one. It is not in high demand, probably from a lack of proper information (some of which seems to be coming from here). You can use it as your primary body, and still have a collector's item in 20 years.
