While this is all very good and interesting, it raises the issue of relevance. You've had your M6 for 17 years. Let's assume that you put 200 rolls of film through it in a year, which means that after 3,400 rolls of film (122,400 frame advances) it is still not "broken in". Personally, I'd be much more concerned with whether my M6 felt smooth, efficient, and broken in *during* those 122,400 frames than whether it would last another 1,000,000 afterwards. I'd even be willing to pay $400 in repair costs for new brass gears, say, every 10 years if I could have that buttery smooth feeling of an M3 in my M6. I venture a guess that most Leica rangefinder owners do not shoot 200 rolls of film a year, many perhaps not even shooting 3,400 rolls of film in their lifetime. The point then becomes, *why* it is necessary to have gears that last 1,000,000 frame advances at the price of the smoothness and articulation of that action, when few people are going to use it that much? Why not offer steel gears as an option for those who really need it? This goes back to the issue that was raised a few weeks ago -- creeping featurism. I should think that for the vast majority of Leica rangefinder users, the steel gears is a moot point. Sure, engineering excellence, but at the expense of quality of use. And isn't that what Leicas are supposed to be all about? M. - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
