I think Leica uses this for subjecting cameras to maximum and minimum temperature tolerance tests. Using statistical methods, they check a certain number of items coming off the assembly line in a random manner. If those items pass a thorough inspection, they assume that the entire batch is acceptable. <snip> When I visited Leica Solms in 1995, my tour guide (please forgive me, I have forgotten his name) stated quite clearly that Leica tested EVERY camera before it could be shipped out of the factory. They did not use statistical sampling. The Leica tour guide told me of a visitor from IBM couldn't believe Leica tested each camera. Leica literature even states that they make negatives with every lens that is produced and even keep the negatives on file for future comparison. Solms must have some very big file cabinets. It would be nice if someone from Leica would simply respond with an email for the group to let us know they hear our concerns. If anything, its good public relations. Kind of makes you feel better when you know someone has heard your comments. I mean no disrespect but up until now, you'd think Leica was deaf, dumb and blind to these issues. Now that I said that, I guess I don't get a free 15mm R lens for my R8. <bg> My kids are getting real skinny without any food for 2 weeks now...
