And I do not believe that books by Leica PR people are much different. But there actually might be a period when they really tried this because there are some really bad Summicron 50 test results from the ´seventies - lack of resolution and lack of contrast. All the best!

I am holding in my hand a glossy information booklet entitled "Leica Lenses" published by Ernst Leitz GMBH Wetzlar/West Germany in 1969 (ref. no. VII/69/CY/Mi). In a chapter titled "Resolving and Contrast" the authors claim that the concepts of resolving power and contrast are not necessarily linked and offer photographic evidence that of the two, high contrast is more important for general photography. The booklet was given to me by a Leica factory rep. in 1970 as an explanation of why Leica redesigned its lenses to emphasise contrast. Erwin, this is not mythology. It is Leica's own history. Science is another matter. Larry Zeitlin
