Lovely, Erik. The picture and the girl. And one of my favorite lenses; I need to get off my recent Pentax fling and give my Summilux an outing soon.
I'm glad to see this thread take life again; it has made me realize how many lenses Mandler designed lenses I have, and how much I like them. His brilliance was in the compromises he made, leaving a legacy of unique lenses. The 6 element 35 Summicron with its distinctive contrast, and the fabulous 50 Summilux where he delivered amazing 1.4 performance in exchange for curvature of field.
