Although Leitz >is certainly a trendsetter. Carl, I have the Contax SLR 35mm f/1.4, which also has aspherical elements. The front element has a perfectly flat front surface, which I always thought was pretty interesting. Don't some of the variations of the Leica M 28mm have either flat or concave front surfaces? - - Paul
