According to J. Eastlands Leica M Compendium there a two version of this lens, a 7 and a 6 elements design. Does any of you know what kind of lens mine is? Serial number is 2518961. This book also states the differences this specimen and the current optical design so minute as to be of little consequence. Is this true? Erwin what are your findings? ========= Bert Keuken
