Why Leica M3 ?
Here you can see an Elmar 5cm F3.5 lens which was made in 1933 and had been continued in the same configuration almost thirty years as a Leica standard lens. It is possible to take photos using it on the current version of the Leica M6. It still gets a sharp image. Most of the old Leitz lenses are able to be used as interchangeable lenses on M series Leica.
An unique serial number has been put on the body from the beginning and strictly filed as a chronological table. You are able to know that when your camera was made or what type of camera you've got from the table.
