Selling to organize my collection. Elmar 9cm f4 Elmar 90mm Leica M-mount, made in Germany in 1957. This is a medium telephoto lens for Leica. It's compact and easy to carry. M-mount, 39mm filter thread. There are scratches and marks. The focusing and aperture rings operate smoothly. Please consider this as-is. The buyer should have it serviced if necessary. Please refrain from purchasing if you are overly concerned about condition.
