LEITZ CANADA Leica Summicron 90mm f/2 Second Generation. Serial number: 2151352 This item is in good condition. There are minor scratches on the exterior and some dust inside the lens, but these do not affect the actual images. Sample photos are attached. The sample photos were taken with a digital camera using a mount adapter. No adjustments other than exposure were made during development. The lens cap, hood extension, aperture ring operation, and focus ring operation are all smooth. Since there is no M-mount option in the size selection, Nikon F was selected. No returns or claims accepted.
