This Zeiss 100mm f6.3 Luminar Macro Lens, #4157144, is in great condition with minor handling wear. I rate it cosmetically a (9+). The aperture ring is very stiff, but the aperture functions properly and the glass is clean and clear with no haze, marks, or fungus. There are a few faint specks of dust inside, but they do not affect image quality. It has coverage up to 4x5" and optimized magnification between 0.8x & 8x. The included Synchro-Compur shutter is in similar condition, also rated a (9+). The shutter speed ring is smooth and the shutter is accurate at all speeds. This lens includes a threaded front lens ring, a flared retaining ring, and a Linhof Technika conical lens board. Please refer to the photos for details.
