This Zeiss 40mm f4.5 Luminar Macro Lens, #4088643, is in great condition with minor handling wear. I rate it cosmetically a (9+). The aperture ring is quite 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 3.5:1 to 12:1. It includes the original case, the top of which functions as a threaded rear cap. Please refer to the photos for details.
