Famous Konica Hexanon AR 28mm f3.5 lens

This is a very good lens with a retrofocus design of 7 elements in 7 groups, often called a "Japanese Angenieux." I am selling it to clear out my collection.
Rare genuine front and rear caps are included.
This lens is a Konica AR mount, but I am listing it in the Nikon F mount category because there is no category for it.

[Appearance]

There is some minor paint wear from use, but there are almost no major scratches and it is in good condition. Please refer to the images.

[Optics]
There is a very slight amount of dust that does not affect the image. The optics are clear to the naked eye. Upon close inspection, there are faint cleaning marks on the front element, but these are also negligible.
There are also faint cleaning marks on the rear element.
There is no mold or clouding. There is no oil on the aperture blades.

[Operation]

The aperture operates normally.
The focusing helix feels a little stiff, but it is not difficult to operate.

[Included Items]
・Front cap (genuine)
・Rear cap (genuine)
