This is a very rare lens. Full details of the lens: http://www.photosynthesis.co.nz/nikon/f5814.html
Marked ‘Lens Made in Japan’ and ‘Pat Pending’. It has a ‘Type 2’ aperture ring, with a 1mm extension. It has 6 aperture blades. Lip on the filter ring.
Included (might not be in photographs): A pair of caps.
Cosmetic: Very lightly used. Black paint is very, very lightly marked on the leading edge of the focusing ring, likely from storage in a soft case. Paint otherwise still has its slightly satin finish suggesting very little use.
Optical: Optics are excellent and unmarked.
Mechanical: Fully working. Focusing is smooth and aperture control is working as it should.
Dust/Haze: A couple of small specs of dust or debris inside. Too small to affect the image.
Graded: Like New Minus
(Close inspection reveals slight signs of wear. )
