This classical lens is in very good condition with small signs of use (see original pictures), no scratches on lenses, no fungus, no oil on aperture. But: the focus thread has a small bearing play. Very sharp lens. Comes with caps.
The Nikon Micro-NIKKOR 105mm f/2,8 has excellent optics and mechanics. It is at least 90% as good as today's newest 105mm lenses wide-open, and at least as good stopped down. Unlike the newest lenses, it is manual-focus only, which is ideal for macro work. This f/2.8 lens was introduced in 1983 to replace the slower 105mm f/4 Micro-NIKKOR AI-s. The faster speed makes focusing at macro distances easier on manual-focus cameras. In fact, with the electronic focus assist on FX cameras, this lens works much better today than it ever did on film.
