The Nikon Micro-NIKKOR 105mm f/4 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.
On AF and digital cameras, their finder screens are optimized for lenses like this 105mm f/4, so with modern cameras, this old lens works just great! In fact, with the electronic focus assist on FX cameras, this lens works much better today than it ever did on film.
Lens works with every manual focus Nikon ever made, from the F of 1959 through the FM3a and today's FM10. On the D3(s,x), D3000, D700, D300, D200, and D2 use the "Non-CPU Lens Data" menu option to get full color matrix metering, EXIF data and finder read-out of set aperture. It works great in aperture-preferred as well as manual modes on these cameras. The meters of cheaper digital (D90, D5000 and below) will not couple (or work at all) with this lens, so you have to meter manually.
This classical lens is in very good condition with very small marks in paint (see original pictures), no scratches on lenses, no fungus, no oil on aperture. Focus runs smooth. Very sharp lens. Comes with caps.
