This 35-70mm f/3.5 AI was Nikon's first professional midrange zoom from 1977. It is very sharp at every setting and has a constant f/3.5 aperture. It has less distortion than any of Nikon's f/2.8 zooms, and that means much better than the 24-70mm AF-S and 28-70mm AF-S, each of which costs over ten times as much.
Lens works with every manual focus Nikon ever made, from the F of 1959 through the FM3a and today's FM10. On the Df, D4, D3(s,x), D600, D800, D7000, 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 (see original pictures), no scratches on lenses, no fungus, no oil on aperture. Focus runs smooth. Very sharp lens. Comes with caps.
