Overview

The Nikon AF Nikkor 70-210mm f/4 is a constant-aperture telephoto zoom from 1986, offering solid build with a metal filter ring and a seven-blade diaphragm. Optically, it delivers excellent resolution at 70mm but softness at 135mm and 210mm wide open, with significant vignetting at the long end and longitudinal chromatic aberrations. Distortion is low, but purple fringing can occur in high contrast. Autofocus is slow and noisy by modern standards. It suits budget-conscious photographers seeking a fast, close-focusing telezoom for static subjects, especially on full-frame cameras.
