Introduced back in 1986 the Nikkor AF 70-210mm f/4 was the first AF tele-zoom
lens introduced by Nikon. The constant aperture is an attractive feature
of the lens but for whatever reason this affordable Nikkor was only manufactured
for a few years so you will only find it on the used market these days.
Surprisingly Nikon did not release any new constant f/4 tele zoom lenses in
this range ever since which is regrettable regarding the very popular Canon
options in this class.
Regarding its age it is, naturally, a full format lens. All local
Nikon tests are performed on an APS-C DSLR where its field-of-view is
equivalent to 105-315mm on full format camera.
On first contact the build quality is feels good thanks to quality plastics.
The very broad zoom ring operates very smooth. However, the tiny focus ring
located directly on the inner lens tube is a little substandard. The physical
length of the lens does not change during zooming but the inner tube
extends/retracts a little when focusing (see also the product shots above). Unfortunately
the front element rotates so using a polarizer is quite cumbersome.
The Nikkor has a rather long focus path which is nice for manual focusing.
On the downside the AF (via the slotted drive screw operated by the camera) is
slow and noisy. The AF accuracy was a little soso in field conditions with slight
tendency to front-focusing at the long end of the zoom range.
