The AF 80-200mm f/2.8D ED has a very moderate zoom ratio and the level of
distortion is pretty moderate accordingly. At 80mm there is marginal
barrel distortion (0.35%) changing to moderate pincushion distortion
at 200mm (0.77%).
The chart above has a real-world size of about 120x80cm.
On full format SLRs the AF 80-200mm f/2.8D ED has a rather mediocre reputation
regarding vignetting especially at the 200mm setting. However, on an APS-C
DSLR the lens can take advantage of a sweet spot effect. The issue is very well
controlled here and not overly field relevant even at wide-open aperture.
In the MTF lab the lens was able to produce some quite impressive resolution
figures. However, the tested sample also exhibited a slight centering defect
which may have polluted the data a little bit. I had to reduce the number
of measurement points to get meaningful values.
The center resolution is the lens is great throughout the zoom range. At 80mm
it even scratches the resolution limits of the D200 sensor at f/5.6. The
border performance is slightly lower (but still very good) at wide-open
aperture but it improves gradually towards medium aperture settings.
Below is a simplified summary of the formal findings. The chart shows line widths
per picture height (LW/PH) which can be taken as a measure for sharpness.

Chromatic Aberrations (CAs)
Chromatic aberrations (color shadows at harsh contrast transitions) are
relatively well controlled but they can reach 1px on the average at
the image borders at the extreme ends of the zoom range.
Despite its age the Nikkor AF 80-200mm f/2.8D ED is a great lens both mechanically
as well as optically (assuming you can get a good sample). The resolution
is on a very high level throughout the zoom range and neither distortions nor
vignetting are big issues (on an APS-C DSLR). CAs can be visible at times but
the problem isn't overly pronounced. It is a joy to use this lens and the relatively
large aperture provides some creative potential in the convenient package
of a zoom. The comparatively low price tag is also a good
argument to have a deeper look into this interesting option ... unless, of course,
you can afford the AF-S 70-200mm f/2.8G IF-ED VR.
