Nikon Nikkor AF 80-200 mm f/2.8D ED

8. Vignetting

Therefore at the 80 mm focal length at f/2.8 the vignetting is 14% (-0.43 the value of the diaphragm) and it drops rapidly when stopped to f/4. At 135 mm focal length the situation is even better since the light fall off in the corners of the frame at the maximum aperture is only 11% (-0.34 the value of the frame) and at f/4 it is only 2%.

The largest chances of seeing vignetting are at 200 mm focal length and with an f/2.8 diaphragm. The light fall off in this case is 21% (-0.68 value of the frame). But we won’t see it any more since the defect drops to 11% at f/4.0 and then drops even further to 2% at f/5.6.

These results are just minimally better than the Sigma’s 70-200 f/2.8 results, which with the maximum aperture at the 70, 13 and 200 mm focal lengths, had a light fall off of 12%, 14% and 23%, respectively.
