Nikon Nikkor AF-S DX 18-135 mm f/3.5-5.6G ED-IF

6. Distortion

The Nikkor 18-70 mm had poor results only at wide angle, which reached a value of -4.5%. For other focal lengths, distortion was miniature and was never higher than 0.09%.

We, again don't have good news for interested customers. At 18 mm focal length the results for the Nikkor 18-135 mm are the same as for its predecessor. We measured the barrel distortion at -4.6%.

When changing focal length the defect immediately becomes pincushion distortion and reaches a level of 2.4%. Unfortunately, it does not drop - but stays steadily at the same level. At 50 mm it is 2.6%, at 85 mm - 2.2% and at 135 mm it is still 2.0%.

Maybe the level is not extremely high, but it is still visible, as can be seen in the pictures below.
