To tell the truth no prime lenses from the range of 70-85 mm, tested here, have had any problems with distortion so far. E.g. a Canon 1.8/85 had a result of –0.10%, a Nikkor with the same parameters – 0.07%, a Sigma 2.8/70 Macro reached 0.08 for a change and a Zeiss Planar 1.4/85 only 0.05%. All these results, in the margin of errors, are tantamount to a complete lack of distortion.

Because of that fact we didn’t expect any problems or unpleasant surprises in this category. Indeed, we were right. The result of the Pentax is 0.06% so practically a zero.
