Sigma 180 mm f/3.5 EX DG HSM Macro APO
6. Distortion
In the case of a 180 mm fix-focal lens it would be difficult to expect a serious slip-up with frame edge deformations. In fact, the level of distortions is negligible and its value, measured by us, amounted to just 0.16% with 0.1% margin of error. From the statistical point of view you can hardly speak of any problems in this category.
