6. Distortion

The C series originally was supposed to consist of lenses that would be a result of a compromise to some extend, the right balance between dimensions, weight, performance and price. Distortion is a field where it is easy to compromise- after all, you can partially correct that aberration with camera software.

The results of our test show that indeed, perfect distortion correction wasn't a priority of the Sigma constructors. On the APS-C sensor you can notice slight barrel variation of −1.04% which increases to a noticeable level of −1.94% when you progress to full frame. As always we have to add that the practice of giving up distortion correction completely is nothing we would applaud.

After all there are lenses that prove that it can be done properly, like the Sony FE 35 mm f/1.8, with distortion corrected by optics so well it amounts to practically zero. Similarly well fares the Batis 2/40 CF although in its case we admit the task is a tad easier because of a slightly narrower field of view.
