6. Distortion

While using JPEG files it would be difficult to notice any traces of distortion – in that case our measurements showed just negligent barrel deformations amounting to −0.30%. When you pass to RAW files the situation changes a bit. This time the distortion level reaches −1.10%. It is not a high value but with such an angle of view you should expect a tad lower results.
