6. Distortion

The tested lens deals with a negligible level of pincushion distortion. On the APS-C sensor it reaches +0.24% and then it increases to +0.57% when you progress to full frame. It is a better result than that of the Canon 135L but weaker than that of the Samyang 2/135 and the Zeiss Apo Sonnar 2/135. Still you should remember all those values are so low that the distortion won’t be bothersome at all in real life.
