Geometric aberrations at the edge of the frame, in this lens class, have never been a problem. You can remember that Nikkor 80-200 mm f/2.8 showed distortion in the range from -0.18% at the shortest focal length to 0.88% at the longest. With Nikkor 70-200 mm VR we had a range from -0.54 to 0.87%, with Canon 70-200 mm f/2.8 IS from -0.39% to 0.54%, and with the older Sigma from -0.47% to 0.80%.

The successor doesn’t diverge much from the results recorded by the lenses listed above. At the shortest focal length we’re dealing with a barrel distortion of a minimum -0.24% value, which changes the sign and increases to 0.64% at 135 mm, to reach a maximum 0.94% value at 200 mm. After adding the converter aberrations lower slightly to 0.82%.
