The Sigma A 50–100 mm f/1.8 DC HSM doesn’t have any distortion-related problems. At shorter focal lengths that aberration is actually difficult to notice. At 50 mm you deal with slight barrel distortion of −0.17%. In the middle of the focal range the deformations change sign and reach a still low level of +0.89%. The biggest chances to see the distortion you get at the maximum focal length where it gets to +1.35%.
