Distortion of group photos using wide angle
As measured on the optical bench, the distortion of a 24-105 is larger than the 24-70 at 24mm.
I have read that 24-70 is better for building shots because of the lower distortion. However, for group photos of people, the 24-105 is better because there is less stretching of the image at the edges so people at the edges of the group are not distorted as much. Could someone comment if this argument is correct and provide some samples of group shots at 24mm? Very much appreciated.
