Hasselblad XCD 35-75mm f/3.5-4.5

Distortion for Hasselblad XCD 35-75mm f3.5-4.5

Distortion varies by focal length, from pronounced barrel distortion at the wide end to moderate pincushion distortion at the long end. It is enough that distortion correction will often be necessary for credible work, and that will degrade micro contrast, making the MTF charts rather deceptive in merit when distortion correction is applied. However, even Zeiss does this with some of its lenses as does Fujifilm and others—I am not a fan of this kind of optical compromise.

@ 35mm

Barrel distortion (bowing outwards) at 35mm is very high at about 3.25%. That degree of distortion will require distortion correction for horizons, architecture, and even groups of people. I am not keen on this degree of distortion or the need for correcting it with too many subjects. However, many lenses these days “cheat” by flagging distortion correction in EXIF, hiding it from users and reducing micro contrast in outer zones.
