Normal and Expected? or Problem Lens

[piiooo]

I think expected. I have no experience with this lense but I notice this with my 24-105L. My 24-105@24 has 1.8% distortion. The 17-40@17 has 2.47%. The 16-35@16 has 2.37%. Check out Lens Tests / Reviews at http://www.photozone.de/canon-eos

I think they discuss barrel distorsion in the photozone review. This phenomenon also shows up at wide angle, and is actually what fisheye lenses are about.


Perspective distorsion on the other hand is a result ofthe sensor planenot being parallel to the object plane.
