You can do it in AE. Check: http://www.kenrockwell.com/canon/lenses/16-35mm-ii.htm Ken Rockwell maps the lenses he reviews. Then apply adjustment layer on top in comp, and add Lens Distortion filter. Then put Ken Rockwells numbers in. (I think the filter is called that or optics something) You can do almost the same in Magic Bullet Looks. But the easiest would me to import into AE using ACR and choose the right lens!
