http://www.usa.canon.com/eflenses/technology/index.html and, more specifically, http://www.usa.canon.com/eflenses/technology/lseries.html Besides their use of more expensive Ultralow Dispersion (UD) glass elements, and their exclusive use of Flourite crystal elements, the L-series lenses are constructed for heavy professional use with more rugged cast-alloy barrels, weather sealing, and other features.
