"L" does not constitute any specific coating. According to
Canon the L brand is given to lenses using special materials
such as fluorite, extra low dispersion glass or other
sophisticated techniques. It may also be given to excepionally
good lenses using standard materials. So "L" means that
a lens is rated highest performance according to Canons
standards. It is not neccesarily associated wit he use
of any specific material or coating technology.
