Canon L lensとは 意味・読み方・使い方

An L lens is a line of SLR photography lenses made by Canon. L lenses are Canon's top-of-the-line lenses. The "L" officially stands for "Luxury", a reference to the lenses' high price and proclaimed build quality. The use of "ASPH" was common to notate aspherical elements throughout Canon's and other manufacturers' histories. Canon produces both L-series zoom and prime lenses for their obsolete FD lens mount and for their current EF lens mount used on all Canon EOS cameras (digital and film).
