Canon L Lens

Canon L Lens

An L lens is a line of SLR photography lenses made by Canon. L lenses are Canon's top-of-the-line lenses. Some say L stands for "Low Dispersion" - achieved by the UD lens elements found in these lenses. But, the true answer is probably the one in Canon's Lens Work III Book - "L" is 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).

The lens on the Canon PowerShot Pro1 was designated L-series, and was the first fixed (non-interchangeable) lens so designated.
