A Big Dick Lens (BDL) is any camera lens bought primarily by men in mid life crisis for the
sake of male enhancement. A BDL is exorbitantly expensive, providing it's owner with a feeling of
smug superiority. Examples include the Leica Noctilux-M 50mm f/0.95 ASPH., which retails for
almost $12,000. Nobody needs a BDL for any useful purpose, it's purely for show.
