The Canon EF 50mm f/1.0L USM is a historic ultra-fast standard lens for EOS SLRs that features an aperture brighter than any other AF SLR lens. The EF f/1.0 was originally introduced in 1989 alongside a similar EF 85mm f/1.2L USM; the the 50mm was more expensive and sold in smaller quantities than it's less rare telephoto sibling. In 2007 Canon introduced a new L-Series normal lens, the EF 50mm f/1.2L USM. This original EF 50mm f/1.0 model has been discontinued and is increasingly hard to find.
