Canon EF 24–70mm 2.8
The Canon EF 24–70mm lens is a family of professional EF mount wide-to-normal zoom lenses manufactured and sold by Canon. The first of the family, the EF 24–70mm f/2.8L, was introduced in 2002 to replace the well-regarded 28–70mm f/2.8L. Two later versions were announced in 2012.
