Description
The Canon EF 1.4x III Extender increases a compatible EF telephoto lens’s focal length by 1.4x, with minimal loss of light or image quality. Pairs with lenses like the Canon 70-200mm f/2.8L IS III and 300mm f/2.8L IS II.
The Mark III version adds enhanced environmental seals and a redesigned optical assembly, keeping full autofocus, shooting functionality and metadata communication with a compatible camera. Dust- and water-resistant construction and a fast-mounting release mechanism suit demanding conditions.
