The EF 11–24 mm f/4L USM lens is a professional wide-angle lens made by Canon Inc. It was announced on February 5, 2015,[1] and at that time was the widest rectilinear lens ever made for the 35 mm format in either its film or digital versions.[2]
The lens has an EF mount to work with the EOS line of cameras. Other than the front element, it is sealed against dust and water, and features a diaphragm which remains nearly circular. It produces minimally distorted images.
