Canon EF 400mm f/4.0 DO IS USM

The big difference between the Canon EF 400mm f/4.0 DO IS USM and other super telephoto lenses is the size of the EF 400mm f/4.0 DO IS USM. Canon have utilised Diffractive Optical (DO) technology with this lens. This helps to radically reduce the size and weight of the lens. As well as the Diffractive Optical lens element Canon have added a fluorite lens element to further enhance image quality. Build quality is impressive with the lens being built to Canon Luxury lens standards.

Another difference between this and other lenses is that it has a 52mm rear drop in filter holder.
