EF 85mm f/1.8 USM
The EF 85mm f/1.8 USM works as a great portrait lens because of its fast aperture of f/1.8 which is ideal for creating a nice interesting bokeh. The lens front elements do not rotate during focusing, a great advantage no doubt, as it helps to keep the polarizing or other filters properly dialed even when recomposing. It also has USM (Ultra-sonic Motor) which facilitates fast and quiet focusing.
A highly practical medium telephoto lens with superb delineation and portability. Images are sharp and clear at all apertures. Through computer simulations, the lens has been designed to give beautiful background blur. Since the front lens group does not rotate during focusing special filter effects are not affected.
