The Canon EF 85mm f/1.8 USM is a telephoto lens that will blow away typical 16-55mm kit lens with its exceptional sharpness. The lens is also blazingly fast and this provides an opportunity to use high shutter speeds and better performance in low-light situations.
It also has perfect weight and size, which balance the camera nicely. The combination can help user take snaps with very low shutter speeds. This easily translates to better comfort, improving the overall user experience. Users can also easily take advantage of common effects such as bokeh and compression.
