One of the top medium range prime lenses, the 85 f/1.4 is phenomenally sharp and is known for its smooth bokeh in out-of-focus regions which, combined with its narrow depth of field, gives a remarkable 3-D effect. Its often used as a long portrait lens or for indoor sports.
Please note: This lens does not have a built-in autofocus motor. Therefore, it is not fully compatible with Nikon DSLRs such as the Nikon D40, D50, D3100, D5100, etc.
