The fastest Nikon AIS lens is the Nikkor 85mm f/1.4D, which was released in 1993. This lens offers outstanding sharpness and contrast even at its maximum aperture, making it perfect for low-light photography such as night landscapes or portraiture. The fast 1.4 aperture also allows photographers to achieve shallow depth of field effects with ease, allowing them to isolate their subject from the background. With an ultra-large 9-blade circular diaphragm, this lens produces stunningly smooth bokeh that will add an artistic touch to any image.
