Nikon AI-S NIKKOR 600mm f/4s IF-ED Lens

A long-reaching super telephoto designed for sports, wildlife, and nature applications, the AI-S NIKKOR 600mm f/4s IF-ED from Nikon is a manual focus lens featuring AI-S automated aperture control. The optical design incorporates a pair of extra-low dispersion elements to reduce chromatic aberrations and color fringing for improved image quality and color accuracy, and a UV filter is incorporated into the lens' design to both protect as well as cut haze while shooting. Benefitting the manual focus operation of the lens is a preset focusing aid that allows for intuitive rapid re-focusing to a specific set point. An internal focusing design is also employed to maintain the overall lens length as well as promote smoother handling.
