The lens is incredibly compact at 185.8mm (7.3-inch) long and light at just 1180g (41.6oz). It is lighter and more compact than a conventional 100-400mm class zoom, and it is comfortable to carry all day. The 50-400mm F4.5-6.3 VC is equipped with Tamrons VXD linear motor focus mechanism and VC image stabilization mechanism. The precise arrangement of special lens elements effectively delivers uncompromising high image quality throughout the entire zoom range. The wider end of the Tamron A067Z 50-400mm Zoom Lens for Nikon Z Mount is particularly useful for side-line sports, wildlife and other subjects that move closer as you are shooting, allowing you to continue photographing without changing lenses.
