The wider end of this unique mirrorless zoom 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. The precise arrangement of special lens elements effectively delivers uncompromising high image quality throughout the entire zoom range. The lens is incredibly compact at 185.8mm (7.3") long and light at just 1,180g (41.6oz). Lighter and more compact than a conventional 100-400mm class zoom, it's comfortable to carry all day. The 50-400mm F4.5-6.3 VC is equipped with TAMRON’s VXD linear motor focus mechanism and VC image stabilization mechanism. These features combine with others make it possible to capture sharp images and provide users comfortable shooting opportunities even when shooting wild birds and fast-moving sports action. Additionally, you can enjoy the world of half-macro photography with excellent close-up shooting capabilities. The MOD is a scant 0.25m (9.8") at the 50mm end, and the maximum magnification ratio is 1:2. Furthermore, you can customize certain functions and update the firmware via the Connector Port by using the dedicated TAMRON Lens UtilityTM. For this zoom lens, TAMRON Lens Utility newly offers a “Focus Limiter” function. The 50-400mm F4.5-6.3 VC is clearly a brand-new kind of ultra-telephoto zoom lens covering 50mm standard focal length, outstanding image quality and high portability. This one lens captures a lively world with all the clarity as you desire and can guide you to new photographic experiences.
