The Tamron 50-400mm F/4.5-6.3 Di III VC VXD (Model A067) is the unprecedented, next-level ultra-telephoto zoom lens for Sony E-mount full-frame mirrorless cameras. Featuring a stunning 8x zoom ratio, it provides a wide range of focal lengths that covers the standard 50mm and stretches all the way to 400mm at the ultra-telephoto end that offers an unmatched level of versatility. With its wide 50mm starting focal length, full-body shots of subjects like wildlife can be captured in the surrounding environment. The wider end of this unique mirrorless zoom lens is particularly useful for side-line sports, wildlife and other subjects that move closer as you are shooting, allowing you to continue photographing without the need to change lenses.
