Tamron 17-50mm f/4.0 Di III VXD lens for Sony

The world’s first lens that covers from ultra wide-angle through the standard range
The 17-50mm F/4 Di III VXD covers a versatile zoom range from ultra-wide through standard focal lengths – no need to switch lenses. From dynamic landscapes to casual snaps and portraits in the standard range, the rich variation is possible with a single compact lens. The excellent close-range shooting performance provides an MOD of 0.19m at the wide end and 0.3m at the tele end. What’s more, the constant f/4 aperture throughout the whole range makes it ideal not just for still images but also video shooting. The 17-50mm f/4 will dramatically expand your range of expression, paving the way to all-new creative photographic experiences.

Advanced optical performance with rich bokeh at f/4
The optical construction of the 17-50mm f/4 consists of 15 elements in 13 groups. The precise arrangement of special lens elements, including three LD, one GM and two hybrid aspherical lens elements, effectively suppresses chromatic and other aberrations. Full frame resolution with clarity and sharpness, and full use of the rich bokeh provided by the wide f/4 aperture, bring you closer to that perfect shot.

Compact, lightweight body and internal zoom for comfortable shooting
The 17-50mm f/4 weighs just 460 g (16.2oz) and is a compact 114.4 mm (4.5in) long, a size that's well-balanced even when attached to a Sony mirrorless camera body. The lens has a fixed barrel length and internal zoom mechanism, making it easy to keep the shot in focus when shooting stills or video, and easy to balance with a video rig or gimbal stabiliser. The highly portable 17-50mm f/4 features moisture-resistant construction and fluorine coating on the front and rear lens surfaces for durability in natural environments.
