From capturing breathtaking landscapes to intimate portraits, the 17-70mm f/2.8 Di Iii-a Vc Rxd Lens for Fujifilm X is a versatile and high-quality lens designed for the discerning photographer. This innovative lens boasts a constant maximum aperture of F2.8 across its entire 4.1x zoom range, covering a focal length of 17-70mm, equivalent to 25.5-105mm on full-frame cameras. This makes it the world's first fast-aperture standard zoom lens for Aps-c mirrorless cameras with such a broad zoom ratio.Constructed with 16 elements in 12 groups, including two Gm (Glass Molded Aspherical) and one hybrid aspherical lens elements, this lens ensures high-resolution performance from edge to edge. Its compact and lightweight design, coupled with Tamron's proprietary Vc (Vibration Compensation) mechanism, minimizes camera shake, making it a reliable choice for both photography and videography.
