The Tamron 17-50mm f/4 Di III VXD Lens suits both video and photo needs with a unique focal length range that includes an ultra-wide 17mm position that's perfect for broad fields of view as well as for interior settings, architectural subjects, and even when recording vlogs at arm's length. The range extends to 50mm, offering a normal-length field of view, that suits portraits and tighter perspective of everyday subjects. Also, it has impressive close-up performance, with a 7.5" minimum focusing distance at the wide end and 11.8" on the long end, for working with nearby subjects. This flexible range is backed by a constant f/4 maximum aperture that helps prioritize portability and make this an ideal walkaround lens.The lens design is also well-suited to multimedia use with the inclusion of a VXD (Voice-coil eXtreme-torque Drive) linear motor for quick and quiet autofocus performance. The lens also has an internal zoom and internal focus design, meaning the overall length doesn't change during use for more intuitive handling that is easy to balance when working with a gimbal stabilizer.Additionally, in terms of physical design, the 17-50mm has a moisture-resistant design with a front fluorine coating that makes cleaning simple and straightforward. It uses 67mm filters, just like most other Tamron mirrorless lenses, and it's also compatible with the Tamron Lens Utility software for fine-tuning lens performance to suit your needs..This groundbreaking lens zooms from 17mm ultra wide-angle to 50mm standard, the world’s first1 with such a dynamic zoom range for full-frame mirrorless cameras. TAMRON’s new 17-50mm F4 for Sony mirrorless cameras is a wide-angle zoom with a constant F4 aperture covering ultra wide-angle to standard focal lengths, a zoom range ideal for both still photography and video recording. This lens achieves excellent optical performance across the entire zoom range, with crispness from edge-to-edge. The lens also incorporates VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism with superior quietness and agile performance and achieves high-speed and high-precision autofocus. Additionally, the physical length of the lens does not change while zooming. It’s the perfect lens for taking still photos and is also ideal for video shooting, in part since it’s easy to balance even when fitted to a gimbal stabilizer or other equipment. The excellent close-range shooting performance provides an MOD (Minimum Object Distance) of 0.19m (7.5in) at the wide end and 0.3m (11.8in) at the tele end. This lets users get closer to the subject to capture one-of-a-kind photos in a broad range of situations. The ideal “walk around” lens, the new 17-50mm F4 zoom offers great portability and convenience and makes it possible to shoot a variety of content, both still images and video, from sweeping landscapes to snapshots, all without switching lenses.PRODUCT HIGHLIGHTS1. Zoom lens that covers ultra wide-angle to standard focal length at constant F4 apertureNo need to switch lenses— users can zoom from ultra wide-angle 17mm for dynamic expressions to snapshot photography at the 50mm standard focal length end, an angle of view close to that of human vision. What’s more, the wide-open aperture of F4 is consistent across the entire zoom range and thereby maintains constant exposure when zoomed in or out. Whether shooting still images or video, the new 17-50mm F4 has you covered.2. High optical performance and image quality throughout the entire zoom rangeWith the expert arrangement of 15 lens elements in 13 groups, including three LD (Low Dispersion), a GM (Glass Molded Aspherical), and two hybrid aspherical lens elements. the new 17-50mm lens efficiently suppresses chromatic and other optical aberrations, ensuring clear capture of fine details from edge-to-edge in all images. The lens also delivers outstanding bokeh at the F4 wide open aperture, creating appealing shots in which subjects such as trees and flowers that color the seasons pop out against the background in natural landscape photography.3. Compact for easy handling with internal zoom for superlative balanceThe 17-50mm F4 weighs just 460g (16.2oz) and is only 114.4mm (4.5in) long, a form factor that is well-balanced on a Sony mirrorless camera body. The lens employs an internal zoom mechanism that keeps the lens barrel at its fixed length, so it’s easy to balance when framing still or video shots or when paired with a video rig or gimbal stabilizer. Additionally, the new zoom features Moisture-Resistant Construction and Fluorine Coating. The easy handling provided by its compact size makes it a great choice for active scenarios such as mountain climbing or other outdoor activities.4. Fast and accurate AF for still and video shootingThe 17-50mm F4’s AF drive uses VXD linear motor focus mechanism to achieve class-leading high-speed and high-precision auto-focusing. With fast and accurate focusing of moving objects, plus excellent subject-tracking performance, users can readily shift into a fast-paced shooting rhythm. Thanks to the quiet operation during AF, the lens is superb when shooting still images or video for low noise shooting in silent settings.5. Outstanding close-range shooting performance expands versatilityThe MOD of the 17-50mm F4 are 0.19m (7.5in) at the wide end and 0.30m (11.8in) at the standard 50mm end. The working distance at 17mm is only about 5.7cm (2.3in), closer even than most non-zoom lenses. Users can freely get close to the subject and can enlarge the foreground against a blurred background, or comfortably focus without needing to change their shooting position even in places with limited space.6.
