| 17-50mm F/4 Di III VXD (Model A068) For Sony E-mount | October 19, 2023 |
This lens zooms from 17mm ultra wide-angle to 50mm standard, the world’s first 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. 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. 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 HIGHLIGHTS
1. Zoom lens that covers ultra wide-angle to standard focal length at constant F4 aperture
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. 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 range
With 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 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. Internal zoom for superlative balance
The 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. 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
The 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.
5. Close-range shooting performance expands versatility
The 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.
