Designed for Sony mirrorless cameras, this groundbreaking wide-angle zoom covers ultra wide-angle to standard focal lengths with a constant F4 aperture and is ideal for both still photography and video recording. It achieves excellent optical performance across the entire zoom range, with crispness from edge-to-edge. The lens also incorporates TAMRON's VXD linear motor focus mechanism for superior quietness and agile performance and achieves high-speed and high-precision autofocus. 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 attached to a gimbal stabilizer or other equipment. The excellent close-range shooting performance provides an MOD (Minimum Object Distance) of 0.19m (7.5") at the wide end and 0.3m (11.8") at the tele end. The ideal “walk around” lens, the new TAMRON 17-50mm F4 offers great portability and convenience and makes it possible to shoot a variety of still and video content, from sweeping landscapes to snapshots, all without switching lenses.
No 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.
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 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.
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, 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.
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. Thanks to the quiet operation during AF, the lens is superb when shooting still images or video for low noise shooting in silent settings.
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. 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.
