Lightweight and Compact Design — Your Essential “Go-To Zoom”

By achieving an optimal balance of advanced optical design with special lens elements and refined mechanical engineering, TAMRON created a remarkably lightweight and compact lens. Measuring just 79.6mm (3.2in) in length, weighing a mere 305g (10.8oz),² and featuring a 55mm filter size, it is the essential “Go-To Zoom.” This streamlined build minimizes the burden during travel or outdoor activities, while carefully selected barrel materials, including metal, and an ingenious internal design ensure high structural rigidity for reliable shooting anywhere.

Fast F2.8 Aperture Produces Expressive Bokeh and Rendering

This lens defies its compact size by delivering a constant fast F2.8 aperture throughout the entire zoom range starting at 16mm wide. The exceptional optical design offers a beautiful combination of soft bokeh and sharp rendering, effortlessly highlighting your subject for deeply expressive images. The bright F2.8 also enables faster shutter speeds in low-light settings, such as indoors or at dusk, to effectively suppress motion blur when capturing active children or fast-moving amusement park rides.

* If your camera has a lens correction setting (e.g., “Lens Compensation” or similar), please ensure it is set to “ON” or “AUTO.”

High-Speed, High-Precision AF Captures Every Scene Quietly

The AF drive is equipped with the high-speed, high-precision VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism. It reliably captures fleeting spontaneous moments with outstanding subject tracking, smoothly handling the unpredictable movements of pets and children. Furthermore, its superior quiet operation makes it suitable for both still and video shooting in noise-sensitive environments.

Perfect for Travel and Everyday Video Shooting

The 16-50mm F2.8 excels in video shooting, making it ideal for lifestyle clips and travel vlogs (vlogging). The 16mm wide end allows selfie shots while including the background. Its silent AF and excellent balance when mounted on a gimbal or shooting grip ensure a comfortable recording experience. The Sony E-mount and Nikon Z mount versions support TAMRON Lens Utility™,^3,4 allowing users to assign practical functions for videography.

4 The FUJIFILM X mount version is incompatible with TAMRON Lens Utility.

Close-Up Discovery — Adding Joy to Your Day-to-Day

An MOD (Minimum Object Distance) of 0.15m–0.29m (6in–11.5in) delivers exceptional close-up capability. You can effortlessly frame flowers or cafe scenes with broad backgrounds, leveraging the wide-angle perspective without working distance constraints. This proximity expands your creative options, from expansive wide shots to intimate portraits of a sleeping child framed by soft mid-telephoto bokeh.

Refined Lens Design — “Toned Profile Next”

The 16-50mm F2.8 incorporates “Toned Profile Next,” elevating TAMRON’s signature “Toned Profile” design philosophy to the next level. The aesthetic has evolved from a “sculpted form” into a “mechanical style that resonates with the preferences of modern users.” This refined exterior combines a sleek, sophisticated look with the rugged functionality demanded by today’s photographers.

Strap-Hole Front Cap for Enhanced Security and Workflow

Designed to be the perfect “always-on” lens that stays mounted to your camera for everyday use, this lens introduces a newly designed front cap featuring dedicated strap holes on both sides. By securing the cap to the camera strap or body using a commercially available cord, the risk of accidental drops or loss is significantly reduced during transit or spontaneous shooting. With no need to constantly pocket or store the cap, this design streamlines your workflow for agile, responsive shooting — allowing you to focus entirely on the decisive moment.

* Do not lift or carry the lens by the strap while the front cap is attached.
* Some straps may not fit through the hole depending on their thickness or tip shape.
