Introducing the Tamron 17-50mm

• Full-Frame | Constant Max Aperture: f/4
• Ultra-Wide to Normal Zoom Lens
• VXD Linear Motor Focus Mechanism
• Internal Zoom & Focus
• Moisture-Resistant Construction
• Fluorine Coating

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 perspectives 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.

Features & Functions

Advanced optical performance with rich bokeh at F4

The optical construction of the 17-50mm F4 consists of 15 elements in 13 groups. The precise arrangement of special lens elements, including three LD, one GM and two hybrid aspherical lens elements, effectively suppresses chromatic and other aberrations. Full frame resolution with clarity and sharpness, and full use of the rich bokeh provided by the wide F4 aperture, bring you closer to that perfect shot.

Compact, lightweight body and internal zoom for comfortable shooting

The 17-50mm F4 weighs just 460g (16.2oz) and is a compact 114.4mm (4.5in) long, a size that's well-balanced even when attached to a Sony mirrorless camera body. The lens has a fixed barrel length and internal zoom mechanism, making it easy to keep the shot in focus when shooting stills or video, and easy to balance with a video rig or gimbal stabiliser. The highly portable 17-50mm F4 features moisture-resistant construction and fluorine coating on the front and rear lens surfaces for durability in natural environments.

Compatible with TAMRON Lens Utility™ software

The 17-50mm F/4 Di III VXD is compatible with the TAMRON Lens Utility software developed in-house by TAMRON. TAMRON Lens Utility lets users change lens settings, assign camera body functions, and update firmware when necessary. Users may customize functions for various still photography and videography shooting styles, for a more personalized and fulfilling shooting experience.

Additional product features

Voice-Coil Extreme-Torque Drive – The VXD autofocus guarantees fast and precise focusing on both near and far objects. The quiet focus motor responds at lightning speed and is particularly suitable for images of moving objects.

Low Dispersion – LD elements have particularly low colour dispersion index. They reduce chromatic aberrations that appear as colour fringes on the contrast edges and reduce image sharpness.

Internal Focus – Internal focusing prevents the barrel from extending and rotating during focusing. The lens is easier to handle and is suitable for use with polarising or gradation filters.

The new TAMRON Lens Utility software was developed by us to configure our own TAMRON lenses. After installing the program on a computer, compatible lenses can be connected to the computer via a connecting cable to customize various lens functions or to update the lens firmware.

Broad Band Anti-Reflection– The BBAR multi-coating ensures brilliant images with natural colours. It reduces the reflection of light rays hitting the lens surface. The more advanced BBAR G2 coating has been used since 2019.

Moisture Resistant Construction – The lens is splash-resistant. All critical areas have special seals. Lenses with this feature are ideal for outdoor use in bad weather.

Fluorine Coating – Fluorine Coating protects the front lens from contamination. It prevents oil and water droplets from sticking to the surface. Fingerprints and dirt are easier to remove.
