Combining a versatile wide-angle-to-standard zoom range with a constant f/2.8 aperture, the Tamron 20-40mm f/2.8 Di III VXD Lens for Nikon Z is a compact full-frame zoom designed for everyday photography and video creation. Its broad range covers landscapes, cityscapes, street scenes, portraits, and other everyday subjects, while its portable design makes it an excellent choice for travel, vlogging, and general-purpose shooting.

The constant f/2.8 maximum aperture provides consistent brightness throughout the zoom range while allowing greater control over depth of field. This makes it possible to isolate subjects using selective focus techniques while maintaining the flexibility of a zoom lens.
Tamron's VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism delivers fast, precise, and quiet autofocus performance throughout the zoom range. The lens is also compatible with camera-specific focusing functions such as Fast Hybrid AF and Eye AF, helping provide responsive focusing for both still photography and video.
With a minimum focusing distance of just 6.7 inches, the lens can focus remarkably close to subjects for a wide-angle zoom. Its 1:3.8 maximum magnification ratio provides additional flexibility when photographing close-up subjects and details.
The zoom ring features a 65° rotation arc, allowing rapid changes to the desired focal length with minimal movement. This is particularly useful when quickly adjusting composition while shooting handheld or recording video.
Designed for everyday portability, the lens features a moisture-resistant construction to provide added reliability when working in inclement conditions. A fluorine coating on the front element helps repel dust, dirt, and smears while making the surface easier to clean.
The lens is also compatible with Tamron Lens Utility software, which allows users to customize supported lens functions and update firmware.
