Lens Overview
Standard Zoom Gets a New Start! Zoom from 20mm Ultra Wide-Angle to Normal.
The Tamron 20-40mm F2.8 is a fast-aperture standard zoom lens but maintains its fast F2.8 aperture across the entire zoom range while sporting a remarkably compact and lightweight design, just 86.5mm (3.4″) long, with a maximum diameter of 74.4mm and weight of only 365g (12.9 oz). With a size that is easy to carry and a light weight that’s well-suited for handheld shooting for extended periods, the 20-40mm F2.8 will likely become your first choice for travel, street shooting, everyday carry, and spontaneous photo opportunities.
Class-Leading* Compactness — Redefining the Fast-Aperture Zoom
The 20-40mm F/2.8 Di III VXD (Model A062) defies the conventional expectations for a fast-aperture standard zoom lens. While delivering a constant F2.8 aperture across the entire zoom range, it achieves a class-leading compact and lightweight design. With a length of just 86.5mm (3.4″) and weighing only 365g (12.9oz),** the 20-40mm F2.8 offers incredible portability. Its exceptional size and weight provide the mobility you need for everything from daily snapshots and travel to dedicated creative work.
*Among the fast-aperture F2.8 standard zoom lenses for full-frame mirrorless cameras (As of August 2022 – TAMRON)
**Length and weight are for Sony E-mount lens.
Expanding Your Creative Horizons from Ultra-Wide 20mm — A Seamless Flow to the Natural 40mm View
The Tamron 20-40mm F2.8 features a unique focal range starting at 20mm. At the 20mm ultra wide-angle end, it provides a sense of depth and scale that conventional standard zoom lenses simply cannot match, capturing the full essence of a landscape. At the same time, the range up to 40mm is ideal for everyday snapshots and portraits. When used with APS-C mirrorless cameras, it provides a full-frame equivalent of 30-60mm — offering the flexibility to handle any scene without changing lens.
Mobility and High-Speed, High-Precision AF — The Perfect Support for Video and Vlogging
The compact, lightweight design ensures exceptional handling, offering a significant advantage for video shooting. The 20-40mm F2.8 remains perfectly balanced even when mounted on camera grips or compact gimbals, making it ideal for handheld shooting and vlogging. Additionally, the 20mm focal length lets you capture the broader background while maintaining a comfortable distance for selfies. The AF drive features the VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism. This high-speed, high-precision system tracks subjects smoothly and accurately from MOD (Minimum Object Distance) to infinity, reliably following moving subjects during video shooting. Furthermore, the quietness of the linear motor allows for inconspicuous shooting in noise-sensitive environments, whether for stills or video.
*Operational sounds may be recorded in video depending on the shooting environment.
High Image Quality in a Compact Body — Powered by Specialized Lens Elements
The 20-40mm F2.8 is packed with TAMRON’s proprietary optical technologies, delivering imaging performance that defies its compact size. The optical construction features 12 elements in 11 groups. By generously incorporating specialized lens elements, including four LD (Low Dispersion), along with two GM (Glass Molded Aspherical) lens elements, the 20-40mm F2.8 achieves outstanding optical performance. A key highlight is the beautiful, soft bokeh that only a fast F2.8 aperture can provide. Furthermore, the BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating effectively suppresses ghosting and flare, ensuring clear and crisp images with excellent contrast.
Wide Macro Shooting with an MOD of 0.17m (6.7in) — Discover the Power of Close-Ups
With an MOD of just 0.17m (6.7in) and a maximum magnification ratio of 1:3.8 at the 20mm wide end, the 20-40mm F2.8 delivers impressive wide macro photography. By getting remarkably close to your subject, you can capture it in stunning detail while still including the expansive background. This allows for powerful, creative expression, emphasizing the unique sense of perspective and depth only wide-angle shooting can provide.
Compatible with TAMRON Lens Utility™ Application
TAMRON Lens Utility is an innovative application that lets you assign practical functions to your lens for both video and still photography using your smartphone or PC, eliminating the need for traditional video equipment.
Enhanced Convenience and Operability
Zoom Ring Rotation Angle of 65° for Smooth Zooming with Minimal Movement
The 20-40mm F2.8 features a zoom ring rotation angle of just 65°. This allows for quick zoom adjustments with minimal movement, ensuring a smooth shooting flow without ever missing a moment.
Enhanced Exterior Surface
Our engineers refined every structural detail to enhance usability and ergonomics. The lens exterior has a glossy black finish with improved abrasion resistance to reduce scratches and fingerprints. The material on the zoom and focus rings is also updated to offer better grip performance with deeper grooves, while the smoothly curved glossy brand ring presents a dignified, high-quality look.
Unified 67mm filter size
Most TAMRON mirrorless lenses feature a 67mm filter size, allowing shared use of expensive PL or ND filters and eliminating the hassle of switching lens caps. All lenses are compact, lightweight and extremely portable, ideal for multi-lens shooting.

Features
A 9-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.
TAMRON has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.
The 20-40mm F2.8 is compatible with the dedicated TAMRON Lens Utility software for computers and devices with Android™ [1] OS that was developed in-house by TAMRON[2]. TAMRON Lens Utility will let users customize focus ring settings and update to the latest firmware[3] when necessary. In addition, by using the Mobile version, Focus Preset and A-B Focus is available, and those functions can be operated remotely without touching the lens. Users may customize functions for various still photography and videography shooting styles, thereby providing a more personalized and fulfilling shooting experience.
