As an outstanding travel accessory, this full-frame lens produces stunning images throughout its zoom range, making it an excellent option for still photography, vlogs, and various video projects.

Compact and Lightweight Design

The 20-40mm f/2.8 is a standard zoom lens characterized by its fast aperture, which remains consistent at f/2.8 throughout the entire zoom range. Its design is notably compact and lightweight, measuring just 86.5mm (3.4 inches) in length, with a maximum diameter of 74.4mm and a weight of only 365g (12.9 oz). This lens is not only easy to transport but also ideal for handheld shooting over extended periods. As a result, the 20-40mm f/2.8 is likely to be your preferred option for travel, street photography, daily use, and capturing spontaneous moments.

Focal Range

The 20-40mm f/2.8 lens encompasses a focal length range of 20-40mm, serving as a fast-aperture standard zoom lens designed for full-frame mirrorless cameras, providing a genuine ultra wide-angle experience. In contrast to a traditional zoom lens that begins at 24mm, the distinction becomes immediately apparent when the camera is raised to the eye. While capturing landscapes, photographers can appreciate the expansive field of view and dynamic capabilities that are characteristic of an ultra wide-angle lens. Additionally, the full zoom range extends to 40mm, which includes the widely used 28mm and 35mm focal lengths, making it suitable for casual snapshots and portrait photography as well. When utilized with an APS-C mirrorless camera, it offers a full-frame equivalent focal length range of 30-60mm, effectively covering the standard range commonly sought after.

High-Precision AF

The remarkable handling advantages associated with the compact and lightweight design are particularly beneficial for video recording. The lens maintains a well-balanced state when utilized with a camera rig, cage, or gimbal stabilizer, making it an outstanding option for vlogging. One notable benefit of the 20mm ultra-wide focal length is its ability to capture a wide background during selfie shots. Furthermore, the autofocus drive system features the VXD linear motor focus mechanism. This high-speed, high-precision autofocus ensures rapid and accurate focusing at any distance, from the minimum object distance to infinity. The exceptional focus tracking capability enables steady movement tracking during video capture. Additionally, the noise produced by the autofocus motor has been significantly reduced, rendering it suitable for both still photography and video in environments where silence is essential.

Optical Design

The 20-40mm f/2.8 lens incorporates several innovative features from TAMRON, allowing it to maintain a compact design while delivering exceptional image quality. Its optical architecture consists of 12 elements arranged in 11 groups. This meticulously crafted design includes a thoughtful arrangement of specialized lens elements, featuring four Low Dispersion (LD) elements that effectively manage light dispersion, along with two Glass Molded Aspherical (GM) elements that work together to achieve superior optical performance. A notable highlight of this zoom lens is its ability to produce a smooth and aesthetically pleasing bokeh, characteristic of lenses with wide apertures. Furthermore, the BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating, representing TAMRON's advanced technology, minimizes ghosting and flare, ensuring images are rendered with clarity and precision.

Wide Macro Shooting

Distinctive wide macro photography at close distances accentuates perspective, thereby enhancing the overall impact of a composition, achievable solely with an ultra wide-angle lens. The remarkable performance in close-range shooting, which attains a minimum object distance (MOD) of 0.17m (6.7 in) at the 20mm wide setting and offers a maximum magnification ratio of 1:3.8, generates vivid and dynamic images that reveal intricate details of the subject, providing an additional avenue for creative expression.

TAMRON Lens Utility™

The 20-40mm f/2.8 lens is designed to work seamlessly with the proprietary TAMRON Lens Utility software, which is available for both PC and Android™ devices. This software, developed internally by TAMRON, allows users to tailor focus ring settings and perform firmware updates as needed. Furthermore, the Mobile version of the software offers features such as Focus Preset and A-B Focus, which can be controlled remotely, eliminating the need to physically interact with the lens. Users have the opportunity to customize functionalities to suit various styles of still photography and videography, enhancing their overall shooting experience.
