Description
Category-disrupting ‘standard zoom’ for still photography and video
Driven by a determined quest for portability, the 20-40mm F/2.8 Di III VXD (Model A062) is TAMRON’s innovative, fast-aperture Sony E-mount zoom lens that will change your mind about standard zooms. The lens starts from 20mm at the ultra wide-angle end and covers up to 40mm in the standard focal range. Despite the breadth of the zoom range, it still offers class-leading compact size and light weight. Useful in a wide variety of shooting situations, the new zoom is ideal for everything from casual snaps and family events to landscapes captured with natural compositions and perspective, and even indoor photography in tight quarters using the ultra wide-angle. In addition, since the 20mm wide-angle field-of-view captures scenes in all their glory, it is also ideal for self-shooting during vlogs and other content. The lens’s AF drive uses the fast and high-precision linear motor focus mechanism VXD (Voice-coil eXtreme-torque Drive). The optical design makes use of special lens elements and strikes a perfect balance between a compact body and high image quality. The lens offers excellent close-shooting performance, offering wide macro shooting with an MOD (Minimum Object Distance) of 0.17m (6.7 in) and maximum magnification ratio of 1:3.8 at the 20mm end. All these exciting features are brought together into a super-compact package, making the 20-40mm F2.8 a lens that lets you enjoy hassle-free shooting. The high-quality finish pleases the eye, while the exceptional portability and light weight of this fast F2.8 lens means you’ll always want it with you as you pursue a joyful world of photographic encounters.
1 Among the fast-aperture zoom lenses for Sony E-mount full-frame mirrorless cameras (As of August, 2022: TAMRON)
An unprecedented compact and lightweight design that shatters stereotypes of fast-aperture zoom lenses
The 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 in) 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.
Control the composition as you shift seamlessly from the ultra wide-angle to the standard focal length
The 20-40mm F2.8 covers the focal length range of 20-40mm, making it a fast-aperture standard zoom lens for full-frame mirrorless cameras that offers true ultra wide-angle. Compared to a conventional zoom lens that starts at 24mm, the difference is obvious the minute you bring the camera to your eye. When shooting landscapes, you can enjoy the wide-angle field-of-view and dynamic performance that only an ultra wide-angle lens delivers. Moving in the other direction, the full zoom range covers up to 40mm, also offering popular 28mm and 35mm lengths. So, it’s ideal for snaps and casual portrait, too. When attached to an APS-C mirrorless camera, it covers the full-frame equivalent focal length range of 30-60mm that also covers the common standard range.

Awesome videos and selfies at 20mm with fast, high-precision AF
The excellent handling benefits inherent in the compact and lightweight design are especially useful when shooting video. The lens remains well-balanced when using a camera rig, cage, or gimbal stabilizer, so it’s an excellent choice for vlog shooting. One advantage of the 20mm ultra-wide focal length is that a broad expanse of the background can be incorporated when selfie shooting. What’s more, the AF drive system is equipped with the VXD linear motor focus mechanism. Thanks to the high-speed, high-precision AF, speedy, pinpoint focusing is certain at any point of focus from the MOD to infinity. Excellent focus tracking performance allows you to track movement steadily when shooting video. In addition, noise from the AF motor has been minimized, making it ideal for still and video when shooting in conditions where silence is required.
Compact body with high image quality
The 20-40mm F2.8 is packed with unique TAMRON innovations that enable it to have a compact body while ensuring high image quality. The optical construction has 12 elements in 11 groups. The precision design features a generous arrangement special lens elements including four LD (Low Dispersion) lens elements that control light dispersion, and two GM (Glass Molded aspherical) lens elements which combine to produce high optical performance. One of the greatest appeals of this zoom is the creamy, beautiful bokeh that is distinctive to fast-aperture lenses. Additionally, the BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating, TAMRON’s next-generation technology, suppresses ghosting and flare to enable the crisp and clear rendering of images.

Close-focusing wide macro shooting with an MOD of 0.17m (6.7 in) at the 20mm end
Unique wide macro shooting at close-up distances emphasizes perspective to heighten the impact of a composition, and it’s only possible with an ultra wide-angle. The excellent close-range shooting performance, which achieves an MOD of 0.17m (6.7 in) at the 20mm wide end with a maximum magnification ratio of 1:3.8, produces rich and dynamic imagery that brings out the finest details of the subject and gives you another avenue of creativity.

New 2nd-generation lens design improves both operation and ergonomics
The 20-40mm F2.8 incorporates a new design that becomes the hallmark of TAMRON lenses introduced in the future. In constant pursuit of improving products in every way possible, TAMRON considered customer feedback and reviewed each part and component of the lens down to the finest details. As a result, TAMRON has enhanced both the operation and tactile presentation of the lens.
The arc of rotation of the zoom ring is only 65°. This enables swift adjustment to the desired focal length with minimal movement.
The diameters of the zoom ring and focus ring have been enlarged, and the body areas around them have been slimmed down to give the lens a contoured profile that makes it easier to grip. This creates a comfortable, uneven shape that fits snugly and naturally in the hand.
Every individual part of the lens has been reexamined, right down to the fine details, resulting in a new design that updates both operability and the ergonomic considerations. The surface of the lens exterior is shiny black, much glossier than previous models. Improved abrasion resistance makes the lens harder to scratch and resists fingerprints. In addition, grip performance has been improved by increasing the number of protrusions in the striped pattern of the rubber ring. The smoothly curved, glossy surface of the brand ring creates a dignified appearance with a design that signifies functional beauty and high quality.
