Tamron 20-40mm F/2.8 Di III VXD Lens for Sony E-mount

The Tamron 20-40mm F/2.8 Di III VXD Lens for Sony E-mount is a wide-angle zoom lens with a 35mm equivalent focal length range of 30-60mm. It features a maximum aperture of f/2.8, which offers depth-of-field control and low-light shooting capabilities along with the ability to produce images with a shallow depth of field. This lens also features a linear motor focus mechanism that provides fast and quiet autofocus performance while also enabling full-time manual focus override at any time.
The lens's optical construction consists of 12 elements in 11 groups, four low dispersion elements, two glass molded aspherical lenses, and one hybrid aspherical element that help minimize chromatic aberrations throughout the focusing range for sharp, color-accurate imagery. Its diaphragm helps in producing smooth bokeh effects when working with shallow depth of fields.

Product Features in Detail

Fast F2.8 aperture, compact size and exceptionally versatile 20-40mm zoom range
The 20-40mm F2.8 is TAMRON's innovative creation of a new standard zoom lens, born from the unbridled desire to produce a compact size that can be carried around easily. It delivers a fast F2.8 aperture across the entire zoom range from 20mm to 40mm and achieves a class-leading compact and lightweight design at just 86.5mm (3.4 in) and 365g (12.9 oz). At the longest zoom end, the lens offers a standard focal range of 40mm, handy for everyday shooting of snaps, portraits, and food photos. Meanwhile at the wide end, the ultra-wide 20mm focal length lets users enjoy a broad range of photography including stunning and powerful natural landscapes that make use of the unique ultra wide-angle perspective, something that cannot be expressed as readily with a fast-aperture standard zoom lens that starts at 24mm.

Fabulous family videos, vlogs, and other online content
The compact and lightweight 20-40mm F2.8 offers excellent handling that is well balanced even when accessories like camera grips or gimbal stabilizers are attached. With this single lens, you won't miss a shot, from street videography to vast landscapes during travel and selfies that include wide backgrounds.

A new proposition from TAMRON! Three key points of the 20-40mm F2.8, a compact and lightweight fast-aperture standard zoom lens that starts at 20mm!
Finally, a zoom lens designed and built to work the way you do—instead of way lenses were used in 1950. Seventy years ago, photographers shot 35mm film and most cameras had 50mm lenses. That focal length was selected as the standard because the perspective it captures is close to what the human eye sees normally—minus the peripheral vision.
You don’t use your camera in the limited ways that were predominate long ago, before digital. You capture still images, but you also shoot video, so you need a more versatile zoom, and that changes everything. Finding a zoom lens highly suitable for both stills and videos has been challenging—unless you were willing to carry around a lens that is bigger and heavier than average. Challenging—until now.
Here, TAMRON presents some photos/images that illustrate both the practical and creative key points of the 20-40mm F/2.8 Di III VXD (Model A062).

Unrivalled portability - Staying on the camera at all times
People enjoy photography in many different ways, but one thing we all have in common: experiencing that moment of regret we feel when there is a shot we want to take but don’t have our camera—or the right lens—with us.
TAMRON has succeeded in making the 20-40mm F2.8 smaller and lighter, coming it at just 86.5mm (3.4 in) long and weighing only 365g (12.9 oz). This is a walkaround lens that you can keep on the camera all day and be confident you never miss a photo opportunity in daily life or when traveling.

Fast F2.8 aperture starting at 20mm standard zoom
TAMRON created the 20-40mm F2.8 as a new option for a fast-aperture standard zoom lens, especially as a vlogger’s standard zoom, and as a regular everyday, take everywhere lens.
The 20-40mm F2.8 is compatible with full-frame mirrorless cameras AND starts at the breathtaking 20mm focal length. Taking advantage of the benefits of the 20mm ultra wide-angle at the wide end, dynamic natural landscapes that emphasize perspective are just the beginning.
Set at the 40mm standard focal length, the lens works well in a wide range of shooting scenes, including snaps and portraits that make use of the beautiful bokeh at F2.8.
When combined with the in-camera crop function or on an APS-C mirrorless camera, the lens covers a focal length range equivalent to 30-60mm in full-frame format. For those who find 40mm to be not quite enough for their purposes, this lens offers a 20-60mm equivalent zoom range on a full-frame camera by activating the in-camera crop function without swapping lenses.

Easily enjoyable videography
The versatile 20-40mm F2.8 covers from the ultra wide-angle commonly used in video shooting to the standard focal range with a single lens. Additionally, with its compact and lightweight design, the lens is well balanced even when accessories like a camera grip or gimbal stabilizer are attached, unlike heavier weight-forward zooms. All in all, it’s a good choice for vlog shooting. When shooting at the 20mm wide end, you can shoot selfies that include the background, something that’s difficult to do even with a 24mm focal length.
For accurate and quiet autofocusing, the lens is equipped with an impressively quiet VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism. This delivers stress-free focusing and excellent focus tracking of moving subjects. As the lens offers an F2.8 aperture across the complete zoom range, you can also enjoy video shooting that makes use of beautiful bokeh.
The 20-40mm F2.8 also features excellent close-up shooting capabilities, with a Minimum Object Distance of 0.17m (6.7 in) at the 20mm end and 0.29m (11.4 in) at the 40mm end. The ability to record a variety of scenes with its wide angle-of-view that would be captured using a mobile phone expands the possibilities of expression.
