TAMRON 20-40mm F2.8 A062: Compact Standard Zoom for Sony E

A Compact Standard Zoom with a Versatile 20-40mm Range

The TAMRON 20-40mm A062 covers an unusually useful range for photographers who want a single compact lens for everyday shooting.

At 20mm, the lens provides an ultra-wide perspective suitable for landscapes, architecture, interiors and group shots. Zooming toward 40mm produces a more natural standard perspective that works well for street photography, portraits, food and everyday scenes.

This combination allows photographers to move from expansive compositions to more intimate framing without changing lenses.

Constant F2.8 Aperture

The lens features a constant F2.8 maximum aperture throughout the 20-40mm zoom range.

A constant aperture provides consistent exposure when zooming and gives photographers greater flexibility when working in low-light environments. The bright F2.8 aperture can also help create attractive background blur at closer focusing distances.

For video creators, maintaining F2.8 throughout the zoom range makes it easier to maintain consistent exposure while changing focal lengths.

Small and Lightweight for Everyday Carry

Portability is one of the defining characteristics of this 20-40mm F2.8 standard zoom.

The A062 measures only 86.5mm in length, has a maximum diameter of 74.4mm and weighs just 365g. This compact design makes it easier to carry throughout the day and particularly well suited to travel, street photography and casual shooting.

TAMRON developed the lens to provide the benefits of a fast-aperture zoom without the size and weight typically associated with full-frame F2.8 zoom lenses.

Designed for Both Photography and Video

The A062 was designed not only for still photography but also for modern video applications.

Its 20-40mm range can be useful for vlogging, family videos, travel videos and other online content. The wide 20mm setting provides enough room to frame yourself or multiple subjects, while the 40mm end offers a more conventional perspective.

The lens also uses a zoom ring with a rotation arc of approximately 65 degrees, allowing rapid changes in focal length when recording or photographing fast-changing scenes.

Fast and Quiet VXD Autofocus

The 20-40mm F2.8 A062 uses TAMRON’s VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism.

VXD is designed to provide fast, precise and quiet autofocus, making it useful for both still photography and video recording.

The autofocus system is also compatible with camera-specific functions including Fast Hybrid AF and Eye AF on supported Sony cameras.

Close-Focusing Capability at 20mm

The lens provides impressive close-range performance for a standard zoom.

At the 20mm wide end, the minimum object distance is just 0.17m, with a maximum magnification ratio of 1:3.8. At 40mm, the minimum object distance is 0.29m with a maximum magnification ratio of 1:5.1.

This makes the A062 capable of producing dramatic wide-angle close-ups, allowing photographers to move close to a subject while still including a large amount of the surrounding environment.

High Image Quality in a Compact Body

The optical construction consists of 12 elements in 11 groups and is designed to provide high image quality throughout the zoom range.

With a diagonal angle of view ranging from 94°30′ at 20mm to 56°49′ at 40mm, the lens provides a substantial change in perspective while maintaining a relatively small physical footprint.

The nine-blade circular diaphragm also contributes to smooth rendering when shooting with the aperture opened up.

Practical Features for Everyday Shooting

The A062 includes several features designed for regular outdoor and travel use.

A 67mm filter diameter matches the filter size used by many other TAMRON mirrorless lenses, making it easier for photographers who already own compatible filters to share accessories between lenses.

The lens also features moisture-resistant construction and a fluorine coating, providing additional protection when shooting in changing outdoor conditions.

TAMRON Lens Utility Compatibility

The A062 is compatible with TAMRON Lens Utility, allowing users to customize supported lens functions and perform firmware updates.

This provides additional flexibility for photographers and videographers who want to configure the lens for their particular shooting style.

The lens was designed with video creators in mind, making its customization and firmware-update capabilities useful for vlogging and other content-production applications.

Sony E-Mount Full-Frame Compatibility

The 20-40mm F/2.8 Di III VXD (Model A062) was developed specifically for Sony E-mount full-frame mirrorless cameras.

The lens was announced on September 29, 2022, with a planned launch date of October 27, 2022.

Its compact dimensions and 365g weight make it particularly attractive to Sony photographers who want a lightweight everyday zoom while retaining a bright F2.8 aperture.
