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.
Compatible with TAMRON Lens Utility™ software
The 20-40mm F2.8 is compatible with the dedicated TAMRON Lens Utility software (for PC/ for devices with Android™  OS) that was developed in-house by TAMRON. TAMRON Lens Utility will let users customize focus ring settings and update to the latest firmware when necessary.
