Fast F2.8 standard zoom for Sony full-frame mirrorless cameras covers 20-40mm and offers class-leading compact size and light weight
Starting from 20mm at the ultra wide-angle end and covering up to 40mm in the standard focal range, this lens is an unparalleled new fast-aperture standard zoom. 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 3.4” and 12.9 oz. with 67mm filter size. 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. Ideal for great for still photography and for creating vlogs and other video content. Provides exceptional close-up shooting with a 6.7” and 1:3.8 max. mag. ratio at the wide end.

An unprecedented compact and lightweight design
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 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.
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. When shooting landscapes, you can enjoy the wide-angle field-of-view and dynamic performance that only an ultra wide-angle lens delivers. 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. 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.
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.
Zoom ring rotates just 65° for rapid operation
The arc of rotation of the zoom ring is only 65°. This enables swift adjustment to the desired focal length with minimal movement.
New sculpted shape
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.
Improved texture and scratch resistance
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.
A 9-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.
TAMRON has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment. Also, the Connector Port is the water-proofed USB Type-C variety.
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture, and fingerprints.
