Product Features:
Focal length of 17-70mm for shooting in a broad range of situations
This versatile zoom lens lets you enjoy shooting in a multitude of genres, from wide-angle scenes to telephoto moments. With a focal length range of 17mm to 70mm (a full-frame equivalent of 25.5-105mm), this is the world's first fast-aperture F2.8 standard zoom lens for APS-C mirrorless cameras to achieve a 4.1x zoom ratio. It’s ideal for a variety of scenarios, from portraits and street snapshots, to landscapes and even close-ups.
Fast F2.8 aperture throughout the entire zoom range for Sony E-mount and FUJIFILM X-mount
The 17-70mm F2.8 maintains its fast F2.8 maximum aperture throughout the entire zoom range (unlike variable aperture lenses where the maximum aperture changes as you zoom). Thanks to the F2.8 and high optical performance, the 17-70mm F2.8 allows you to capture your subjects with clear details from wide-angle to telephoto. The three main advantages of a fast F2.8 aperture are: A) ability to shoot successfully in lower light levels, B) beautiful and dreamy bokeh, and C) better control of depth-of-field which is particularly useful when intentionally limiting depth-of-field to improve portraits by blurring the area behind the main subject. Structurally, the optical formula includes 16 elements in 12 groups. It was created in pursuit of superior optical performance, utilizing an effective allocation of two GM (Glass Molded Aspherical) lens elements and one aspherical hybrid lens element. The optical design ensures high resolution and high contrast not just in the center of the image but also in corners and at the edges.
TAMRON’s proprietary VC for stable photography and video shooting
The 17-70mm F2.8 utilizes TAMRON's highly regarded VC image stabilization system to maximize the inherent optical performance of the lens. It reduces the degradation of picture quality caused by minute camera shake that is likely to occur during hand-held shooting at slow shutter speeds under low-light conditions indoors or at dusk. When shooting video, image stabilization leveraging AI technology will automatically perform the best compensation for different shooting situations.
MOD of 0.19m (7.5 in) for amazing close-ups
This advanced lens focuses extremely close for a standard zoom lens for APS-C mirrorless cameras. The MOD is just 0.19m (7.5 in) at the wide-angle end and 0.39m (15.4 in) at the telephoto end. When shooting very close to the subject, the lens enables expressive imagery with highly blurred backgrounds, a feature unique to fast-aperture lenses. This allows you to create one-of-a-kind photos of a variety of subjects, from snapshots to portraits, landscapes, and even architectural photography. Close-up shots of your main subjects taken at the 17mm end maximize the unique perspective only true wide-angle lenses can deliver.
Compact, lightweight design is perfect match for APS-C mirrorless cameras
This lens was created through the uncompromising pursuit of portability optimized for use with APS-C Sony E-mount cameras. Even with the inclusion of high-performance VC, the 17-70mm F2.8 is extremely light weight and compact, with an overall length of just 119.3mm (4.7 in), maximum diameter of 74.6mm, and weight of 525g (18.5 oz)[3]. It is a very versatile lens for travel, where small bags are preferred, and is a great portable lens for daily use.
High performance autofocus system means you'll own every shooting opportunity
The AF drive on the 17-70mm F2.8 includes an RXD motor unit to help you stay focused on the action. RXD uses an actuator to precisely control the rotational angle of the motor, allowing it to directly drive the focusing lens without passing through a reduction gear. A sensor that precisely detects the position of the lens enables high-speed and accurate AF, which is ideal when shooting continually moving subjects or recording video. And with a focusing system that is both smooth and quiet, the 17-70mm F2.8 lets you shoot free from stress not worrying about the drive sound in a quiet environment.
Circular aperture to produce a smooth-edged bokeh
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.
Moisture-Resistant Construction protects your lens
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment.
Fluorine Coating for protection and safe cleaning
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.
BBAR Coating: Advanced anti-reflection coating
The application of BBAR (Broad-Band Anti-Reflection) Coating for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting to deliver sharp, crisp, high-contrast images.
