17-70mm F/2.8 Di III-A VC RXD

    The Tamron 17-70mm f/2.8 Di III-A VC RXD is a 25.5-105mm-equivalent lens for APS-C-format mirrorless cameras, with a variable zoom range and a brilliant design. The wide-to-short-tele range is great for everyday shooting, and the fast f/2.8 constant maximum aperture is ideal for working in low-light situations and provides better depth-of-field control. A set of specialized optics, including aspherical and low dispersion components, complement this design, resulting in well-corrected imagery with exceptional sharpness, clarity, and color accuracy. Tamron's BBAR coating lowers flare and ghosting for enhanced contrast when operating in backlighting and harsh lighting environments.

    A focal length for 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 large-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

    The 17-70mm F2.8 maintains its large F2.8 maximum aperture throughout the entire zoom range (unlike variable aperture lenses that darken as you zoom). Thanks to F2.8 and high optical performance, 17-70mm F2.8 allows you to capture your subjects with clear details from wide angle to telephoto.
    The three main advantages of a large F2.8 aperture are:
    A) ability to shoot successfully in lower light levels
    B) beautiful and dreamy bokeh
    C) better control of depth-of-field

    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 frame but also in corners and at the edges.

    VC for stable photography and video shooting

    The 17-70mm F2.8 utilizes Tamron's highly regarded, proprietary 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 handheld shooting at slow shutter speeds under low-light conditions indoors or at dusk. When shooting video, by leveraging AI technology, image stabilization performance improves compared to conventional models.

    Focuses close

    This advanced lens focuses extremely close for a standard zoom lens for APS-C mirrorless cameras. The MOD (Minimum Object Distance) 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 large-aperture lenses.

    Compact, lightweight design

    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). It is a very versatile lens for travel, where small bags are preferred, and is a great portable lens for daily use.

    Superb AF keeps it sharp and quiet

    The AF drive incorporates an RXD (Rapid eXtra-silent stepping Drive) stepping motor unit. RXD uses an actuator that is able to precisely control the rotational angle of the motor, allowing it to drive the focusing lens without passing through a reduction gear.The addition of a sensor that detects the position of the lens to a high degree of accuracy enables high-speed and precise AF, which allows you to maintain razorsharp focus when shooting continually moving subjects or filming video. The lens is also remarkably quiet, eliminating concerns of drive sounds being picked up while shooting video
