Product features

  1. The 2nd large-diameter series for Sony E mount compatible with full-size mirrorless single-lens camera. Lightweight, compact design super wide-angle zoom with emphasis on practicality
    Model A046 has been popular with many customers since its release in May 2018. The frequently used zoom lens of the 28-75 mm F / 2.8 Di III RXD (Model A036) (hereinafter referred to as Model A036) That’s why we have developed the concept of “compact”. Designed to be smaller and lighter than anything while maintaining high optical performance. By setting the zoom range to a focal length of 17 to 28 mm, we achieved an overwhelmingly small and lightweight unit with a length of 99 mm and a mass of 420 g. In addition, since the overall length does not change at the time of zooming and the operability at the time of shooting becomes stable, the balance with the compact camera body is also good, and it is excellent in mobility. In addition, a filter diameter of 6767 mm and an ultra-wide-angle zoom are achieved with an extremely small filter diameter. As the filter diameter is the same as Model A036, lens caps, PL filters, ND filters, etc. can be used in common, making it possible to build a very compact system by using it in conjunction with Model A036.

  2. High resolution performance designed without compromise
    Lens constitution is 11 groups 13 pieces. In addition to three aspheric lenses, two special glass materials LD (Low Dispersion: anomalous low dispersion) lenses that have anomalous dispersion to light, and an XLD (eXtra Low Dispersion) lens that is more effective and has characteristics similar to fluorite We use a total of three pieces of luxury, and effectively suppress various aberrations including chromatic aberration. In addition, the adoption of BBAR (Broad-Band Anti-Reflection) coating that boasts high anti-reflection performance significantly reduces the occurrence of ghosts and flares. In addition, by utilizing the camera functions *, high resolution performance compatible with modern high-pixel digital cameras is demonstrated at the center, as well as near the center, from the wide-open aperture to the periphery of the screen. The combination of small size, light weight and high resolution performance makes it easy to enjoy photography in various fields such as architecture and snaps as well as landscapes.
    * Turn on the in-camera lens correction function and enjoy shooting.

  3. High close-up shooting ability to broaden the expressive power of super wide-angle zoom
    At 17mm wide-angle end, it achieves amazing close-up shooting ability with 0.19m, which is highly appreciated by Model A036, and can capture the subject with a maximum magnification of 1: 5.2 and a high magnification. In addition, while maintaining the shortest shooting distance as short as 0.26 m at 28 mm at the telephoto end, the maximum shooting magnification has achieved 1: 6. This makes it possible to enjoy the expression typical of a wide-angle lens with a sense of perspective, such as a close subject with a larger image and a far object with a smaller image.

  4. Equipped with stepping motor unit “RXD”
    The AF drive is equipped with a sensor that detects the lens position with high accuracy, and a stepping motor unit RXD optimized for AF control. It achieves extremely fast and precise AF operation, and it is possible to accurately focus on moving object shooting and movie shooting where the subject continues to move. In addition, it is also characterized by the fact that the driving sound of the lens is difficult to record at the time of movie shooting because of its excellent quietness. The RXD contributes to the compactness and lightness of the entire lens, as the AF drive system can be made compact.

  5. Simple drip-proof, anti-soiling coat to support comfortable shooting
    Seals for drip-proof are placed at major parts such as the movable part and the joint part of the lens barrel, making it difficult for water to enter the inside of the lens. In addition, the front of the lens is equipped with an anti-fouling coating technology with a fluorine compound that is excellent in water and oil repellency. Water drops, oil from your hands, etc. are easy to wipe off and maintenance is easy.

  6. Consistent operability and design with large aperture zoom series for full size mirrorless
    The Model A046 has the zoom ring in front and the focus ring in the same way as the Model A036, and the direction during zooming and focusing is also aligned with the Model A036. Therefore, we take care not to break the shooting tempo with a consistent operability throughout the series. In addition, it has a design with a high degree of perfection, such as a form closely nestled in the internal structure, a thinly decorated Luminous gold ring, and a metal mount with excellent precision and rigidity. In particular, Luminous Gold Brand Ring is designed to look like a TAMRON brand lens, even when attached to a single lens or camera.

  7. Shooting expression that spreads in combination with “28-75 mm F / 2.8 Di III RXD (Model A036)”
    Model A046 can be used in combination with Model A036 to cover the wide-angle to mid-telephoto range while securing the brightness of the open F / 2.8. In addition, from the good portability of less than 1kg, 970g together, also supports the free shooting that takes full advantage of the mobility of the mirrorless camera. Furthermore, since the filter diameter is the same as Φ67 mm, the lens cap removed at the time of lens replacement can be attached to the other side, supporting smooth lens replacement. In addition, it is possible to share PL filters, ND filters, etc., making it possible to build a highly compact, highly compact large-aperture system.

  8. Supports main camera functions
    ・ Fast hybrid AF
    ・ Pupil AF
    ・ Direct manual focus (DMF)
    ・ In-camera lens correction (peripheral light amount, magnification chromatic aberration, distortion aberration)
