■■■2-Year Warranty Exclusive to the Tamron Online Store (1-Year Manufacturer Warranty + 1-Year Online Store Warranty)■■■ The 17-28mm F/2.8 Di III RXD (Model A046) is a large-aperture, ultra-wide-angle zoom lens for Sony E-mount cameras designed specifically for mirrorless cameras, combining exceptional portability with high image quality. Its compact size and lightness make it the smallest and lightest in its class, making it easy to carry and capture a wide variety of landscapes, from cityscapes and travel destinations to mountainous landscapes. The lens utilizes a generous amount of special LD (Low Dispersion) and XLD (eXtra Low Dispersion) lens elements to significantly reduce chromatic aberration, delivering superior optical performance despite its compact body. Furthermore, with a minimum focusing distance of 0.19m at the 17mm wide-angle end, it allows for close-up shooting that takes advantage of the unique perspective of an ultra-wide angle. The AF drive is equipped with a high-speed, precise stepping motor unit, RXD (Rapid eXtra-silent stepping Drive). In addition, it features a simple weather-resistant construction and a dirt-resistant coating, making it ideal for comfortable outdoor photography.
It will lighten your workload and take you to new vistas. We want you to use a large-aperture ultra-wide-angle lens more often on a daily basis. To that end, we focused on usability. By deliberately limiting the zoom range to 17-28mm, we achieved an astonishingly lightweight and compact design, measuring just 99mm in length and weighing just 420g. This lens's overall length remains constant as you zoom, ensuring stable operation during shooting. Furthermore, it boasts a small filter diameter of 67mm, a small size for a large-aperture ultra-wide-angle zoom. By sharing the same filter diameter as the 28-75mm F/2.8 Di III RXD (Model A036), a large-aperture standard zoom lens in the same series, you can use various filters, including PL filters, and lens caps. Despite its compact body, the Model A046 delivers uncompromisingly beautiful image quality. Its generous use of LD lens elements, a special glass material with anomalous dispersion properties, and XLD lens elements with properties similar to fluorite, thoroughly suppresses chromatic aberration and other aberrations. In addition, the lens surface is coated with BBAR (Broad-Band Anti-Reflection) for excellent anti-reflection properties, making it ideal for capturing images of sunsets and other glare.
This lens reduces ghosting and flare, which can easily occur when shooting in backlit conditions. Additionally, by utilizing camera functions*, it achieves high resolution performance compatible with the latest high-resolution cameras across the entire zoom range, capturing images right to the edges of the frame. Experience the impressive world of ultra-wide-angle photography. *Enable in-camera lens correction. The Model A046 achieves a minimum focusing distance of 0.19m and a maximum magnification ratio of 1:5.2 at the 17mm wide-angle end. Even at the telephoto end, it achieves a minimum focusing distance of 0.26m and a maximum magnification ratio of 1:6. The short minimum focusing distance allows you to get close enough to capture powerful shots. Not only can you take advantage of the perspective inherent to ultra-wide-angle lenses, making close subjects appear larger and distant subjects appear smaller, but you can also open the aperture to get closer and blur the background, achieving the shallow depth of field and soft expression possible with a large aperture. This lens will satisfy your expressive potential. The AF drive is equipped with a proprietary RXD stepping motor unit. RXD is an actuator that can precisely control the rotation angle of the motor, and it directly controls the focusing lens without using a reduction gear.
This, combined with a sensor that detects the lens position with high precision, enables fast and precise AF. Not only does it accurately capture moving subjects, it also demonstrates its capabilities in video shooting. It is also exceptionally quiet, making it ideal for indoor shooting and other situations where drive noise is a concern.
