Tamron RXD 17-28mm f / 2.8 Di III (Model A046), Wide Angle Wide Angle Lens for Sony FE Full-Size Hybrid Cameras
It has a filter 67 mm in diameter, weighs only 420 g and measures less than 10 cm long. The compact size of this lens offers an excellent balance with Sony's full-size hybrid cameras.
The A046 offers a large f / 2.8 aperture across the zoom range, high resolution, and high contrast on the edges of the image. Such a zoom lens with such a focal range, an aperture f / 2.8 and a minimum distance of 19 cm (in wide angle position) offers unique creative possibilities in a light and compact package.
The new zoom AF system is powered by an RXD (Rapid eXtra-silent stepping Drive) stepper motor that allows you to operate at high speed, with extreme precision and in a quiet way, making it perfectly suitable for shooting. of video.
The A046 is characterized by a moisture resistant construction and a fluorine coating that repels fingerprints and dirt. In addition, the model fully compatible with the various features specific to Sony FE: Fast Hybrid AF and Eye Focus.

1. Coupling with the 28-75mm f / 2.8 Di III RXD (model A036)
Sharing the same concept as the A036 launched in May 2018, the 17-28 mm zoom (model A046) was designed with the highest priority of high optical performance in a lightweight and compact package. Tamron engineers achieved unmatched size (99mm) and light weight (420g) for a focal length range of 17 to 28mm. The footprint is constant, which creates a stable and well-balanced operation and excellent mobility. In addition, the A046 model has a filter 67 mm in diameter, very small for an ultra-wide angle zoom. It has the same filter size as its predecessor, allowing the use of the same cap and filters. The two zooms combined form an extremely compact system that covers focal lengths ranging from 17 to 75 mm and weighing less than 1 kg (35.3 oz).
2. Beautiful optical performance
The 17-28mm optical zoom design includes 13 lenses divided into 11 groups, including three aspherical lenses, two Low Dispersion (LD) lenses, and an XLD (eXtra Low Dispersion) lens with properties similar to those of fluorite. Together, they effectively suppress chromatic and other aberrations. In addition, Tamron's legendary BBAR coating (anti-reflection) effectively reduces ghosting and reflections. Taking advantage of the camera's features, it offers excellent optical performance, compatible with the latest high-resolution, end-to-end image sensors across the entire zoom range. The combination of compact size and light weight as well as high resolution performance allows users to capture a wide variety of images
3. Close-up shot
The minimum focus at 17mm wide is 0.19m (same as A036) and the maximum magnification ratio is 1: 5.2. At 28 mm, it reaches the maximum magnification factor of 1: 6 and with a minimum focus of 0.26 m. This remarkable performance allows users to create compositions that emphasize perspective (the close subject is large and the subject remote, smaller) and are unique to the wide angle.
4. Silent RXD motorization
The AF system incorporates a sensor that accurately detects the subject's position while the RXD engine block moves smoothly. This allows for quick and accurate focusing for maximum sharpness on constantly moving subjects or when shooting video. Quiet operation is a significant advantage when recording video. In addition, the compact configuration of the RXD AF system contributes to the unprecedented reduction in size and weight.
5. All weather construction
Seals are located in the lens mounting area and at other critical locations to prevent the ingress of moisture and / or raindrops and to permit moisture resistant construction. This feature provides an extra layer of protection when shooting outdoors in adverse weather conditions. In addition, the front surface of the lens is coated with a fluorine compound which has excellent water repellency and oil repellency. The surface of the lens is easier to wipe and is less vulnerable to the harmful effects of dirt, moisture or greasy fingerprints, making maintenance much easier.
6. Uniform design and operation in all Tamron lenses for hybrid cameras for Sony FE
Similar to the 28-75mm (model A036), the 17-28mm (model A046) has a zoom ring on the front and a focus ring on the back. The zoom, focus and other functions are identical in this series to ensure consistent operation. The design is sleek and functional, it features the Luminous Gold ring carefully crafted, characteristic of the "Human Touch" Tamron and a metal rigid and elegant.
