The new 17-28mm F/2.8 Di III RXD (Model A046) is a large aperture, ultra wide-angle lens for Sony E-mount full-frame mirrorless cameras. Model A046 features a filter diameter of 67mm (astonishingly small for a full-frame, large aperture, ultra wide-angle zoom lens) as well as an unprecedented light weight of 14.8 oz. and diminutive length of 3.9 in.
This new telephoto lens features a compact and lightweight design, an ideal match for full-frame mirrorless interchangeable lens cameras and the 67mm filter diameter is the same as all other Tamron lenses in this series. Other features that support a great shooting experience include a Moisture-Resistant Construction helpful for outdoor shooting and Fluorine Coating for easy maintenance. In addition, the Model A056 is fully compatible with various camera-specific features including Fast Hybrid AF and Eye AF.
Despite covering a wide range of focal lengths, the lens is lightweight and compact, with a length of 117mm (4.6 in) and a weight of 575g (20.3 oz). Aside from day-to-day portability, the 28-200mm F2.8-5.6's lightweight and compact size make it especially convenient for travel photos, where users wish to avoid the burden of heavy baggage. Tamron has also taken an uncompromising approach to optical performance, making liberal use of special lens elements -- including LD (Low Dispersion) and XLD (eXtra Low Dispersion) -- to greatly suppress chromatic aberrations, and making it possible to achieve high image quality from edge to edge.
