The Tamron 17-28mm F/2.8 Di III RXD Lens is a compact and lightweight ultra wide-angle zoom lens for Sony full frame mirrorless cameras and weighs just 420g. It has an overall length of just 99mm and with no barrel extension whilst focusing or zooming it's perfect for travelling. The 17-28mm zoom’s AF drive system is powered by the RXD (Rapid eXtra-silent stepping Drive) AF motor unit that enables it to deliver high-speed, high-precision and superbly quiet operation, making it suitable for shooting virtually noise-free video as well as still photographs.
The 17-28mm RXD offers a large F/2.8 aperture throughout the entire zoom range and delivers edge-to-edge high-resolution and contrast. The combination of ultra wide-angle focal length, large constant F/2.8 aperture and a Minimum Object Distance (MOD) of 19cm at the wide-angle end encourages richly expressive and creative photography in a multitude of scenarios.
Superb high resolution performance
The 17-28mm zoom’s optical design consists of 13 lenses in 11 groups, including three aspherical lens elements, two LD (Low Dispersion) lens elements and one XLD (eXtra Low Dispersion) lens element that has properties close to those of fluorite. Together they efficiently suppress chromatic and other aberrations. Additionally, Tamron’s legendary BBAR (Broad-Brand Anti-Reflection) Coating effectively reduces ghosting and flare. Leveraging camera functions, it provides excellent optical performance matching the latest high resolution image sensors from edge-to-edge throughout the entire zoom range. The combination of compact size and light weight plus high resolution performance lets users capture a wide variety of genre including landscapes, architecture and street photography.
Extreme close-up capability
The 17-28mm zoom focuses close. The MOD at the 17mm wide position is 0.19m / 7.5 in (the same as the 28-75mm RXD) and the maximum magnification ratio is 1：5.2. At the 28mm end, it achieves the maximum magnification ratio of 1:6 while reaching the MOD of 26cm. This remarkable performance allows users to create great wide-angle compositions that emphasize perspective.
RXD stepping motor unit
The AF drive incorporates a sensor that accurately detects the position of the lens while the RXD motor unit delivers optimized AF control. This achieves very fast and accurate autofocus operation, allowing users to maintain pin-sharp focus on continually moving subjects or when filming video. The exceedingly quiet operation is an important advantage because it virtually eliminates extraneous sounds during video recording. In addition, the compact configuration of the RXD AF drive system contributes to the unprecedented size and weight reduction.
Moisture-Resistant Construction and Fluorine Coating
Environmental seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or rain drops and afford Moisture-Resistant construction. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions. Also, the front surface of the lens element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, moisture or oily fingerprints, allowing for much easier maintenance.
