The Tamron 17-28mm f/2.8 Di III RXD Wide-Angle Zoom Lens was designed with the top priority of high optical performance in a form factor that is light and compact. Tamron engineers have achieved an unrivalled small size and light weight for a zoom range of 17-28mm. The overall length does not change when zoomed or during focus, thereby creating stable, well balanced operation and excellent mobility. In addition, the lens features a filter diameter of just 67mm, very small for an ultra-wide-angle zoom lens.
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 casual snapshot photography.
Extreme Close-Up Capability
The 17-28mm zoom focuses close. The MOD at the 17mm wide position is 7.5 in (same as Model A036) 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 10.2 in.
