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
Broad-Brand Anti-Reflection Coating: 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
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
Moisture-Resistant Construction: The lens comes sealed near the mount area and other critical locations that protect its optical elements from moisture and rain drops
