With a focal length range of 18-400mm and 22.2x zoom, it has an ultra-telephoto range equivalent to 620mm in the 35mm format. This brings distant subjects closer, while providing perspective-flattening effects that are only possible with an extreme telephoto lens. Plus it offers exceptional optical performance across the entire zoom range-from wide angle to ultra-telephoto. With this new lens - and its moisture-resistant construction - Tamron brings the art of photography to the joy of travel. Now you can use the same lens to shoot everything from stunning landscapes and neon-lit cities to detailed portraits and delicate flora.
