14 to 150mm Di III all-in-one zoom lens. Introducing the first micro four thirds lens from Tamron. High-power all-in-one zoom in a choice of two colors. Developed by Olympus imaging and Panasonic, Micro Four Thirds is a new system standard for compact mirrorless interchangeable-lens cameras that enables users to capture high quality images using smaller, lighter equipment. Now, Tamron has expanded the possibilities of the Micro Four Thirds system with an innovative 14 to 150mm zoom lens (equivalent to 28 to 300mm in the 35mm and full-frame formats). This 10.7x zoom weighs only 285g (10.1oz) and has a compact form factor that accepts a 52mm diameter filter. Available in a sophisticated black and silver finish, this unique lens makes it easy to compose and capture sharp pictures over a very wide range of shooting conditions. It is ideal for travel, family and creative photography. The essence of Tamron technology in a compact, all-in-one zoom that minimizes aberrations and maximizes image quality. The optical design of this lens includes one LD (low dispersion) glass element, two AD (anomalous dispersion) glass elements, two molded-glass aspherical elements and one hybrid aspherical element. This formula reduces aberrations to a bare minimum to achieve exceptional class-leading image quality. The 14 to 150mm zoom is the fruit of Tamron's 20+ years of experience in designing and manufacturing world-class all-in-one zoom lenses. The stepping motor's actuator allows precise control of angular rotation, and since it drives the focusing mechanism directly without any intermediary reduction gear, it is also exceptionally quiet. These features also give the lens a seamless, fluid auto-focusing action when shooting video.
