Superior, reliable image quality with a universal lens
The lens construction features 16 elements in 12 groups. This includes three Molded-Glass Aspherical elements, one Hybrid Aspherical element, two LD (Low Dispersion) elements, one XR (Extra Refractive index) glass element, and one element of UXR (Ultra-Extra Refractive Index) glass, which has greater refractive index than XR. The full use of specialized glass elements in the design contributes to thorough compensation of optical aberrations. In addition, the use of the latest coating technology for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting and assures sharp, crisp, high-contrast images.

A further expansion of the imaging range
With a minimum focal length of 16mm (35mm film equivalent: 24.8mm) at the wide-angle end of the zoom range, and a maximum focal length of 300mm (35mm film equivalent: 465mm), this remarkable new lens provides a zoom ratio of approximately 18.8X.

Responding to requests from consumers who wanted to be able to photograph subjects with a wider viewing angle than is possible with conventional high-power zoom lenses, Tamron has begun developing a unique lens with a minimum focal length of 16mm. At the telephoto end, the maximum focal length has been increased to an impressive 300mm. Users of this new lens can enjoy unprecedented framing flexibility by easily adjusting the angle of view using the convenient zoom ring.

Using a new design approach to create an ultra-compact lens

The latest optical technology has been used to provide an expanded zoom range (compared to the B008) at both the wide-angle and telephoto ends, without necessitating the use of an oversized lens body. By employing UXR glass (which helps to reduce the size of the front lens diameter), an optimized layout of the Molded-Glass Aspherical elements, and adopting a 5-lens-group zoom system approach to provide enhanced design flexibility, the new lens embodies the fusion of state-of-the-art optical design, sophisticated mechanical design, and high-precision lens manufacturing technology, thereby attaining a compact size, an unprecedented zoom range, and superior image quality.

A minimum focusing distance of just 0.39 meters supports an extensive range of macro photography capabilities
The new lens provides a minimum focus distance of 0.39 m over the entire zoom range, with a maximum magnification ratio of 1:2.9. This makes it possible to get right up close to the subject of the photo to enjoy easy, stress-free macro photography.

PZD (Piezo Drive) delivers faster, quieter autofocus action
The PZD (Piezo Drive), an advanced standing-wave ultrasonic motor system, delivers faster, quieter, more precise AF action when the autofocus is engaged. There is enhanced support for contrast-detection AF capabilities, and focusing when in live-view mode has been made smoother. The new lens also features full-time manual focus, a function that was not provided by B008, making manual focusing more convenient.

Sharper images with VC (Vibration Compensation)
Tamron’s acclaimed VC (Vibration Compensation) mechanism is incorporated into the new lens. VC reduces image blur caused by camera shake to deliver significantly sharper images even when shooting handheld at long telephoto settings.
