Tamron 28-300mm F/3.5-6.3 Di VC PZD Lens for Sony A

Since the launch of its first versatile high-performance, high-power zoom, the 28-200mm ( Model 71D ) in 1992, Tamron has continued to expand its long-range zoom portfolio. In response to the growing popularity of full-frame digital SLR cameras, Tamron is now launching a new, full-frame, high-power zoom incorporating PZD ( Piezo Drive ), a standing-wave ultrasonic motor system optimized for swift, quiet autofocus, along with the acclaimed VC ( Vibration Compensation ) mechanism plus a new upscale cosmetic design and finish.

This all-in-one™ 28-300mm lens delivers superb image quality in a remarkably compact, lightweight package, and is the fruit of Tamron's program of extensive technological development over the years.

The advanced optical construction of this lens includes four elements of LD (Low Dispersion) glass, three Molded-Glass Aspherical elements, one Hybrid Aspherical element, 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 its design contributes to making this outstanding lens as compact and lightweight as possible, while minimizing aberrations, resulting in superior image quality.

Through the effective application of aspherical technology, one lens element can take the place of multiple elements without compromising performance.This is what allows us to produce remarkably compact long-range lenses that deliver a uniformly high level of image quality at all focal lengths and apertures. Molded-Glass Aspherical elements reduce aberrations particularly well when employed as the first element in the second group.Moreover, making elements thinner and reducing the front element diameter contribute to achieving more compact lenses.

Molded-Glass Aspherical elements require high-level manufacturing technologies, and larger elements are more difficult to produce, but we have refined these technologies to yield outstanding results.

No matter how high-performance the lens is, it won't satisfy requirements as a lens suitable for day-to-day use if it is overly large and heavy. With this all-in-one™ zoom lens, Tamron worked to achieve impressive compactness while endowing it with high imaging performance and enhanced operability with features such as upgraded autofocus.

For that reason, this lens also incorporates a UXR (Ultra-Extra Refractive Index) glass element with a greater refractive index than even the XR glass elements that contributed to the compactness of previous Tamron all-in-one™ zoom lenses.Placing a UXR glass element at the front of the lens achieves a smaller front lens diameter. In addition, placing an XR glass element at an optimal location allows the lens to be lighter and more compact than the existing Tamron 28-300mm (Model A20) lens.

In addition to state-of-the-art optical design that facilitates downsizing of the lens body, the mechanical design, which incorporates a highly sophisticated multi-stack-cam layout that takes up far less space, and PZD (Piezo Drive), an autofocus drive system with a simpler, more compact structure, has made it possible to reduce the overall dimensions of this lens.
