28-300mm F/3.5-6.3 Di VC PZD, 19 Elements/15 Groups, 540 g, Nikon <b>Tamron's All-In-One Zoom Lens Evolution Continues Announcing an Exceptional New Lens for Full-Frame DSLRs</b>

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 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.

<b>State-of-the-art optical design technology delivers superior image quality</b>
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.

<b>Focus on portability. The lens is now even smaller and lighter</b>
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.

<b>Advanced anti-reflection coating</b>
The application of BBAR (Broad-Band Anti-Reflection) coatings for suppressing reflections on a lens element surfaces minimizes unwanted flare and ghosting to deliver sharp, crisp, high-contrast images.

<b>PZD (Piezo Drive) delivers faster, quieter autofocus action</b>
The PZD (Piezo Drive) provides noticeably faster, quieter autofocus action, allowing users to capture spontaneous moments to crisp images and to continue to shoot even when quiet operation is required. The full-time manual focus system enables fine focus adjustments to be made during autofocus shooting without having to change the focus mode beforehand.

<b>VC (Vibration Compensation)</b>
Tamron's acclaimed VC (Vibration Compensation) mechanism reduces image blur caused by camera shake to deliver sharp images even when shooting handheld in low light or at the telephoto end.

<b>Upgraded cosmetic design. Elegant tungsten silver brand ring</b>
Employing a sophisticated linear pattern rubber grip on the zoom and focus rings and an elegant tungsten silver brand ring, this newly-designed model accentuates its visceral presence with understated elegance and class.

<b>Circular diaphragm facilitates aqchieving spectacular blur effects</b>
Using a nearly circular diaphragm makes it easy for users to achieve spectacular background blur effects that enable creative use of depth of field.

<b>Moisture-resistant construction for outdoor shooting</b>
Moisture-resistant construction helps prevent moisture from penetrating the lens.
