TAMRON 28-300mm f/3.5-6.3 Di VC PZD
Tamron’s All-In-One™ Zoom Lens Evolution Continues Announcing An Exceptional New Lens For Full-Frame DSLRs
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.
State-of-the-art optical design technology delivers superior image quality
Focal length: 28mm Exposure:F/9 1/250 sec ISO:200
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.
Three Molded-Glass Aspherical elements incorporated in advanced optical design
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.
UXR glass element with greater refractive index than XR used for the first time.
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.
Four LD glass elements used in this advanced optical design
LD glass elements are positioned as the second and third elements in the first group to reduce chromatic aberrations at the telephoto end of the zoom range.
Effects of the LD glass elements would be even more effective if they were placed in the front group, but that would have required larger elements, thus making it much more difficult to achieve consistent quality in production. Even so, top-quality glass elements are used in abundance to achieve the best possible image quality over the entire focal range resulting in a versatile zoom lens suitable for a wide range of subjects.
Focus on portability
The lens is now even smaller and lighter
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.
Upgraded cosmetic design Elegant tungsten silver brand ring
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.
Powerful 10.7x all-in-one™ zoom provides incredible shooting flexibility
The lens covers an extended zoom range from 28mm wide-angle, to normal, to 300mm telephoto. It is a lightweight compact lens great for day-to-day use.
Circular diaphragm facilitates achieving spectacular blur effects
Using a nearly circular diaphragm makes it easy for users to achieve spectacular background blur effects that enable creative use of depth of field.
Advanced anti-reflection coating
The application of BBAR (Broad-Band Anti-Reflection) coatings for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting to deliver sharp, crisp, high-contrast images.
Moisture-resistant construction for outdoor shooting
Moisture-resistant construction helps prevent moisture from penetrating the lens.
PZD (Piezo Drive) delivers faster, quieter autofocus action
The PZD (Piezo Drive) provides noticeably faster, quieter autofocus action, allowing users to capture spontaneous moments in crisp images and to continue to shoot even when quiet operation is required. The full-time manual focus system enables fine focus adjus™ents to be made during autofocus shooting without having to change the focus mode beforehand.
VC (Vibration Compensation)
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.

*Length and weight are based on figures for the Nikon-mount lens.
*1. Length is the distance between the front tip of the lens and the mount face.
*2. This circular diaphragm retains a nearly circular shape even at two stops down from its maximum aperture.
*3. The Sony mount model does not include VC, since the bodies of Sony DSLR cameras include built-in image stabilization functionality.
