Tamron is developing a new 28-300mm f/3.5-6.3 Di VC PZD zoom lens for 35mm full frame DSLR cameras. A prototype of the lens will be on display at the Tamron booth at the CP+ 2014.
The Tamron 28-300mm f/3.5-6.3 Di VC PZD lens features a Piezo Drive auto focus motor and Vibration Compensation technology (VC), a maximum reproduction ratio of 1:3.5, and a minimum focus distance of 0.49m and a 67mm filter thread. The lens has a design of 19 elements in 15 groups. The lens comes with a petal-shaped lens hood
The Tamron 28-300mm f/3.5-6.3 Di VC PZD lens will be available for Canon, Nikon and Sony mounts. Pricing and availability yet to be announced.

Tamron 28-300mm F/3.5-6.3 Di VC PZD Lens Highlights
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. Particularly impressive is the thorough compensation of chromatic aberrations at the telephoto end, yielding images of enhanced clarity and crispness.
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 compared to the existing Tamron 28-300mm (Model A20). These technologies are the fruit of Tamron’s more than 20 years of research and development in the high-power zoom lens 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.
Upgraded cosmetic design – Elegant tungsten silver brand ring
Tamron has upgraded the cosmetic design and finish of this lens to create a more sophisticated, high-end look in keeping with the demands of discerning full-frame DSLR users. Employing a sophisticated linear pattern rubber grip on the zoom and focus rings and an elegant tungsten silver name-brand ring, this newly designed model accentuates its visceral presence with understated elegance and class.
PZD (Piezo Drive) delivers faster, quieter autofocus action
The PZD (Piezo Drive), a standing-wave ultrasonic motor system, delivers faster, quieter, more precise action when the autofocus is engaged. The full-time manual focus system is easy and intuitive, enabling quick and convenient manual focus at any time.
VC (Vibration Compensation)
Tamron’s acclaimed VC (Vibration Compensation) mechanism reduces image blur caused by camera shake to deliver significantly sharper images even when shooting handheld.
Circular diaphragm facilitates achieving spectacular blur effects
Using a circular diaphragm, this lens achieves spectacular background blur effects that enable creative use of depth of field.
Moisture-resistant construction for outdoor shooting – Moisture-resistant construction helps prevent moisture from penetrating the lens.
