28-300mm F3.5-6.3 Di PZD
State-of-the-art optical design technology delivers superior image quality
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 ... not available in A-mount).
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.
Circular diaphragm facilitates achieving spectacular blur effects
Using a circular diaphragm*4, 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.
