- Optical design
The 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.
- Smaller and lighter
The new optical design facilitated downsizing of the lens body, leading to a smaller overall lens when compared to the existing Tamron 28-300mm (Model A20).
- New 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.
- PZD (Piezo Drive) for fast, quiet autofocus
The PZD (Piezo Drive), a standing-wave ultrasonic motor system, delivers faster, quieter, more precise autofocus.
- VC (Vibration Compensation)
The lens comes with Tamron’s version of image stabilisation: VC (Vibration Compensation).
- Moisture-resistant construction
The construction of the lens helps to prevent moisture from penetrating the lens.
