The Tamron 18-270mm F/3.5-6.3 Di II PZD Lens for Sony is a 15x high power zoom lens designed exclusively for digital SLR cameras using the more compact APS-C image sensors. The focal length of this lens is equivalent to approx. 28-419mm in 35mm format. Designed as an "all-in-one" lens, it will meet almost all photographic opportunities without changing lenses.The addition of PZD (Piezo Drive) ultrasonic autofocus motor helps make this lens lighter, short and slimmer than any previous lens in this category, and provides faster, quieter auto-focusing.Three hybrid aspherical lens elements and two LD (Low Dispersion) glass elements are used to accomplish effective compensation of on-axis and lateral chromatic aberrations, a critical factor to enhance the optical quality in digital photography.Design has been improved by adding a gold-colored band between the focus and zoom rings to enhance the appearance and make it stand out as a Di II lens. The rubber patterns of the zoom and focus control rings have been improved at the same time to compliment the digital camera design style and to provide better handling.
