The Tamron AF18-270mm f3.5-6.3 Di II VC lens offers digital SLR's (with an APS-C sized image sensor) a focal length equivalent to that of approx. 28-419mm on a 35mm camera.
The AF18-270mm Di-II is a high power zoom lens made for exclusive use with digital SLR cameras. It gives evern the most discerning photographer an outstanding focal range giving great results throughout. Such results are enabled with the aid of Tamron's 'Vibration Compensation' anti-blur system.
Tamron uses three hybrid aspherical lens elements and two LD (Low Dispersion) glass elements to achieve effective compensation of on-axis and lateral chromatic aberrations. These are critical factors that enhance the optical quality of digital photography.
Encorporated into the Tamron AF 18-270mm lens are measures to help minimise ghosting and flare. Also the addition of special multi-coatings help reduce reflections and increase light transmission. In essense these features help produce outstanding optical performance throughout the entire focal length of the lens.
It also rivals specialty macro lenses with a minimum focus distance of 49cm and a maximum magnification ratio of 1:3.5. At last, a high-powered, multi-purpose lens that really makes the most of digital photography. |
