The 70-200mm F/2.8 complements the extremely successful concept of the Tamron 28-75mm F/2.8 and extends the focal length range to 200mm. Particular attention was placed on top quality combined with high luminosity and compactness as is the case with the award-winning 28-75mm and * SP lenses in general.
In spite of its compact construction, the 70-200mm is packed full of features, which permit creative picture taking in all situations. The professional image quality also does justice to demanding photographers. Extreme sharpness, resolution and brilliance are its trademarks. Moreover, it is the best of its class in the categories minimum focus distance (only 0.95 m in the entire focal length range) and a magnification ratio of (1:3,1).
When using full frame cameras the medium tele-range of 70 mm to 200 mm is completely covered. When used together with APS-C sized cameras, the lens offers an equivalent of 109 mm to 310 mm arises (referring on the angle of view of the full frame) **. Whether for nature, sport or people-photography, the extraordinary optical performance will inspire you.
* SP (super performance) high-capacity lenses of excellent optical and mechanical quality.
** Tamron uses a factor of 1.55 for the conversion to full frame.
The designation “Di” (Digitally Integrated Design) marks a generation of lenses, which have been specially adapted to the higher requirements of digital SLR cameras (APS-C and full frame).
Delivering leading-edge image quality
The optical design of this lens uses a high-performance XLD (Extra Low Dispersion) element, which is manufactured out of a special glass with an extremely low refractive index. The refractive index describes the ability of the lens to split a light beam into its spectral colours. The dispersive properties are even lower than standard LD lenses and are at a level similar to fluorite. The XLD lens in combination with the LD element delivers the highest contrast and brilliance. This effectively prevents the problem of chromatic aberration in telephoto photography and delivers a high level of sharpness even in the peripheral regions. The result is a lens that effectively compensates for axial chromatic aberration and magnification aberration throughout the entire zoom range and guarantees the highest resolution and brilliance for your pictures.
Tamron's Super Performance series delivers a range of lenses that meet the highest standards.
LD (Low Dispersion)
Lens element for greater image sharpness and the correction of chromatic aberration.
Internal Focusing (IF) System
The extension length of the lens does not change during focussing and the close focussing distance is significantly reduced across the entire focusing range.
