This is a telephoto zoom lens that has a large maximum aperture of f/2.8 which remains
constant throughout the zoom range. It also offers an excellent
"close-focusing-distance" minimum of just 3.1' (0.95 m) throughout its entire
zoom range, with a maximum macro magnification ratio of 1:3.1 at f=200mm. When
mounted on an APS-C sensor size digital SLR camera, it provides a focal length
equivalent of 105-300mm.
Di (Digitally Integrated Design) is a designation Tamron puts on
lenses featuring optical systems designed to meet the performance
characteristics of digital SLR cameras. Features like LD glass elements and
Internal Focusing put this lens in the same category as the much bigger and more
expensive professional Tamron lenses.
