August 25, 2004: Tamron has released a new extended range 28-300mm zoom lens that is compatible with both film and digital SLR cameras.
Marketed under the name, Tamron AF28-300mm F3.5-6.3 XR Di Aspherical (IF) Macro (Model A061), it is the smallest and lightest currently available lens in its class. The Di design incorporates a special multi-coating that reduces this sensor-induced ghosting and flare and the 10.7x zoom range provides a 35mm equivalent focal length range of 43-465mm when the new lens is fitted to a DLSR with a 1.5x lens multiplier factor. The new lens focuses down to 49 cm from the subject through its entire zoom range, providing genuine macro focussing (with no need to switch modes) plus extreme telephoto capability. Constructed from four types of optical glass – including XR (Extra Refractive index) and LD (Low Dispersion) elements – it consists of 15 glass elements in 13 groups, with a nine-blade diaphragm controlling image aberrations, especially in highlights. A flower shaped lens hood comes as a standard accessory.
