Tamron has introduced a lightweight wideangle zoom lens and upgraded two favourites. Compatible with the Nikon AF-D, Canon AF and Konica Minolta AF-D mount, the new SP AF 17-50mm f/2.8 XR Di II LD Aspherical (IF) lens is designed for use with APS-C digital SLRs. The focal length is equivalent to 26-78mm in a 35mm camera, which is wider than standard lenses. The lens has a maximum magnification ratio of 1:4.5, focusing as close as 27cm from the subject throughout the entire zoom range. Constructed from 16 elements in 13 groups, Extra Reflective Index (XR) glass minimises aberrations as well as optimising the distribution of optical power. To compensate for chromatic aberrations the lens includes a Low Dispersion element, while two hybrid aspherical elements maintain performance. Internal Surface Coating reduces the effect of ghost and flare. Available in May, the lens includes a flower-shaped lens hood, zoom lock mechanism and enhanced zoom ring patterns. Both the AF 28-200mm zoom and 70-300mm telephoto zoom lenses are now available in Tamronís Digitally Integrated (Di) series. Suitable for use with digital and film SLRs, the 28-200mm lens is available in May and has a minimum focusing distance of 49cm throughout the zoom range. The 70-300mm lens has a macro switch that enables it to focus 95cm from the subject, when the focal length is between 180-300mm. Both lenses are compatible with Nikon AF-D, Canon AF, Konica Minolta AF-D and Pentax AF mounts. Find out more by calling 01628 674411 or logging onto www.intro2020.co.uk
