The AF 55mm-200mm f/4.5-5.6 is a macro lens from Tamron exclusively for use with digital SLRs. Weighing 300g, the lightweight lens has a small image circle ensuring compatibility with Canon AF, Konica Minolta AF-D and Nikon AF-D mounts. Constructed from 13 elements in 9 groups, the new optical design includes a Low Dispersion (LD) element to compensate for chromatic aberration, while ghosting and flare are kept to a minimum through Internal Surface Coatings. The lens enables a minimum focusing distance over the entire zoom range of 95cm and the nine-blade diaphragm construction is designed to produce natural blurred effects when needed. For better handling, Tamron has enhanced the zoom and focus controls. The 55-200mm f/4.5-5.6 lens costs £129.99 and is available from www.intro2020.co.uk. Call 01628 674411 for more information.
