Sigma 18-250mm f/3.5-6.3 DC Macro OS HSM

Rating: no rating

By revolutionising the optical and structural design of the Sigma 18-250mm F3.5-6.3 DC OS HSM, this new lens achieves a compact size and a minimum focusing distance of 35cm. Sigma’s newly developed material, Thermally Stable Composite (TSC), which maintains its structure and has little contractility especially in varying temperatures, is incorporated into the lens barrel. Its small size and huge focal-range make it perfect for travel photographers and those who like to keep equipment down to a minimum.
