NEW SIGMA 18-250MM F3.5-6.3 DC MACRO OS HSM LENS

Sigma Corporation of America announces the new 18-250mm F3.5-6.3 DC Macro OS HSM lens, which offers a more compact size, macro capability with a maximum magnification ratio of 1:2.9 and the use of Thermally Stable Composite (TSC) material. Often compared to polycarbonate, TSC has a high degree of elasticity and exhibits little variation in its structure in extreme temperature conditions. Features include double-sided aspherical lenses and an approximate 13x high zoom ratio with a filter size of 2.8 inches in diameter. Sigma’s unique OS system, as well as one Special Low Dispersion (SLD) glass and three aspherical lens glasses, compensate for camera shake and enable correction of color aberration, respectively. The new macro lens is also equipped with Super Multi-Layer Coating to reduce flare and ghosting, a Hyper Sonic Motor (HSM) to ensure fast and quiet autofocusing, and a rounded, seven-blade diaphragm to create an attractive round blur to the out of focus areas.
