Sigma launches 18-250mm DC OS HSM lens: "
Sigma has announced the 18-250mm F3.5-6.3 DC OS HSM superzoom lens. Offering a 13.9x zoom range in a body only slightly longer than the company's current 18-200mm F3.5-6.3 OS lens, this new model features an optical design of 18 elements in 14 groups, including four Special Low Dispersion elements and three aspherical elements to minimise aberrations. Designed for use on cameras with APS-C / DX sensors, the lens is expected to be available from March, for Sigma, Nikon, Canon, Pentax and Sony mounts."
