Sigma's updated 120-300mm F2.8 EX DG OS APO HSM lens is now available in the US for $4700. This "splash-proof" telephoto zoom lens is geared toward sports and wildlife photographers in need of a generous telephoto range and a fast f/2.8 aperture. Its weather-resistant construction includes O-ring sealing connections to prevent dust and water damage.
The 120-300mm lens utilizes Sigma's HSM Hyper Sonic Motor for quieter focus. Containing 23 elements in 13 groups, the lens offers low dispersion glass elements in an effort to reduce chromatic aberrations. Visit Sigma's website for more information or to find a dealer.
