Today, Sigma announced a new super-range zoom lens, the 18-250mm F3.5-6.3 DC OS HSM. The new Sigma 18-250mm F3.5-6.3 DC OS HSM will be available in March 2009 in Canon, Nikon, Pentax, Sony and Sigma mounts.
The combination of optical stabilization (OSM) and the hypersonic motor (HSM) makes this lens very attractive as a consumer-level all purpose lens. In my opinion, Canon really botched the opportunity to make solid super-zoom lens with its new EF-S 18-200mm IS lens by failing to put a USM motor inside it, which has resulted in a slower and noiser autofocus. If the price is right, perhaps this Sigma 18-250mm lens can fill that void with a fast focus speed and optical stabilization.
