Adorama offers the Sigma 18-200mm f/3.5-6.3 DC OS Autofocus Optical Stabilized Lens for Canon, model no. 888101, for $349. With free shipping, that’s the lowest total price we could find by $10, although we listed it for $26 less in May, since expired. It features an 11x optical zoom, two hybrid aspherical lenses, lens coating (to reduce flare and ghost effects), and more. It’s designed for use with most Canon digital SLR EF-mount cameras.
