Despite a compact, lightweight design that makes it highly portable, this lens includes a newly developed image stabilization mechanism. The IS provides camera shake compensation up to an equivalent of approximately four full shutter speed steps*1, enabling natural looking photos in dim environments under existing light. Tack-sharp images and a 0.25m/9.8inch minimum shooting distance are maintained over the entire zoom range. Flare and ghost are minimal, and the circular aperture produces beautiful background blur effects. Also featuring high-speed autofocus, this IS zoom lens is an excellent choice as ?standard? lens. NOTE: Can only be used with digital SLR cameras that support EF-S lenses.
