Stabilizer (OS). Zoom range covers

frequently used focal lengths to handle

everything from snapshots and portraits

to sports action and macro photography.

get as close as approximately 4.7 cm

to your subject (from the front of the

lens). ELD glass and aspherical lens

elements correct aberrations to deliver

high image quality throughout the entire

zoom range. Sigma's Super Multi-Layer

Coating minimizes flare and ghosting.

HSM provides fast and quiet auto-

focusing.

An ultra-wide-angle zoom lens that

is ideal for capturing the grandeur

of landscapes and creating a strong

SLD glass and aspherical lens

elements deliver high image quality

throughout the entire zoom range.
