Super-Wide Zoom for APS-C Sony DSLRs

The Sigma 10-20mm f/4-5.6 EX DC HSM covers a 10-20mm focal range on Sony Alpha DSLR bodies such as the A100, A200, A300, A350 and A700. Its DC designation matches the image circle to APS-C sensors, making it a dedicated wide-angle tool for landscape, architecture and interior photographers who need an expansive field of view.

HSM autofocus with full-time manual override

The built-in Hyper-Sonic Motor delivers fast, quiet autofocus while allowing immediate manual focus adjustments without switching modes. An internal focusing system keeps the front element stationary, so circular polarising filters can be rotated freely and the lens length stays constant during focus travel, simplifying use on tripods or in tight spaces.

Optical design controls distortion

Three aspherical elements correct barrel distortion across the zoom range, while three SLD glass elements suppress chromatic aberration at the edges. The variable f/4-5.6 aperture maintains consistent exposure behaviour throughout the 10-20mm span, and the lightweight construction reduces fatigue during extended handheld shooting sessions.

Questions about this item

How close can the 10-20mm zoom focus while I keep shooting?

The internal focusing system keeps the front element stationary so the minimum focus distance does not extend as you zoom, letting you stay close to the subject throughout the range.

Will the Hyper-Sonic Motor stay quiet and cool during a full day of event coverage?

HSM drives the focus group ultrasonically with low mechanical friction, so the motor runs silently and generates minimal heat even under continuous operation.

Which camera bodies must I already own for this A-mount lens to function?

It mounts directly on Sony Alpha DSLR models A100, A200, A300, A350 and A700 without an adapter.
