Wide-angle zoom for APS-C SLRs

The Sigma 10-20mm f/4-5.6 EX DC J is a super wide-angle zoom designed exclusively for Pentax digital SLR cameras with APS-C sensors. Its 10-20mm focal range provides an approximate equivalent field of view of 1530mm on these bodies. The compact, lightweight construction matches the smaller sensor format for balanced handling.

Bundle accessories expand creative

The included filter kit enables immediate use of polarising or graduated filters, aided by the lens's non-rotating front element. A dedicated lens hood reduces flare in expansive landscapes, while the pouch and case protect the optic during transport. Cleaning tools and a cap keeper maintain readiness for indoor architecture or outdoor scenes.

Variable aperture and mount constraints define

The maximum aperture narrows from f/4 at 10mm to f/5.6 at 20mm, restricting low-light performance and depth-of-field control at the long end. Autofocus relies on the camera body's drive motor, so focus speed varies with the specific SLR used. The DC designation confirms incompatibility with full-frame Pentax bodies, limiting use to APS-C formats.

Questions about this item

Will the lens hood, caps or filter kit in the bundle need replacing after regular use?

The bundle includes a lens hood, caps, filter kit and cleaning kit; these accessories are consumables that may wear or get lost over time and can be replaced individually.

What optical limit appears first when shooting wide open at the 20 mm end?

At 20 mm the maximum aperture is f/5.6, so depth of field control and low-light capability are the primary limits before diffraction or aberration become noticeable.

Does the internal focusing motor make the lens noisy or warm during all-day shooting?

The internal focusing system keeps the front element stationary and operates quietly; no heat or noise issues are reported for extended use.
