Wide-Angle Zoom for Nikon DX

The Sigma 10-20mm f/3.5 EX DC HSM is a wide-angle zoom lens built for Nikon F-mount DX-format cameras. It covers an equivalent focal range of 15-30mm, making it suitable for landscape, architecture and interior photography. The constant maximum aperture of f/3.5 provides consistent exposure throughout the zoom range. An internal focusing system keeps the front element from rotating, which helps when using the supplied petal hood.

Constant f/3.5 Aperture and 82 mm Filter Thread

The fixed f/3.5 maximum aperture offers usable speed for indoor shooting and low-light conditions without needing to adjust exposure while zooming. The lens accepts 82 mm filters via its front thread. Minimum aperture reaches f/22 for extended depth of field. Close focusing down to 24 cm delivers a maximum magnification of 1:6.6 for detail work.

Optical Construction and Coating

The optical design uses 13 elements arranged in 10 groups to control distortion and aberrations across the 102.4 to 63.8 degree angle of view. A super multi-layer coating suppresses flare and ghosting in high-contrast scenes. The seven-blade diaphragm produces a rounded aperture for smoother background blur. The lens weighs 1.71 kg and features a bayonet-mount plastic hood that locks in a transport position.

Questions about this item

Will this 10-20mm f/3.5 lens cover the full frame of my older Nikon film SLR?

Vignetting will occur if the lens is used with 35mm SLR cameras or digital cameras with sensors larger than APS-C size, so it is designed for DX-format Nikon F-mount bodies only.

How can I verify the autofocus is functioning correctly after mounting the lens?

The HSM autofocus motor should drive focus silently and quickly; check that the focus distance scale moves smoothly from the 24 cm minimum focus distance through to infinity at both 10 mm and 20 mm zoom positions.

Does the box include an 82 mm filter or do I need to buy one separately?

The lens accepts 82 mm filters via its front thread; a filter is not included and must be purchased separately, while the supplied bayonet-type plastic tulip hood attaches directly to the lens barrel.
