Sigma 18-35mm f/1.8 DC HSM Lens for Canon APS-C DSLRs (Renewed)

Meet a versatile fast-aperture zoom that covers wide angle to standard for Canon APS-C bodies. The Sigma 18-35mm f/1.8 DC HSM lens delivers an unusual combination of range and brightness, offering creative possibilities from sweeping landscapes to intimate portraits. Designed specifically for APS-C sensors, this lens translates to a 27-52.5mm equivalent on full-frame terms, making it a natural daily go-to for photographers who value speed and flexibility in a single lens.

What sets it apart is the constant f/1.8 maximum aperture across the zoom range. That brightness helps separate subjects from backgrounds, allows better low-light performance, and invites more expressive depth of field. The internal focusing and zooming design keeps the length constant while you frame, which adds to handling and balance when shooting handheld or on a tripod.

Key design and engineering details include a wide glass molded aspherical element and Special Low Dispersion glass to combat aberrations and curvature at the wide end. Thermally stable composite materials help reduce size and weight without compromising accuracy. The lens also supports the USB Dock for customization and compatibility with SIGMA's Global Vision ecosystem.

In terms of focusing and rendering, the Hyper Sonic Motor (HSM) delivers smooth, fast, and quiet AF, which pairs well with modern camera bodies for both stills and video. A 9-blade rounded diaphragm creates pleasing background blur, while a minimum focusing distance of 28 cm keeps close-up opportunities within reach. The lens accepts 72 mm filters, broadening the range of creative choices for landscapes and portraits.
