Sigma 18-35mm f/1.8 DC HSM Art (EF)

The Sigma 18-35mm f/1.8 DC HSM Art is a fast standard zoom for APS-C and Super 35 sized sensors, in Canon EF mount. It holds f/1.8 through its whole zoom range, which was a first for a zoom lens.

A constant f/1.8 gives a shallow depth of field and good low-light performance while keeping the flexibility of a zoom, so one lens can stand in for several primes. The range is equivalent to roughly 27 to 52mm in full-frame terms, which suits documentary work, interviews and run-and-gun filming.

The aperture runs from f/1.8 to f/16. The construction uses four aspherical and five SLD elements with a super multi-layer coating, internal focusing and zooming, and a Hyper Sonic motor for autofocus. It is designed for APS-C sensors, so it does not cover full frame, and it mounts on Canon EF. It suits Canon EF bodies and adapted setups.
