Sigma 18-35mm F1.8 DC HSM
Lens for Nikon:
Sigma 18-35mm F1.8 DC HSM Lens is a wide-angle to normal-length zoom lens that
features a fast, bright constant f/1.8 maximum aperture. It is specifically
designed for use with APS-C-sized sensors and provides a 35mm-equivalent focal
length range of 27-52.5mm. The lens integrates four aspherical elements into its
construction as well as five Special Low Dispersion (SLD) glass elements to help
minimize various aberrations and distortions throughout the zoom range as well
as provide greater image sharpness and clarity. A Super Multi-Layer Coating has
also been applied to lens elements to reduce surface reflections, lens flare,
and ghosting to produce images with higher contrast and color fidelity.
The lens barrel design is constructed from a Thermally Stable Composite (TSC)
material that is akin to metal in texture and resistance to temperature and
environmental changes while also remaining lightweight and compact. An internal
focusing and zooming mechanism also helps to maintain a compact and consistent
overall length and non-rotating front ring also better enables the use of
circular polarizing filters. For control of focus, a Hyper Sonic Motor (HSM) is
used to ensure fast, precise, and quiet focusing capabilities that are well
suited to continuous shooting and movie recording.
