The Sigma 18-35mm f1.8 DC HSM Lens is the first wide-angle to zoom lens (as of 22nd April 2013) to achieve a maximum aperture of f1.8 throughout the entire zoom range. The Sigma 18-35mm is a standard zoom lens that offers a focal range equivalent to 27-52.5mm in the 35m format. The 9 blade rounded diaphragm creates an attractive round bokeh at large-aperture settings, while the HSM (Hyper Sonic Motor) ensures a silent, high-speed AF. This lens incorporates a wide glass molded aspherical lens with Special Low Dispersion (SLD) glass to compensate for aberrations and curvature at the widest angle. Its new Global Vision design works with its compatibility with the Sigma USB dock for further customisation. Sigma's DC lenses are designed for cropped sensors and the image circle on this lens is designed to match the smaller size of the image sensor on small-frame sensor cameras (DX-format on Nikon and EF-S on Canon). The lens is ideal for landscapes, portraits, still life, snap shots, casual, and close-ups.

Engineered for those who see photography as a critical expression of self, our Art line offers sophisticated optical performance and abundant expressive power to deliver faithfully on your artistic vision.
The aspherical lens complex allows freedom of design, improved performance, a reduced number of component lenses and a compact size.
These are special lenses designed for APS-C size sensors so that the image circle matches the smaller size of the image sensor of most digital SLR cameras. Their specialized design gives these lenses the ideal properties for digital cameras, the compact and lightweight construction is an added bonus!
This lens uses a motor driven by ultrasonic waves to provide a quiet, high-speed AF.
To ensure stability in focusing, this lens moves the inner lens group(s) without changing the lens' physical length.
