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. This lens incorporates a wide glass moulded aspherical lens with Special Low Dispersion (SLD) glass to compensate for aberrations and curvature at the widest angle, has a 9 blade rounded diaphragm to create attractive round bokeh at large-aperture settings, and an inbuilt HSM (Hyper Sonic Motor) that ensures a silent, high-speed AF. Ideal for landscapes, portraits, still life, snap shots, casual, and close-ups, this lens is suitable for crop (APS-C) sensor cameras

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.
