18-35mm F1.8 DC HSM A - Canon EOS

  The Sigma 18-35mm f1.8 DC HSM Lens was 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 Lens Construction 17 elements in 12 groups Angle of View (for SD1) 76.5 - 44.2 degrees Number of Diaphragm Blades 9 Blades (Rounded diaphragm) Minimum Aperture F16 Minimum Focusing Distance 28cm / 11.0in.
