The 17-70mm f/2.8-4 DC Macro OS HSM lens has various angles of view from wide angle to telephoto. It is a versatile lens ideal for several types of photography. The lens has a minimum focusing distance of 22cm and maximum magnification of 1:2.7. It has a 4.7cm working distance between the front of the lens and the subject which is convenient for taking close-up pictures. The lens is equipped with Sigma’s own unique OS function. This system allows the photographer to use shutter speeds approximately 4 stops slower. As compensation for camera shake is visible in the view finder, the photographer can easily check for accurate focus and ensure there is no subject movement. The large aperture provides a bright image through the viewfinder and enables photographers to easily check focusing and composition. An ELD (Extraordinary Low Dispersion) glass element plus one hybrid aspherical lens and two glass mold lenses offer excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting even when the subject is backlit and provides high contrast images. An inner focusing system and HSM (Hyper Sonic Motor) ensure quiet and high-speed auto focus. This lens has a rounded 7 blade diaphragm which creates an attractive bokeh. The inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the supplied petal-type hood and circular polarising filters. This lens is equipped with a zoom lock to prevent the lens from creeping due to its own weight, and to offer protection whilst the lens is being carried. A magnification scale is displayed on the lens barrel, ensuring ease of use.
