The compact Sigma 18-125mm f/3.8-5.6 DC HSM Zoom Lens is a high zoom ratio lens with SLD (Special Low Dispersion) glass, a molded glass aspherical lens and two hybrid aspherical lenses provide correction for aberrations. The super multi-layer coating reduces flare and ghosting. This lens has a minimum focusing distance of 13.8" at all focal lengths, and has maximum magnification of 1:3.8, making it ideal for close-up photography. This lens incorporates a HSM (Hyper Sonic Motor), which ensures a quiet and high-speed autofocus. It is the ideal lens for several type of photography such as wide-angle, telephoto and close-up.
Note! Autofocus does not work properly with the Sony Alpha SLT-A65 and SLT-A77 DSLR digital cameras. A free update is available from Sigma to correct this phenomenon and future production of this lens will be fully compatible with these cameras.
Vignetting will occur if the lens is used with 35mm SLR cameras or digital cameras with image sensors larger than APS-C size.
