For use with any Canon full frame DSLR cameras, the Sigma 24-70mm f2.8 EX DG HSM Zoom Lens is a professional standard lens that gives incredible clarity and image quality even in low light conditions. Compact construction At just 94.7mm long this is a very adaptable and easy-to-use lens that gives exceptional results when shooting landscape shots, portraits and everything between. The multi-layer lens coating greatly reduces flare and ghosting, allowing optimum colour balance throughout the entire zoom range and adding a new depth to your pictures. Large aperture Especially suited to low light conditions and indoor shooting, the large aperture opens up a whole new avenue to your photography. With nine rounded blades making up the diaphragm you can add creative touches to your photography, using it to soften and blur the out-of-focus areas of your image as well as a petal-type hood to help reduce unwanted light and internal reflections. With the flexibility to switch easily from auto focus to manual it's easy to capture what you want exactly how you want. Internal Focus Using Internal Focus technology to eliminate front-end rotation, this Sigma lens greatly reduces potential fluctuation of aberration to give you much more control and reliability when shooting, with the lens doing all the hard work to give you outstandingly sharp images. Hyper Sonic Autofocus The Hyper Sonic Motor works silently and quickly when set to auto focus so you don't miss your shot. The action is smooth and responsive and works quickly to let you capture crystal clear images every time. SLD Glass Optical Construction Three SLD (Special Low Dispersion) glass elements combine to give you incredibly high resolution and superb image sharpness to capture the best images possible with this user-friendly and highly useable lens. Versatile and functional, the Sigma 24-70mm f2.8 EX DG HSM Zoom Lens is a great all-round lens that produces exceptional results whatever the subject.
