• Bundle Includes: Sigma 24-70mm F2.8 DG OS HSM IF ART Lens for Canon EOS Digital Cameras, USB Dock for Canon Lenses, 64GB SD Card, USB 2.0 Card Reader, Professional Dust Blower, Screen Protectors, Universal Wireless Shutter Release, Sling Backpack, and 3-Piece Fundamental Filter Kit
• Usability and Durability: The Sigma 24-70mm Art brings a new level of usability and durability featuring a rugged metal barrel and an emphasis on image quality. Building off the experience from the 12-24mm Art, the aspherical elements used in the 24-70mm f/2.8 OS Art undergo a highly precise level of polishing, producing elements thicker in the center than on the edges
• Quiet and Fast Autofocusing: HSM lenses employ a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations
• Optical Stabilizer: This function utilizes a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating cameras movement when shooting by hand held camera
• Outstanding Optical Performance: Three SLD (Special Low Dispersion) glass lens elements and four aspherical lens elements minimize optical aberrations. To ensure outstanding edge-to-edge image quality, the optical system minimizes coma, which causes points of light to streak, and transverse chromatic aberration, which cannot be corrected via aperture control. The optical system also minimizes distortion, which can be especially prominent in wide-angle shots
