Sigma announces 17-70mm F2.8-4 DC MACRO OS HSM / DC MACRO HSM large-aperture APS-C standard zoom lens

Sigma today announced the release of the new Sigma 17-70mm F2.8-4 DC MACRO OS HSM / DC MACRO HSM, the large-aperture APS-C standard zoom lens with a focal range that covers all your everyday needs along with macro functionality. With its wide zoom range, the lens has a focal range equivalent to 25.5-105mm on a 35mm lens. Thanks to Sigma’s latest technologies, it’s exceptionally lightweight and 30% more compact by volume than previous lenses of its type. Its low F-number equips photographers to shoot subjects at extremely close range, making this the perfect lens for travel, family photos, artistic compositions, and many other uses.

Sigma’s own unique OS (Optical Stabilizer) function is incorporated. It offers effective correction of approximately 4 stops, which makes it possible to compensate for camera shake even in macro range photography where a small blur can be easily identified (not available with Sony or Pentax mounts). A complement to uncompromising optical performance, functionality, quality, and elegance, the compact size of the lens makes it ideal for everyday use. It is highly beneficial to photographers that the lens they use the most is one of the best in quality they have.

To offer top image quality throughout the zoom range, the lens features 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, as well as a SLD (Special Low Dispersion) glass, which helps minimize chromatic aberration. The result is superior image quality from infinity to macro distances. Double aspheric lenses produced by precision glass molding and a newly designed cam with a highly complex structure help minimize astigmatism and other forms of aberration and realize top image quality. The bright finder lets photographers compose their images easily.

Sigma 17-70mm F2.8-4 DC MACRO OS HSM / DC MACRO HSM APS-C standard zoom lens measures 79mm x 82mm and weigh 465g.
