Photos Taken with This Lens


  • This compact, versatile lens includes Sigma’s optical stabilization (OS) function and is ideal for all types of photography, offering an incredible 16.6x zoom range with coverage from a wide-angle of 18mm (equivalent to 27mm on a full-frame camera) to a telephoto of 300mm (equivalent to 450mm on a full-frame camera), as well as macro.
  • Aspherical Lens Elements - Aspherical lenses offer greater design latitude, raise performance, permit use of fewer lens elements and allow a more compact size. The 18-30mm incorporates 4 FLD (“F” Low Dispersion) glass elements in addition to 1 SLD (Special Low Dispersion) glass element. These new elements help to minimize chromatic aberration, especially toward the telephoto-end, and provide clear image quality with high colour fidelity.
  • Newly Developed OS System - Sigma engineers have worked closely on the image stabilization system, from construction to firmware algorithims, in an effort to achieve 3.5 stops of compensation. Assuring a sharp image while giving you freedom of movement and more latitude in camera settings.
  • Optical Stabilizer - An optical stabilizer mechanism helps assure a sharp image while giving you freedom of movement and more latitude in camera settings.
  • New close-up lens attachment offering magnification ratio of 1:2 - This lens features a minimum focusing distance of 39 cm and a maximum magnification ratio of 1:3, making it possible to shoot subjects as close as macro lenses. To get even closer, Sigma has developed the AML72-01 close-up lens (sold separately), offering a maximum magnification ratio 1:2 while maintaining outstanding quality.
  • This lens incorporates a brass made bayonet mount which has both high accuracy and durability.
  • Made in Japan
  • Sigma USB DOCK compatible lens - user friendly and easy precise customization. Update new lens firmware; adjust focus position and other parameters by connecting the lens to a USB DOCK. (USB DOCK sold separately MSRP $79.95).
  • Available mount conversion service (charges apply) - Sigma’s new mount conversion service will be available for this lens and other Sigma interchangeable lenses. Sigma will convert the current lens mount and internal components to work on a different camera brand, allowing you to continue using your favourite Sigma lens with a different camera body.
