SPECIFICATIONS:

• An easy to use 70mm medium telephoto macro lens
  This lens would have an equivalent field of view of a 105mm telephoto macro lens when used on digital SLR cameras with an APS-C size image sensor. The narrow angle of view is a great aid for simplifying backgrounds and shallow depth of field makes it easier to handle the composition.
• Compensate for colour aberration
  A Special Low Dispersion (SLD) lens and two high refractive index SLD lenses provide excellent correction for all types of aberrations and produce an exceptional level of optical performance.
• Reduce Ghosting and Flare
  Sigma’s super multi-layer lens coating reduces flare and ghosting, and helps create a natural color balance.
• Floating Focus System
  The floating focus system provides extremely high optical performance from infinity to 1:1 Macro.
• Focus Limiter Switch
  A ‘Focus Limiter Switch’ in incorporated on the lens, improving the speed and accuracy of autofocus by limiting the focus range from 25.7cm to 48cm and 55cm to infinity.
• A screw-in lens hood
  A screw-in lens hood is included for convenient use of circular polarizing filters. The included hood (LH620-01) is designed so a 77mm lens front cap can be attached whilst the hood is in place.
• Magnification scale
  A magnification scale is displayed on the lens barrel, ensuring ease of use.
