Macro Lens
70mm f/2.8 EX DG
The advent of digital SLR's requires optimum lens performance and therefore the very latest optical technology has been incorporated in the production of this medium telephoto macro lens. The 70mm focal length gives an equivalent field of view as the popular 105mm macro lens when used on digital SLR cameras with an APS-C size image sensor. The design of this lens makes it suitable for taking pictures in all situations both with natural light conditions or flash.
Macro lenses require a high imaging performance for photographing objects with digital SLR cameras
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.
