Key features
DG
Sigma’s DG lenses are designed for cameras with a full-frame sensor, but cameras with a cropped sensor can also take these lenses. These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for Digital SLR Cameras whilst retaining suitability for traditional 35mm SLRs.
EX
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
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 colour 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 polarising 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.
