Sigma 70mm f/2.8 Macro EX DG

Press Release:
The Sigma Corporation is pleased to announce the launch of the new MACRO 70mm f/2.8 EX DG lens. This medium telephoto macro lens is ideal for both digital SLR cameras and 35mm film SLR cameras.

The design of this lens makes it suitable for taking pictures in all situations from infinity to 1:1 macro, both with natural light conditions or flash. 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.

Sigma’s super multi-layer lens coating reduces flare and ghosting, and helps create a natural color balance. The floating focus system provides extremely high optical performance from infinity to 1:1 Macro. A ‘Focus Limiter Switch’ in incorporated on the lens, improving the speed and accuracy of autofocus by limiting the focus range. A screw-in lens hood is included for convenient use of circular polarizing filters.
