Sigma 70mm F2.8 EX DG Macro For Sony D – DSLR Camera Lens

The Sigma Macro 70mm f/2.8 EX DG Lens is a medium telephoto macro lens which is ideal for both digital and 35mm film SLR cameras. The 70mm focal length gives an equivalent field of view to 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, 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 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.

Sigma 70mm F2.8 EX DG Macro For Sony D – DSLR Camera Lens

The Sigma 24-70mm f/2.8 EX DG Macro DF lens has now been optimized to capture superior quality images even with digital cameras. DG is a designation Sigma uses on lenses featuring optical systems designed to meet the performance characteristics of digital SLR cameras.

Responding to the demands from professional photographers for a constant aperture zoom lens with a wider view, this lens covers focal lengths from 24mm ultra wide angle to 70mm medium telephoto with a bright viewfinder and easy AF/MF all the way through.

  • Three aspherical lens elements minimize spherical aberration, astigmatism and sagittal coma flare
  • Use of two SLD (Special Low Dispersion) elements results in excellent correction of chromatic aberration (the propensity of different colors of light to focus before and after the film plane)
  • DF (dual focus) mechanism is incorporated, making it easy to hold the lens during AF while providing a wide focus ring for easy manual focus
  • Non-rotating lens front allows the use of a flower shaped “Perfect Hood” and makes employing polarizing filters a snap

Design Prioritizing Optical Performance

The Sigma Art Lens features an extending, floating and a two-group focus mechanism to produce top-level performance which helps to reduce the aberration, in order to produce optimal results at any focus distance, it also include two FLD glass elements, two SLD glass elements and one element with a high rate of anomalous partial dispersion to effectively reduce axial chromatic aberration.

Designed to Minimise Flare and Ghosting

Sigma has incorporated a Super Multi-Layer Coating in the 70mm f/2.8 DG Macro lens, that helps reduce the flare and ghosting when photographing images, even when shooting in backlit conditions. Photographers will appreciate this as it contributes to high quality and razor-sharp images.

Focus-by-wire System for Comfortable and Precise Focusing

Sigma has packed advanced features in the 70mm f/2.8 lens such as the focus-by-wire system that removes the direct mechanical connection between the focus ring and the focus drive system. A brand new coreless DC motor that allows you to adjust the focus with optimal speed and low noise has also been incorporated which is required for macro photography.

Fast Autofocus with Full-Time Manual Focus

The lens can easily be switched to manual focus by simply rotating the focus ring, all thanks to its full-time manual focus function.

Weather-Sealed Construction

The Sigma Macro 70mm f/2.8 Art lens features rubber sealing that helps protect the mount from dust and water drops.

Rounded Diaphragm

The Sigma lens features a rounded 9-blade diaphragm that creates attractive bokeh in the out-of-focus areas of the image.

High-precision, Rugged Brass Bayonet Mount

An exceptional durable lens is all thanks to its brass mount which combines high precision with a rugged construction.
