Sigma Announces Two NEW Lenses - 50mm prime & 18-200mm telephoto zoom


Sigma 50mm F1.4 DG HSM

First up is the Sigma 50mm F1.4 DG HSM lens, which is part of Sigma’s relatively new “Art” line of lenses.

For axial chromatic aberration this prime lens has incorporated “Special Low Dispersion” (SLD) which should ensure high image quality throughout the entire focusing range.

The Sigma 50mm F1.4 DG HSM has each glass element positioned to optimise the power layout at respective positions, and succeeds in minimising distortion.

The lens also incorporates a floating system that adjusts the distance between lens groups while focusing, thereby reducing the amount of lens movement required. This achieves a minimum focusing distance of 40cm and maximum magnification ratio of 1:5.6.




Other features
  • Super Multi Layer Coating, which reduces flare and ghosting while providing sharp and high contrast images even in backlit conditions.
  • A Hyper Sonic Motor (HSM) which delivers high AF speed and extremely quiet performance.
  • 9 blade-rounded diaphragm to create an attractive blur to the out of focus areas of the image.
  • A brass made bayonet mount.


Sigma 18-200mm F3.5-6.3 DC Macro (OS) HSM

From the “Contemporary” line of lenses comes the new Sigma 18-200mm F3.5-6.3 DC Macro OS HSM and Sigma 18-200mm F3.5-6.3 DC Macro HSM.

This lens has been redeveloped as the standard zoom lens from Sigma’s new product line, which has higher performance, is even smaller and lighter-weight, and on top of that, includes “the macro features”.

With this lens you can enjoy the variation of different angle-of-views, from a wide-angle of 18mm to a telephoto of 200mm, as well as macro. It is a perfect entry-level interchangeable lens.

This Sigma zoom lens incorporates “Special Low Dispersion” (SLD) glass elements that have a high refractive index, and corrects chromatic aberration at the telephoto-end very well. 

One of the biggest features of this super zoom is that it is possible to shoot subjects as close as macro lens. This lens features a minimum focusing distance of 39cm and a maximum magnification ratio of 1:3.


Other features
  • An Optical Stabiliser system, which offers superior stabilisation.
  • Super Multi Layer Coating, which reduces flare and ghosting while providing sharp and high contrast images even in backlit conditions.
  • 7 blade-rounded diaphragm.
  • A Hyper Sonic Motor (HSM) which delivers high AF speed and extremely quiet performance.
  • Brass made bayonet mount.
These lenses will be available to pre-order from Digital Camera Warehouse soon.
