Written by: Tiffany Joyce
Sigma announces the release of two new Fisheye Lenses. The 4.5mm F2.8 EX DC CIRCULAR FISHEYE HSM and the 10mm F2.8 EX DC FISHEYE HSM lens are both for exclusively designed for digital SLRs with an APS-C size sensor. Both lenses use Sigma’s Hyper Sonic Motor (HSM) for fast and quiet focusing and allows full time manual focus override by rotating the focus ring.
The biggest difference between the two lenses is that the 4.5mm F2.8 EX DC CIRCULAR FISHEYE HSM has a full 180 degree angle of view in all directions making it ideal for Astrophotography and Aurora photography.
The two models will be available by December 2007.
