SigmaSigma 4.5mm F2.8 EX DC Circular Fisheye HSM lens : The Sigma Corporation is pleased to announce the launch of the new 4.5mm F2.8 EX DC Circular Fisheye HSM lens. This autofocus circular fisheye lens has an angle of view of 180 degrees in all directions. It is exclusively designed for digital SLR cameras with the APS-C size image sensor. When used in conjunction with digital SLRs with APS-C size image sensors, it produces circular image within the frame. The F2.8 large aperture value produces a bright image in the viewfinder and allows photographers to take pictures in low light conditions, making it an ideal lens for Astrophotography and Aurora photography. The HSM (Hyper Sonic Motor) ensures fast and quiet auto focusing.

Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific and arts applications such as solid angle measurements of cloud distribution over the sky or vegetation distribution of the forest. The minimum focusing distance of 5.3 inch and maximum magnification of 1:6 make it particularly useful for close-up photography. SLD (Special Low Dispersion) glass provides effective compensation of chromatic aberration. Sigma’s Super Multi-Layer Coating minimizes flare and ghosting. It is equipped with an inner focusing system that creates high definition and good image quality over the whole frame. The HSM (Hyper Sonic Motor) ensures fast and quiet auto focusing and allows full-time manual focus override by rotation of the focus ring.
