Product description
Announced Nov 14, 2007

The 4.5mm F2.8 EX DC Circular Fisheye HSM is a true fisheye optic for crop cameras, projecting a circular 180-degree image onto APS-C sensors. This lens sports a focal length of 4.5mm and maximum aperture of F2.8, Sigma's HSM ultrasonic-type focusing and SLD low-dispersion lens elements. Aside from 'edgy' skateboarding shots, circular fisheyes are actually quite useful for astrophotography and scientific applications.
