Sigma 4.5mm EX F2.8 EX DC HSM Circular Fisheye Lens

Sigma today announced its (and probably the world’s) first true fisheye optic for crop sensors, projecting a circular 180° image onto APS-C sensors.

Sigma says the 4.5mm EX F2.8 EX DC HSM Circular Fisheye Lens has a fast maximum aperture of F2.8 making it ideal for low light photography. It has a minimum focusing distance of 13.5cm and a maximum magnification of 1:6 useful for macro shots.

The new fisheye lens 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 autofocusing and allows full-time manual focus override by rotation of the focus ring.
