SIGMA 4.5/2.8 EX DC CIRCULAR Fisheye HSM Nikon
This lens produces a ring image with an angle of view of 180 degrees in all directions when using the camera with APS-C sensor. Aperture F2.8 allows a clear view in the viewfinder and shooting in low-light conditions. Because it gives a measurable relationship between the angle and the image it is suitable for scientific and technical applications. Due to the enormous viewing angle it is very interesting lens for recording of 360 spherical video because you only need three APS-C cameras to cover the whole sphere.
