 Sigma lens circular fisheye 8mm F4 EX DG : This lens is used to produce circular images, creating vast distortion with an angle of view of 180° when attached to a full-frame digital SLR camera. This one is equipped with a new multi-layer coating technology that reduces both flare and ghosting and ensures accurate color and high image quality for both film and dSLR cameras. This lens can be used for the scientific applications such as the solid angle measurements of cloud distribution over the sky, the vegetation distribution of the forest, etc., due to the quantifiable angle/area relationship it produces. Also supplied with the lens is a fitted padded case and a gelatin filter holder at the rear, allowing the use of gelatin filters.
