| Sigma Corporation is pleased to announce the launch of the new 8mm F3.5 EX DG CIRCULAR FISHEYE lens. This circular fisheye lens produces circular images with an angle of view of 180° when attached to a full-frame digital or 35mm film SLR camera. It has a maximum aperture of F3.5, a minimum focusing distance of 13.5cm (5.3″) and a maximum magnification of 1:4.6. The special fisheye design allows maximum creative expression. Sigma’s super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras. Special Low Dispersion (SLD) glass offer effective compensation of color aberration. Providing excellent image quality for digital and film SLR 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 rain forest canopy, etc., due to the quantifiable angle/area relationship it produces.
