    Features

    Auto-focus system

    This circular fisheye lens produces circular images with an angle of view of 180°and also incorporates an auto focus system to achieve accurate focusing that might be difficult through the camera`s viewfinder due to the extremely large depth of field.

    Reduction of flare and ghosting

    Sigma’s super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras and also creates an optimum color balance.

    F3.5 maximum aperture

    This lens is perfectly suited for low light conditions indoors or at dusk.

    Close-up Photography

    This circular fisheye lens has a minimum focusing distance of 13.5cm (5.3″) and a maximum magnification of 1:4.6 making it particularly useful for close-up photography.

    An ideal lens for scientific applications

    Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific applications such as solid angle measurements of cloud distribution over the sky, or vegetation distribution of the rain forest canopy.

    Excellent optical performance

    Special Low Dispersion (SLD) glass offer effective compensation of color aberration.

    Gelatin Filter Holder
