*Full circle can only be captured with full frame 35mm format digital SLR and film SLR cameras.
Auto-focus systemThis 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.
F3.5 maximum apertureThis lens is perfectly suited for low light conditions indoors or at dusk.
Close-up PhotographyThis 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.
Excellent optical performanceSpecial Low Dispersion (SLD) glass offer effective compensation of color aberration.
Reduction of flare and ghostingSigma’s super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras and also creates an optimum color balance.
An ideal lens for scientific applicationsDue 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.
Gelatin Filter HolderA holder at the rear of the lens accepts gelatin filters.
