It has a maximum aperture of f3.5, a minimum focusing distance of 5.5-inches and a maximum magnification of 4.6x. 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. The new lens power layout reduces color aberrations. 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. This lens has a gelatin filter holder at the rear, allowing the use of gelatin filters.
DG (DG lens)
These are large-aperture lenses with wide angles and short minimum focusing distances. With an abundance of peripheral illumination, they are ideal lenses for digital SLR cameras whilst retaining suitability for traditional 35mm SLRs.
EX (EX lens)
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
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.
F3.5 maximum aperture, this lens is perfectly suited for low light conditions indoors or at dusk.
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.
Special Low Dispersion (SLD) glass offer effective compensation of color aberration.
Sigma's super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras and also creates an optimum color balance.
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.
