Sigma 8mm f/3.5 EX DG Circular Fisheye (Sigma Fit)
This 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 fast maximum aperture of F3.5 and a minimum focusing distance of 13.5cm. Sigma's super multi-layer coating and Special Low Dispersion (SLD) glass provide excellent image quality for digital and film SLR cameras. The special fisheye design allows maximum creative expression.
This fisheye lens 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.
Excellent optical performance
Special Low Dispersion (SLD) glass offer effective compensation of colour aberration.
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 colour balance.
This lens is ideal for photographers using computer stitching software which requires circular fisheye images to be input, resulting in stitched panoramas.
