Product Description
Large aperture F3.5 circular fisheye lens with close up capability, optimized
for use with digital SLR cameras.
This circular fisheye lens produces circular images with an angle of view of
180 when attached to a full-frame digital SLR or 35mm film SLR camera. It has
a fast maximum aperture of F3.5 and a minimum focusing distance of 13.5cm
(5.3). Sigmas 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.
Auto-Focus System
This circular fisheye lens produces circular images with an angle of view of
180and 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.
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.
Excellent optical performance
Special Low Dispersion (SLD) glass offer effective compensation of color
aberration.
Reduction of flare and ghosting
Sigmas 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 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.
Gelatin Filter Holder
A holder at the rear of the lens accepts gelatin filters.
