November 15, 2007: Sigma Corporation has released details of two new fisheye lenses that are designed specifically for DSLR cameras with ‘APS-C’ sized sensors.
Six aperture blades ensure attractive bokeh and quantifiable angle/area relationship parameters allow this lens to be used for scientific applications such as solid angle measurements of cloud or vegetation distributions. Minimum aperture is f/22. Its diameter is 76.2 mm and length is 77.8 mm and overall weight is 470 grams. It will be supplied with Sigma, Nikon and Canon AF mounts.
The 10mm F2.8 EX DC Fisheye HSM Fisheye lens consists of 12 elements in 7 groups and can focus down to 13.5 cm, with a maximum magnification of 1:3.3. The Nikon version of this lens produces a diagonal angle of view of 180 degrees(154 degrees for Sigma, 167 degrees for Canon) and produces striking images with exaggerated perspective and distortion. The Integral hood blocks out extraneous light and the Super Multi-Layer Coating minimises flare and ghosting. Diameter is 75.8 mm and length is 83.1 mm.
Both lenses are equipped with Sigma’s Hyper Sonic Motors (HSM), which ensure fast and quiet autofocusing and allow full-time manual focus override by rotation of the focus ring. They are supplied with a gelatin filter holder at the rear, allowing the use of gelatin filters. Both lenses feature equi-solid angle projection, allowing them to be used for scientific and fine art work. Release dates and pricing have still to be determined.
