Specifically designed for digital SLR cameras equipped with APS-C size image sensors, the Sigma 10mm f/2.8 EX DC HSM Fisheye Lens is a lens that captures a rectangular 180° view in all directions (when mounted on Pentax SLR camera). The diagonal field of view of this fisheye lens produces striking images with exaggerated perspective and distortion.
The minimum focusing distance of 5.3" (13.5 cm) and maximum magnification 1:3.3 allows subjects to be as close as 0.7" (1.8 cm) from the lens' front element. This close focusing capability allows close-up photography and also it is possible to make use of large depth of field that covers a wide range of subjects. Even the most familiar and mundane of subjects can be portrayed with startlingly fresh new expressions through exaggerated perspectives and unusual distortion effects. Well suited for academic and technical measurements such as solid angle measurements, cloud cover measurements & virtual reality.
DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is made to match the smaller dimensions used for the image sensor on digital cameras. As a result, these lenses are also more compact and lightweight, and are better matched to digital SLR cameras.
Note! Not suitable for 35mm film SLR cameras, or for "full-frame" digital cameras
