Photographic fisheye lenses with fixed focal length for cameras with different sensor formats have been well developed for decades. However, photographic fisheye lenses with variable focal length are rare on the market due in part to the greater design difficulty. This paper presents a large aperture zoom fisheye lens for DSLR cameras that produces both circular and diagonal fisheye imaging for 35-mm sensors and diagonal fish- eye imaging for APS-C sensors. The history and optical characteristics of fisheye lenses are briefly reviewed. Then, a 9.2- to 16.1-mm F ∕2.8 to F ∕3.5 zoom fisheye lens design is presented, including the design approach and aberration control.

  • Fisheye Lens Designs and Their Relative Performance
    Fisheye lens designs and their relative performance James “Jay” Kumlera, Martin Bauerb aCoastal Optical Systems, 4480 South Tiffany Drive, West Palm Beach, FL 33407 bInternet Pictures Corporation, 1009 Commerce Park Drive, Oak Ridge, TN 37830 ABSTRACT New panoramic and immersive digital imaging developments have generated increased interest in high performance fisheye camera lenses suitable for 35 mm single lens reflex (SLR) cameras. Special concerns for such applications are the uniformity of illumination and radial image mapping. Because two hemispherical images are digitally stitched together to form a complete 360-degree x 180-degree image, the performance of the lens at the 90 degree (preferably more than 90 degree) edge of the fisheye image is just as important as the center of the image. Lateral color, high order distortion (edge compression) and severe drop-off of illumination at the full field become obvious image defects and cause seams in the immersive image. Fisheye lens designs have widely varying relative illumination and distortion across the hemispherical field of view of the lens. After describing the contributing factors to relative illumination, we survey a collection of fisheye designs and compare their illumination performance, radial mapping and lateral color. A new method of measuring relative illumination and radial mapping in the laboratory is described and results on commercially available fish-eye lenses are presented. Keywords: Fisheye lenses, optical design, relative illumination, distortion testing. 1. DEFINITION OF FISHEYE LENSES 1.1 Origin of the term “Fish-eye” and all sky lenses Robert W. Wood originally coined the term “fish-eye” in his book Physical Optics1 in the context of a discussion about the refraction of light and the refraction of rays entering the level surface of a pond.
