Description:
Sunex SuperFisheye lens is a new type of fisheye lens developed exclusively for digital SLR cameras using APS-C or DX format imagers. Unlike other fisheye lenses, Sunex SuperFisheye forms a complete circular image within the camera imager area. It captures a field of view 185° in a single shot. This high quality, yet simple-to-use lens features an optimized fixed aperture and focus to achieve the best image quality for panoramic photography. This lens is designed using the state of art optical design software taking advantage of newly available high-index glasses to achieve sharp image (download diffraction MTF curve ) from center to edge. BBAR coatings are applied to all air-glass interfaces to keep the overall flare/ghosting at a minimum.  We recommend our Dewarper DSLR distortion correction/optimization software for this lens.
