HDP-5072EX High-Definition Semi-Fisheye Converter 0.5x The Raynox HDP-5072EX is a 0.5x semi-fisheye converter specifically designed for use on fast high-definition camera lenses, achieving a high resolving power of 630 line pairs per millimeter (at the center of the image at an MTF contrast of 30%). With the HDP-5072EX in front of a high-definition camera lens, the angle of view increases by 100% compared to that of the lens when set to the shortest wide-angle focal length. Especially when shooting from a short distance with this HDP-5072EX in front of the lens, interesting semi-fisheye effects result due to the barrel distortion of -31%, while at long distances this distortion is hardly noticeable anymore and panorama shots with a strongly extended angle of view are possible as with a 0.5x wide angle.
