The HDP-5072EX is a 0.5x semi-fish eye conversion lens particularly designed for use with the high definition large aperture camera lens, and it has a resolution power of 630 lines/mm at center (MTF30%). With the HDP-5072EX lens mounted on a high definition camera's lens, it broadens 100% more the field of view than the original widest angle of view. In shooting a subject of short distance with HDP-5072EX lens on, it creates an interesting image of semi-fisheye effect, taking an advantage of the -31% distortion nature, but it takes a panoramic picture of 0.5x wide angle coverage without bothering the distortion image, when taken a distant subject.
