opteka platinum series 0.2x low-profile "ninja" fisheye lens for jvc gz-hd500, hd520, hd620, hm300, hm320, hm340 and hm550 camcorders

An essential tool for extreme sports and dramatic action shooters. The 0.2X Ninja Fisheye Adapter offers an extreme fisheye effect and a high degree of barrel distortion. It exaggerates depth by pulling nearby objects closer and causing distant objects to recede into the background. Advances in high-index / low-dispersion optical glasses, new barrel materials, and exotic anti-reflection coatings, along with the latest in computer-aided-design / computer-aided-manufacturing, are combined to produce lenses of unprecedented quality.
