The Vlogmagic 0.3X HD Ultra Fisheye Lens Adapter uses multi-coated, low-dispersion glass to produce crisp, high-definition video images. Great for dramatic effects and extremely wide fields of view--think sports, think dream sequences, think the HAL-9000 computer--this fisheye adapter screws onto the front of your existing camcorder lens and bends a 180° view into a peephole-style circle. Straight lines become curved, noses become bulbous, eyes become goggly, and objects in your viewfinder will be closer than they appear. HD2: High Definition 2, 2x the resolution of standard high definition lenses. DMC: Digital Multi-Coated, greatly reduces the appearance of lens flare and ghosting caused by reflections. BAB: Internal Black Almite Barrel, black matte satin finish reduces reflections. BRG: Black Rimmed Glass, reduces the chance of light reflecting off the edge. High-index / low-dispersion optical glass, fully multi-coated, every element, high speed auto-focus / infrared compatible, maximize day & night shots by providing maximum light transmission. NOTE: This fisheye lens only fits for camcorders. Please confirm your camcorder lens thread size before purchasing. We offer 52MM/58MM/62MM/67MM/72MM size.
