The Cyclopital3D 28mm Wide Angle Lens Adapter is compatible with JVC 3D Camcorders GS-TD1 & GY-HMZ1U ProHD. The Cyclopital3D Wide-angle lens allows you to vary your techniques by extending the field of view (FOV) to 64 degrees. This lens could be considered a "fish-eye" type lens. The 86mm lens ring allows you to add several accessory optics to the lens as well, from neutral density filters, polarizers, lens hood and more.
In addition to the obvious advantage of getting more in the scene, you can also get a little closer to your subject when "infinity" is in the background while maintain the same amount of parallax in the scene.
