When you need to get a wider angle of view & add the Fisheye Adapter. The Fisheye produces an extraordinary degree of barrel distortion with a magnification factor of approximately .45X. It comes in popular Bayonet Mount that attaches with a twist to the front of the lens.
While extreme telephoto shots tend to flatten the subject against the background & the Fisheye exaggerates depth & pulling nearby objects closer and causing distant objects to recede into the background. Due to the Fisheye Adapter's characteristic barrel distortion & extreme low and high-angle shots are made more dramatic. An attic crawl space induces heightened claustrophobia. A forest of tall skyscrapers bend menacingly over the audience.
Because the Century Fisheye takes in a much wider angle of view than the human eye & it may be used to visually plunge the audience into a scene & surrounding them with a noisy crowd or exiling them to a lonely beach.
Focusing on the Sony PMW-EX3/EX1/EX1R
Like all fisheye adapters & the Century Fisheye uses the macro feature of the camera to achieve focus. Be sure the macro mode is enabled and the focus gear is engaged to auto focus & rotate ring 180 degrees.
NOTE: The full manual focus mode will not allow the adapter to focus and therefore CANNOT be used in conjunction with wide adapters and Fisheyes
