Wide angle lens attachment for camera - has two aspheric lenses with additive effect

摘要

The wide angle attachment has two aspheric lenses (11.1, 11.2) in a special fitting, screwed to the objective of the camera. The lenses can be separated and only one fitted to the camera for an intermediate reduction in focal length, in order to increase the range of the lenses. The two lenses are mounted in a common fitting, with the front lens removable and leaving the rear lens on the objective. The additive effect of both lenses provides extra short focal length for special effects.
