What are the types of anamorphic lens?

The types of anamorphic lens mainly include the following:
Prism type deformable lens
Composed of multiple prisms, it achieves image distortion control through refraction, with the advantage of a large aperture and low brightness loss.  ‌
Lens group deformable lens
Composed of multiple lenses, it has a complex structure but can accurately control distortion, making it suitable for high-precision projection scenes with excellent imaging quality.  ‌
meniscus
Divided into positive meniscus (convex lens) and negative meniscus (concave lens), the deformation effect is achieved through different curvature combinations.  ‌
Double laminated lens
Made by bonding two lenses of different materials, with adjustable optical properties.  ‌
