What is the function of anamorphic lenses?

The functions of anamorphic lenses mainly include the following aspects:
Compression and expansion function: anamorphic lenses can compress images during photography, usually with a compression ratio of 2 times, and expand and restore narrow distorted images during projection, thereby presenting a wider field of view and more surrounding environments in the picture.
Reshaping the image: The anamorphic lens compresses and reshapes the real-life image, solidifying the processed image onto a sensor or film. This technology aims to present a wider lens field of view and more surrounding environment than ordinary lenses by squeezing images.
Unique visual effects: Transfiguration lenses can create a unique visual experience, making the picture full of cinematic feel. Its unique imaging method gives the out of focus area a more "oily" texture and can produce obvious elliptical blurred light spots.
Application scenarios: Transfiguration lenses are widely used in film shooting, especially in scenes that require a wide field of view and immersion. They can help filmmakers create stronger visual impact and immersion.
Technical principle: The key to anamorphic lenses lies in the spherical lens filming technology, which is composed of curved glass elements that can cleverly "squeeze" and reshape real-life images. Through the clever use of various components such as prisms and cylinders, the imaging effect of the deformable lens is significantly improved.
