This is the "ULANZI 1.33X Anamorphic Lens 17mm". It has only been used once after purchase, and there are no scratches on the lens. Two smartphone adapters are included. Anamorphic lenses are special lenses used to shoot and play back wide-screen movies on film. They stretch the image to a 2.39:1 aspect ratio Cinemascope size, and are characterized by an oval-shaped depth of field and a 1.33x magnification. When attached to a smartphone, you can shoot with a 2.4:1 Panavision aspect ratio. To edit, you will need a video editing app like "FiLMiC Pro" for iPhone/iPad/Apple Watch. #anamorphic #anamorphic #uranzi
