The Sirui 1.25x Anamorphic Adapter enables you to convert any spherical lens into an anamorphic or increase the squeeze ratio of an existing anamorphic lens. Use it to create a 1.25x anamorphic effect with a spherical lens or a 2x squeeze with a 1.6x anamorphic lens. This lightweight and compact adapter mounts on lenses via a rear 82mm thread and can be used with separately available 92mm step-up or 67, 72, and 77mm step-down rings.
