KIPON LPL 1.65x Rear Anamorphic Adapter

The KIPON BAVEYES LPL > LPL 1.65x Rear Anamorphic Adapter is engineered to bring out the best in ARRI Signature Prime lenses by vertically stretching the image by 1.65x, achieving a captivating widescreen aesthetic. Designed with the essence of a front anamorphic lens, it delivers a sharp central focus with a gradual falloff in sharpness toward the edges, creating a balanced, natural cinematic effect.

Crafted with five cylindrical lenses, this innovative optical design allows a slight, intentional distortion to emulate the authentic anamorphic look filmmakers love, enhancing the immersive quality of each shot. The adapter is compatible with LPL mount lenses up to 16.5mm depth (from the LPL flange) and supports a maximum T-stop of T2.8, accommodating large sensor sizes up to 44.8mm diagonally, like those of the ALEXA LF.

With a light transmission reduction of just 1.25 stops, this adapter preserves excellent brightness and detail while providing an integrated electronic interface for ARRI’s Lens Data System (LDS). This allows smooth communication between the camera and lens, ensuring precise lens data for an enhanced workflow and a true anamorphic experience.

The optical design consisting of 5 lenses in 5 groups uses high refractive index and low dispersion glass and has been optimized for maximum contrast transmission and minimum aberrations with state-of-the-art optical design software. Tolerance and stray light analysis by special software, avoids ghosting and reflections already at the design stage and ensures maximum imaging performance.

Cinematic Anamorphic Effect

While rear anamorphic adapters do not produce oval bokeh or horizontal flares, the 1.65x factor allows for a gentle sharpness falloff toward the edges and a touch of controlled distortion, closely emulating the cinematic feel of front anamorphic lenses. This subtle effect enhances depth and creates an organic look, making it ideal for projects where the goal is a natural, immersive aesthetic.

Overall, using a 1.65x anamorphic factor on ALEXA LF cameras with ARRI Signature Primes provides an effective combination of resolution, aspect ratio, and cinematic character, enabling filmmakers to capture the anamorphic look without compromising the quality and detail that ARRI’s large-format sensor and premium lenses are known for.
