The Optex 5.5 S16 lens is an ultra-wide-angle prime lens designed for the Super 16mm film format and modern digital cameras that cover the S16 sensor size. It’s a highly regarded staple in S16 cinematography, often used for its dynamic perspective without the extreme distortion typically associated with fisheye lenses. It’s known for being one of the widest rectilinear lenses available for the format.
