An infinite number of lenses in just one lens: ML-20-35 is a shape-changing polymer lens. The spherical curvature of this lens with an aperture of 20 mm can be changed manually by rotating an adjustment ring. The focal length can be changed from positive (plano-convex) to infinity (flat) to negative (plano-concave).
