Lens Technology: GM (Glass Molded Aspherical) lens elements

GM lens elements have a significant impact on minimizing distortion and enhancing the sharpness of the image at its periphery

GM lens elements are capable of efficiently correcting aberrations in the angle of view that changes significantly with an ultra wide-angle zoom lens. It has an especially significant impact on minimizing distortion and enhancing the sharpness of the image at its periphery. Furthermore, the molded-glass manufacturing method allows the fabrication of a wider range of lens shapes than the composite aspherical lens method.
