This large aperture 30mm F1.4 EX DC HSM lens is designed to match the APS-C size image sensors of digital SLR cameras.
Two SLD glass elements are especially effective in the compensation of magnification chromatic aberration. A molded glass aspherical lens at the rear lens group reduces colour aberration and provides high-quality image results.
