Continuing the Mamiya tradition of optical excellence, the 645AF system features a selection of six interchangeable lenses (with more to follow) with cutting-edge design and construction and employing Eco-Glass, a lead and arsenic free compound that provides unmatched optical qualities.

Wide angle lenses feature ULD (ultra-low dispersion) glass to correct chromatic aberration and optimise contrast and resolution at all apertures. A floating-element design contributes to consistent image quality at all focusing ranges, from macro to infinity.

Telephoto lenses are designed to minimise flare and ghosting and achieve excellent image fidelity and contrast.
