The Mamiya RZ 110mm F/2.8 is a high-performance standard lens and the fastest, smallest and lightest lens in the RZ system. Mamiya lenses are quality controlled at all stages. They are engineered for professional use. Mamiya manufactures its own glass and coats the lens elements using Mamiya's proprietary multi-coating process, increasing light transmission, dramatically reducing flare, and ensuring crisp, clean whites and vibrant natural colors.
