The Mamiya 210mm f/4.5 APO is the shortest focal length in the Mamiya RZ APO series, utilizing ultra-low dispersion glass and computer aided design to eliminate chromatic aberration common to telephoto lenses over 200mm focal length.

Mamiya lenses are quality controlled at all stages. They are engineered for professional use. Mamiya manufactures it's 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.
