The Mamiya 300mm f/4.5 APO is a high-quality Apochromatic (APO) telephoto lens featuring Internal Focusing (IF).
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.
