About the product.
Mamiya-Sekor 80mm f/2.8 lens for the Mamiya C-series twin-lens reflex cameras, including the C220 and C330. The lens is fully working, aperture and shutter functions operating properly. Optics are generally clean with no fungus or significant haze. There is some very light dust inside and a few fine hairline marks/cleaning marks visible on the glass under direct light, as shown in the photos. The lens has been carefully stored in a dehumidifier to help protect it from humidity and fungus. Overall, a good clean, fully usable example of the classic Mamiya-Sekor 80mm f/2.8 standard lens for the Mamiya C-series TLR system.
